2. Description of the Related Art In the automatic processing of various electric devices, electronic devices, mechanical devices or parts, a plate-like member such as a printed circuit board or a plurality of parts is vertically housed in a cartridge, and one in a predetermined direction. A supply device continuously supplies, conveys, and stores. FIG. 6 shows an example of a supply device in an automatic process. The feeding device shown in the figure is composed of a frame 1 which is a frame of the device, and a frame 1
A lift unit 2 which is arranged so as to be able to move up and down on one side of the inside, and which lifts a cartridge described later up and down, a drive unit 3 which moves the lift unit 2 up and down by a constant pitch, and four sensors 4a for detecting the position of the lift unit 4b, 4c, and 4d, and a lifter position detection unit 4 and a pusher unit 5 that is arranged on the other side of the frame 1 so as to be able to move forward and backward and that sends the plate-shaped member loaded in the cartridge to the next process. Composed.
7 and 8 are explanatory views of the supply operation in the supply device, in which the lift section 2 on which the cartridge 6 is mounted is
The drive unit 3 lowers the lift position sensor 4b until it is detected, and the detection stops the supply position, that is, the position of the next process rail 7 (operation 1).

After that, the plate-like member A loaded in the lowermost stage of the cartridge 6 is sent to the next step by the pusher portion 5 which is a linear moving body (operation 2). After supplying the plate-shaped member to the next step, the driving unit 3 feeds the cartridge at a constant pitch (interval between the plate-shaped members in the cartridge) to move it to the rail position of the next step (operation 3), and the pusher unit 5 moves the plate-shaped member. Supply to the next process (operation 4). After that, by repeating the same operation (operations 3 and 4), the plate members B, C, D, ...
It is detected that the end portion has been reached by, and the supply of all the plate-like members in the cartridge is completed (operation 5). After that, the lift portion 2 is lowered until it is detected by the lift portion position sensor 4d, and the lift portion 2 is stopped at the bottom dead center detected by the lift portion position sensor 4d (operation 6). It is detected that the supply operation of the strip-shaped member has been completed, and the lift portion 2 is again raised to the initial position by this detection operation.

[0004]

However, the cartridge 6 is distorted by being affected by the load, heat, humidity, etc. at the time of carrying work, and as shown in FIGS. 9 (a) and 9 (b), the next step is performed. When the delivery position is aligned with the upper position of the cartridge, when the position of the lift portion 2 is lowered and the plate member below the cartridge 6 is supplied, the supply position of the plate member is displaced. If the plate-shaped member is pushed out by the pusher unit 5 while the position of supplying the plate-shaped member is deviated, the plate-shaped member is damaged or the operation rate is reduced due to the stop of the supply operation. In the prior art, in order to correct the distortion of the cartridge 6, the lift portion 2
As shown in FIGS. 10 (a) and 10 (b), an inverted L-shaped correction jig 8 surrounding one side and the upper surface of the cartridge 6 is provided.
The clamp portion 9 provided at the tip of the upper part of the cartridge 6 is pressed against the top plate surface of the cartridge 6 to be pressed against the side surface of the jig 8 for correction.

However, in this conventional technique, since the correction jig 8 is provided, as shown in FIG. 3C, the cartridge 6 cannot be replaced during the supply, and the lift portion 2 is top dead. If it is not raised to the point, it cannot be replaced, and at this time, the number of man-hours required to raise the lift portion 2 is generated, and the workability is very poor. Further, when the jig 8 is retrofitted to an old type plate-shaped feeding device to which the correction jig 8 is not added, disassembling work of the lift portion 2 from the feeding device itself is unavoidable and very difficult. As described above, since the cartridge cannot be taken out during the supply, extra manual work and time are wasted. The present invention has been made in view of the above points, corrects the warp of the cartridge in the automatic process, and further reduces the waste of time due to the replacement work in the above-mentioned conventional technology, and enables the replacement work of the cartridge even during the supply. SUMMARY OF THE INVENTION It is an object of the present invention to provide a plate-shaped member supply device that is easily attached to a device to which an old type correction device is not added. Also,
It is another object of the present invention to be applicable to component positioning in general.

[0006]

In order to achieve the above object, the invention according to claim 1 of the present invention is such that a plate-like member is vertically mounted in a cartridge and the cartridge can be raised and lowered in a frame. In the automatic feeding device which is installed on the upper surface of the lift portion arranged in the above, and which feeds one by one from the uppermost portion or the lowermost portion of the cartridge in a predetermined direction according to the lifting operation of the lift portion, A warpage straightening device having linear moving bodies having different pressure differences from each other is arranged on both side surfaces orthogonal to each other, the linear moving body is projected, and both side surfaces of the cartridge are pressed against each other, whereby a plate-shaped member reference surface in the cartridge, and By positioning the transport reference surface in the next process, it is easier to take out the cartridge during the supply compared to the conventional method, and the old type parts It is also useful for retrofit to the charging device. In the invention according to claim 2 of the present invention, the above-mentioned correction device is used for various electric devices, electronic devices, mechanical devices,
Alternatively, in an automatic process of parts, in a positioning process in a direction orthogonal to the part conveying surface, linear moving bodies having different pressure differences in two directions can be projected to correct the part conveying position.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. It should be noted that, except for the main part of the present invention, it is almost the same as the conventional one, and therefore, the same parts as those of the conventional one are denoted by the same reference numerals, and only the newly added portion or the portion to which new explanation is added will be described using different reference numerals. To do. FIG.
Shows a component supply device equipped with the correction device according to the present invention, and a cartridge set in the component supply device. In the figure, the cartridge 6 is the one generally used in this kind of automatic supply, as in the conventional case.
A bidirectional removable shelf 6d is provided in the interior surrounded by a, the bottom plate 6b, and both side plates 6c, and plate-shaped parts are loaded in multiple stages inside the partition partitioned by the shelf 6d. The outline of the component supply device is almost the same as the conventional one, and the lift portion 2 is arranged so as to be able to move up and down inside the rectangular box-shaped frame 1.
This lift portion is connected to a drive portion 3 fixedly arranged on one side of the frame 1 so as to be able to move up and down through a guide 3a.

A sensor 4 is provided on one side of the inside of the frame 1.
Sensor unit 4 in which a, 4b, 4c, and 4d are vertically arranged.
Is provided. Although not shown, a pusher portion is arranged adjacent to the frame 1 so that the pusher portion can move forward and backward toward the inside of the shelf 6d.

In addition to the above-mentioned structure, in the present invention, a pair of right and left orthodontic devices 10 are arranged on the upper part of the frame 1 so that their tips are opposed to both side plates 6c of the cartridge 6. The correction device 10 includes a case 12 having a rectangular shape, a plunger 14 projecting at the tip of the case 12 so as to be retractable, and a guide roller 16 rotatably attached to the tip of the plunger 14. Inside the case 12, a hydraulic mechanism driven by the detection output of the sensor unit 4 or a reciprocating mechanism for converting rotation of a motor into reciprocating linear movement is incorporated to move the plunger 14 forward and backward. Both correction devices 1
Of 0, one is for reference positioning with respect to the cartridge 6, and the other is to receive a reaction force against the pressure for this reference positioning.
The pressure contact pressure of the cartridge 6 (on the left side for reference positioning in the figure) is set to a high pressure for reaction force reception.

Next, the operation of the component supplying apparatus having the above structure will be described with reference to FIGS. First, the operation 1 in FIG. 2 shows the initial state of supply start of the apparatus, and the sensor 4a detects the initial position. When the cartridge 6 loaded with the plate-shaped members A to L is installed on the lift unit 2 and the apparatus is driven, the lift unit 2 descends, and the sensor 4b detects the lowered position to stop the lift unit 2 ( Operation 2).
This stop position is a position where the lowermost plate member A is positioned on the surface facing the next process rail 7. In response to the stop position signal, the plungers 14 of the respective correction devices 10 project toward each other, and the tip guide rollers 16 thereof come into contact with the side surface plate 6c to clamp the cartridge 6 (operation 3). Due to this clamping pressure, the cartridge 6 which has been deformed has its cross section corrected into a square shape, and each plate member accurately faces the next process rail 7.
Next, the pusher portion (not shown) moves forward, supplies the plate-shaped member A onto the next process rail, and then moves back again (operation 4). Next, by driving the drive unit 3, the lift unit 2 descends at a constant pitch and stops at the next supply position of the plate-shaped member B as shown in FIG. 3 (operation 5). Even during this lowering operation, the plunger 14 keeps the projecting state and clamps the cartridge 6, but since it descends by its own weight as the lift section 2 descends while rolling the guide roller 16, there is no hindrance to the operation. Moreover, the reference positioning state is always maintained.

The second plate-shaped member B is also supplied to the next step by continuously projecting the pusher portion in the supply direction.
After that, by repeating the above operations 4 and 5, the plate-like members in the cartridge 6 are sequentially supplied to the next process. The lower sensor 4c is the uppermost plate member L.
When the last plate-shaped member L is supplied to the supply position (operation 7), the plunger 14 is retracted (operation 8) in response to the end of the operation (operation 8), and the cartridge 6 is unloaded. Put in the clamped state. After that, as shown in FIG. 4, the lift unit 2 further descends, and when this position is detected by the sensor 4 at the lowest position (operation 9), the drive unit 3
The lift unit 2 is raised, and the operation 1 is returned to the initial operation state. After that, the same work can be repeated by setting the cartridge again by an operator or automatic exchange.

Incidentally, the correction using the pressure difference at the time of the pressure contact of the present invention also serves as the positioning, and can be applied to the positioning in the steps such as processing and inspection of products. FIG.
In a product processing inspection step, a pad 26 is provided at the tip of a pair of plungers 24 projecting so as to be retractable from the partition wall 22 orthogonal to the transport direction of the article W moving on the transport path 20 according to the same principle as described above. By setting one of the plunger sides as a reference position with one partition as the reference surface 28, articles randomly conveyed on the conveyance path 20 can be aligned and conveyed at this position.

[0013]

As described above, according to the present invention, the linear moving member can be clamped and unclamped from the frame side around the lift portion by the retracting / retracting operation of the linear moving member, so that the cartridge can be easily taken out during the supply. In addition, even when retrofitting to an old type component supply device, there is an advantage that the retrofitting can be easily performed without disassembling the inside. Further, the present invention can be applied to positioning or positioning of a component conveying surface in an automatic process of an electric device, an electronic device, a mechanical device, or other parts.
