DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magazine holder for storing a magazine in which parts are arranged and stored.

BACKGROUND OF THE INVENTION Conventionally, this type of magazine holder has had the structure shown in FIG. 12. That is, a plurality of magazines 101 can be stacked and stored with a slight gap in the width and length of the magazine 101 in which parts 100 are arranged and stored, and one end of the magazine 101 in the stacking direction is open. Component 1 is inserted from one end in the axial direction of the lowermost magazine 101, which has a box shape and is held at one end that is not open.
A holder 104 having a window A102 through which 00 can be ejected, a window B103 through which the magazine 101 can be ejected from one end in the width direction, and a window B of the holder 104.

-103, it has an elastic body 105 that restricts ejection of the magazine when no external force is applied.

The magazine holder configured as described above has a groove in which a plurality of parts 106 can be received flowing out from the window AlO2 formed in the magazine holder, and a plurality of them are fixed in parallel to a supply part 107. Detachable and attached.

Problems to be Solved by the Invention However, under such a configuration, the parts 100 that have flowed onto the chute 106 are used, and when the parts 100 in the magazine 101 at the lowest stage of the magazine holder are exhausted, the parts 100 in the magazine 101 at the lowest stage of the magazine holder are used up. 101 is ejected from the window B103 formed in the holder 104 by external force, but especially the magazine 1
010 When the width dimension is large and the cross-sectional shape is shown in FIG. 13, it is necessary to set the bottom 108 of the holder 104 to the width dimension of the magazine 101 or more, so the distance between the adjacent magazine holders is set to be at least the width dimension of the magazine 101. However, when a plurality of magazine holders are arranged in parallel, the occupied area becomes large.

Furthermore, when the magazine 1o1 is stored in the holder 104 and attached to the supply section 106, there is a risk that the parts 100 may flow out through the window AlO2 formed in the holder 104 during transportation.
When installing the parts 100, it is necessary to prevent the parts 100 from flowing out, which leads to a problem in that the workability becomes very poor.

In view of the above-mentioned drawbacks, the present invention provides a magazine holder that occupies the minimum required area even when a plurality of magazines are set in parallel, and that can be transported and attached without causing parts inside the stored magazine to flow out. It is something.

Means for Solving the Problems In order to solve the above-mentioned problems, the magazine holder of the present invention is capable of storing a plurality of magazines in which parts are arranged in a stacked manner, and is capable of storing a plurality of magazines in which parts are arranged in a stacked manner, and only both ends in the stacking direction are open. The holder is located at the bottom of the holder and can be rotated about one point. When the fulcrum is located inside the holder, rotation is restricted and the magazine can be placed. When the fulcrum is located outside the holder, it cannot rotate. This configuration includes a rotary shutter that secures a magazine movement path, and a receiving lever that is attached to the holder, has a fulcrum for the rotary shutter, and moves the fulcrum in and out of the holder.

Operation The present invention has the above-described configuration, so that even when a plurality of parts are installed in parallel, the area occupied is kept to the minimum necessary, and the parts stored in the magazine can be transported and installed without spilling out.

A plurality of magazines 1 are stacked and stored in a magazine holder 3 having a regulation guide 6.

A plurality of magazine holders 3 prepared by the above method are aligned with the holder guide 15 of the supply stock section 14 and pushed in until the position is regulated by the stopper 16. Next, in order to transfer the magazine 1 to the multiple rows of chutes 23 and multiple rows of guides 35 set in the supply section 19, the supply section 19 is placed at a position opposite to the hemlock 9 f1 position of the supply stock section 14.
moves. Next, the escape unit 43 moves and sequentially moves the lowest magazine 1 in the magazine holder 3 to the supply section 1.
It is transferred so that it can be held by the chute 23 and guide 36 of No. 9.

The transfer operation will be explained next. After the escape unit 43 has been moved to the 9th and 1st position of the hemlock to be transferred, the cylinder 47 fixed to the escape pace 44 protrudes from the compressed air pressure, and the pair of chuck claws 25 attached to the chute 23 of the supply section 19 are cammed. When the mechanism opens and releases the forced holding of the magazine 1 in the width direction, the cylinder 48 fixed to the escape space 44 is protruded by compressed air, and the holding slider 31 holding the bottom surface of the front end of the magazine 1 is moved in the direction of arrow f. to release the hold on the front end of magazine 1. Magazine 1 then falls from the front end,
Then, the rear end also falls and is stored in the packet 49 fixed to the escape space 44. Also, while the magazine 1 is falling, the rear part of the magazine 1 blocks light from the transparent photoelectric switch 6o fixed to the packet 49.
It is confirmed that the magazine 1 is securely stored in the packet 49. After confirming that the magazine 1 has fallen, the compressed air in the cylinder 48 is released and the holding slider 31 moves in the direction of arrow e. .

Next, the plate 52 is raised by the cylinder 53, and the rotary lever 67, which is attached to the plate 62 so as to be able to slide up and down and rotate, reaches its upper limit by the cylinder 68, and is rotated by the rotary cylinder 69. As a result, the rotary lever 67 is placed in a state where it is slightly spaced from the bottom surface of the magazine 1 at the lowest stage of the magazine holder 3 and overlaps the magazine 1. At this time, the magazine 1 to be transferred is activated by the reflective charging switch 61 fixed to the plate 62.
It is detected whether or not the magazine exists in the magazine holder 3, and if it does not exist, an alarm is generated.

Then, when the cylinder 56 is protruded by the compressed air, the pair of opening/closing levers 54 are swung, and the front and rear receiving levers 9 attached to the magazine holder 3 are swung in the direction of arrow C, and the front and rear presser levers 1o are moved. By swinging in the direction of the arrow, the magazine 1 above the lowest level in the magaran holder 3 is held, and by releasing the hold on the lowest magazine 1, the lowest magazine 1 falls only slightly. It is held by the rotary lever 67 of the escape unit 43.

Then, the rotary lever 67 is gradually lowered by the cylinder 58 until it reaches the lower limit. As a result, the front end of the magazine 1 is held at the bottom by the holding slider 31 attached to the chute 23, and the rear end is regulated in the width direction by the groove 36 formed in the guide 35 of the supply section 19. The bottom surface is held by a holding plate 37. As a result, the magazine 1 is moved to the rotary lever 57 of the escape unit 43.
The holding by the rotating lever 57 is released and there is a gap between the rotating lever 57 and the rotating lever 57.

Next, a pair of opening/closing levers 6 swing the receiving lever 9 and presser lever 10 attached to the magazine holder 3.
The compressed air in the cylinder 56 that drives the magazine 4 is released, and the receiving lever 9 swings in the direction of the arrow to move the magazine 1 at the lowest stage.
At the same time, the presser lever 1o swings in the direction of arrow C, and the magazine 1, which was held one step above the bottom step, falls and is held at the bottom step. At this time, the reflective charging switch 61 fixed to the plate 62 detects whether or not the magazine 1 has fallen to the lowest stage, and if it is determined that there is no magazine 1 at the lowest stage, an alarm is generated and the magazine 1 is Appeal for the need for supplies. Simultaneously with this detection, the battery should be transferred by means of two reflective charging switches 62, one on the front and the other, which are fixed to the plate 52 and whose optical axes are located below with a slight distance from the bottom surface of the magazine 1 at the bottom of the magazine holder 3. It is confirmed whether the magazine 1 has definitely separated from the magazine holder 3, and if the presence of the magazine 1 is detected in either the front or the rear, the operation of the entire apparatus is stopped as a transfer failure.

Next, the rotation of the rotation lever 57 is returned by the rotation cylinder 69, and the overlap with the magazine 1 is eliminated. Next, the plate 52 is lowered by the cylinder 53, and the compressed air in the cylinder 47 is released.
When the magazine 1 is retracted, the pair of chuck claws 26 close and forcibly hold the front end of the magazine 1 in the width direction. When the magazine 1 is transferred to the supply section 19, the magazine 1 is transferred to the chute 23.
The component 1 flows into and fills the groove 24 formed in the groove 24 . By sequentially repeating the above transfer operation, the plurality of rows of chutes 23 are filled with parts 2.

The parts 2 on the chute 23 are sequentially used by the insertion head 63 by being selectively moved by the supply section 19 to the position of the insertion head 63 having a pair of clamping claws 65 . When the number of parts 2 in the magazine 1 of the supply section 19 decreases due to use in the insertion head 63, and the rear end of the series of parts 2 passes the sensor 34 on the chute 23 for detecting the presence or absence of parts 2, the sensor 34 detects the presence or absence of parts 2. Detect out-of-stock items. Then, the escape unit 43 moves to the position corresponding to the magazine 1 in the supply section 19 where the component shortage has occurred, and transfers the magazine 1 in the magaran holder 3 to the supply section 19 by the above-described transfer operation.

The magazine 1 is replenished to the magazine holder 3 using the handle 8 of the magazine holder 3 from outside the drawing and feeding device.

Pull out the magazine holder 3 from the supply stock section 14,
Alternatively, when pushing in, a transparent photoelectric switch 18 fixed to the supply stock part 14 to prevent the transfer operation by the escape unit 43 is blocked by pressing the handle near the magazine holder 3 handle 8, and the magazine 1 is supplied. Therefore, all operations of the escape unit 43 are stopped.

By repeating the above cycle, parts can be supplied without stopping the device.

Also, when changing the parts 2 to be supplied, for the magazine holder 3iC, pull out the magazine holder 3 from the supply stock section 14, and then use the regulation guide A5 and regulation guide B6.
Change to match the dimensions of magazine 1. Regarding the supply section 19, the holding plate 37 of the guide 35 fixed to the supply frame 2o is moved in the direction d by the hook 39, and the rear end of the magazine 1 is released from being held on the bottom surface of the rear end of the magazine 1, and the rear end of the magazine 1 is moved downward. Pull it down, prevent the parts 3 from falling from the front end with your hands, and pull out the magazine 1 from the rear. Thereafter, the chute 23 and guide 36 fixed to the supply frame 2o are replaced with ones that match the magazine size.
