Description

[Detailed description of the invention] (a) Industrial application field The present invention is applied to a supply or storage device for plate-shaped members, when wiring boards, etc. are supplied from a stocker or stored in a stocker. Ru.

(B) Prior Art As a device for feeding plate-shaped members one by one, the one described in Japanese Utility Model Publication No. 47-8033 is common. In other words, the plate-like members are stacked flat in a tube and cut out one by one from the bottom end, but with this structure, a large load is applied to the lower stacked members, and it is difficult to cut out plates with high friction or scratches on the surface. In particular, there were problems when using it for wiring boards with printed wiring. Therefore, when supplying wiring boards, etc., it is often done by laying a row of flat boards on their sides, supporting them on a slope, and cutting them out from the bottom, with the weight of each board being shared by the slope. . An example of this can be found in Japanese Patent Application Laid-Open No. 55-56685. Such a slope is also used when the plate-like members are pushed up one by one from below and stored in a line. 7 and 8 show how the plate member 2 is supported by the slope 1. As shown in FIG. By the way, when the plate-shaped members 2 are supported on the slope 1 in this way, when the row of plate-shaped members 2 is lowered or raised along the slope 1, the plate-shaped members 2 at the top end of the row are moved to the position shown in FIG. As shown in Figure 8, the problem arises that it falls over.
Therefore, as shown in FIG. 9, it is often done to place a weight 3 on top of the slope 1 and push the row of plate-like members 2 from behind. A similar weight is also described in JP-A-55-56685. This weight 3 needs to be removed once when supplying a row of plate-like members 2 onto the slope 1 or when taking out a row of plate-like members 2, but conventionally, this removal work was done manually. This has become an obstacle to automation.

(c) Purpose of the invention The present invention has a structure in which a row of plate-like members stacked horizontally is supported on a slope, and the upper end of the row of plate-like members is pushed by a weight. The purpose is to enable separation of a weight from a column without manual intervention.

(d) Structure of the invention In this invention, the weight is moved along a track, and a belt is placed beside the track. The weight is pulled up by capturing the belt with a clamp device provided on the weight and driving the belt in a fixed direction. When the belt is released, the weight will fall freely.

(E) Embodiment FIGS. 1 to 4 show a plate-shaped member supplying device 10 which is an embodiment of the present invention. Reference numeral 11 denotes an inclined base, on which a flat plate member 12 is mounted.
rows are supported on their sides. At the bottom of the base 11, opposing guide walls 13 and 14 are provided for the guideway 1.
5, into which the rows of plate-like members 12 fit. Reference numeral 16 denotes a guide wall provided at a right angle to the lower end of the guideway 15 at a slight distance from the lower end of the guideway 15. The rows of plate-like members 12 stop there, and are pushed out laterally one by one by rods 17. It is something.

A pair of supports 18 are provided on the side edges of the belt 11.
18 are arranged at a distance from each other in the inclination direction, and these pillars 1
A pair of upper and lower guide bars 19, 19 between 8 and 18
across. The guide bars 19, 19 constitute a track 20 for the weight. Weight 21 is guide bar 1
It consists of a mounting part 22 through which 9 and 19 pass, and a pressing part 23 extending downward from the mounting part 22, and the track 2
0 slides smoothly. 24 is orbit 20
It is an endless belt placed beside and parallel to this, and at the bottom of the slope there is an idle pulley 2
5, the upper part of the slope is wound around the output shaft pulley 27 of the electric motor 26.
The electric motor 26 has a built-in speed reducer, which creates a large resistance to the force that attempts to rotate the output shaft even when the motor is not driven. Mounting part 2 of weight 21
Air cylinder 2 is attached to the side wall of 2 by a stay 28.
Fix 9. The belt 24 passes between the rod 30 of the air cylinder 29 and the side wall of the mounting portion 22. This air cylinder 29 constitutes a clamping means for the belt 24. Note that a guide wall 31 for aligning the guide walls 14 is provided between the supports 18, 18.

Next, the effect will be explained. In FIG. 1, the air cylinder 29 is inactive and does not exert any action on the belt 24, and the weight 21 pushes the row of plate-like members 12 with gravity, causing the end of the row to fall down. is prevented. In this state, the rod 17 separates and supplies the plate member 12. Plate member 1
2, the air cylinder 29 is operated to pinch the belt 24 between the rod 30 and the weight 21 as shown in FIG. 2, and the electric motor 26 is driven to pull up the weight 21. If the weight 21 is held in this position and the push plate 32 feeds in a supplementary amount of the plate-like member 12, then the belt 24 is released from the clamp, the weight 21 will freely fall and move the plate-like member 12 again.
Push the tail into the column.

Other embodiments are shown in FIGS. 5 and 6. This is a plate-like member storage device 40 by partially modifying the above-described plate-like member supply device 10. Regarding the components basically common to the supply device 10, the previous reference numerals will be used and the explanation will be omitted, and only the modified parts will be described. 41, 41 is taxiway 1
It is a claw body with a toe protruding from the lower end of 5. A pair of guide bars 42 protrudes from the outer surfaces of the guide walls 13 and 14, and the claws 41 are attached to the guide bars 4.
2 is slidably supported. Also, the guide bar 42
A support plate 43 is fixed between the tips of each pair, and an air cylinder 44 for moving the claw body 41 is attached to this support plate 43. 45 is a push-up rod that comes out and retracts from the guide wall 16;
It is provided in a position opposite to. 46 is guide wall 1
This is a stopper that protrudes from the guide wall 16 so as to face 3. Further, a push plate 47 is arranged between the pillars 18, 18 instead of the guide wall 31.

Next, the effect will be explained. The claws 41, 41 support the lower ends of the rows of plate-shaped members 12 with their claws protruding inside the guide path 15, as shown in FIG. In this state, one plate member 12 is sent under the guideway 15. Next, by the operation of the air cylinders 44, 44, the claws 41, 41 move outward to open the path to the guideway 15, as shown in FIG. 5, and at the same time, the push-up rod 45 hits the stopper 46 and stops. Push up the plate-like member 12. After the pushed-up plate member 12 completely enters the guide path 15, the claws 41, 41 move inward again, and the push-up rod 45 retreats. Then, a new plate member 12 is sent under the guideway 15, and the above-described operation is repeated. During this time, the weight 21 continues to press the upper ends of the rows of plate-like members 12. When the row of plate members 12 reaches a certain height, the rod 30 of the air cylinder 29 clamps the belt 24, and at the same time the electric motor 26 rotates to pull up the weight 21. At this point, as shown in FIG. 6, the pushing plate 47 advances and sends out a certain portion of the row of plate-shaped members 12 in the horizontal direction. After the pushing plate 47 returns to its original position after being sent out, the air cylinder 29 releases the clamp on the belt 24, and the weight 21 freely descends to press the new upper end of the row of plate members 12. be. It may be configured such that the belt 24 is reversed to lower the weight 21 and then the clamp by the air cylinder 29 is released.

(f) Effects of the invention In this invention, a belt for lifting the weight is arranged beside the track of the weight that presses the upper end of the row of plate-shaped members, and this belt is captured by the clamping means provided on the weight. By releasing the weight, lifting, lowering, and free-falling of the weight can be selected as appropriate, and by incorporating this into the control object, it has become possible to automatically operate the entire feeding device or storage device.
