Description

[Detailed Description of the Invention] a. Purpose of the Invention (Field of Industrial Application) A dispensing device for plate-shaped articles according to this invention is used when assembling printed circuit boards used in various electronic devices.

(Conventional technology and its problems) When manufacturing printed circuit boards to be incorporated into computers and other electronic devices, an automatic mounting device pulls out the circuit boards with no components mounted on them from a shelf-like case called a magazine rack. After the parts such as IC chips are mounted on the board by this mounting device, the board with the parts mounted is returned to its original position in the case.

Each time the board storage case receives a board with components attached, it is raised and lowered by one pitch of the stored boards, leaving a space between them in the vertical direction, and then the next board can be loaded and unloaded. make it look like this.

Various structures have been considered for teller devices used for this purpose, but all of them have complex structures that cause high equipment costs.
Otherwise, the operation was uncertain and lacked reliability.

The depositing and dispensing device for plate-shaped articles of the present invention solves the above-mentioned inconveniences.

b. Composition of the invention (means for solving the problem) In the plate-shaped article retrieval device of the invention, there is a guide rail arranged horizontally, and a distal end that moves horizontally along the guide rail. A movable plate with a folded piece formed on the upper edge of the part is provided.

A pair of upper rollers facing the upper side of the guide rail and a pair of lower rollers contacting the lower side of the guide rail when the upper roller is separated from the guide rail are provided on the side surface of the moving plate. As the movable plate moves up and down, either the upper or lower roller comes into contact with the upper or lower side of the guide rail.

On the other hand, the movable plate is pivotally supported on the upper end of the piston rod of the first air cylinder, whose lower end is pivotally supported on a fixed part such as a frame, and the movable plate is pivotally supported on the upper end of the piston rod of the first air cylinder, and the lower end is pivotally supported on a fixed part such as a frame. The movable plate can be moved up and down.

Further, the other end of a second air cylinder whose one end is pivoted to a fixed part such as a frame is pivoted to a fixed part to the first air cylinder, and the compressed air is taken in and discharged from the second air cylinder. Accordingly, the first air cylinder is made swingable around its lower end.

Furthermore, rope conveyors are arranged on both sides of the moving plate, and the left and right sides of the rope conveyor are arranged on both sides.
The upper sides of the pair of ropes are located above the upper end of the movable plate that has descended as the first air cylinder contracts.

(Function) When, for example, a printed circuit board is to be taken in or taken out of a case using the plate-shaped article dispensing device of the present invention configured as described above, the piston rod of the first air cylinder is first contracted to lower the movable plate. With the upper roller supported on the side surface of the movable plate in contact with the upper side of the guide rail, the second air cylinder is contracted to move the movable plate toward the board housed in the case.

When the movable plate is moved toward the substrate in a lowered state in this manner, the folded piece formed at the upper edge of the distal end of the movable plate enters the lower side of the end of the substrate.

Once the folded piece has entered the lower side of the edge of the board, extend the piston rod of the first air cylinder to raise the movable plate, and move the lower roller supported on the side of the movable plate to the lower side of the guide rail. Bring it into contact.

When the movable plate is raised until the lower roller contacts the lower edge of the guide rail, the folded piece formed on the upper edge of the tip of the movable plate engages with the bent edge formed on the lower edge of the board. do. Further, in this state, the upper end of the folded piece is located above the upper side of the rope conveyor disposed on both sides of the moving plate.

From this state, by sucking and discharging compressed air into the second air cylinder, the piston rod of the second air cylinder expands and contracts, and the first air cylinder swings.
When the movable plate is retracted from the case, the substrate having a bent edge at its end that is engaged with the folded piece at the end of the movable plate is pulled out from the case.

When the board is completely pulled out from inside the case onto the rope conveyor, the piston rod of the first air cylinder is shortened and the moving plate is lowered until the upper roller contacts the upper side of the guide rail, and the board is pulled out over its entire length. The rope is brought into contact with the upper side of the rope conveyor.

Through this operation, the board moves away from the case on the rope conveyor and is fed into an automatic mounting device that mounts components such as IC chips.

By reversing the circulation direction of the rope during the mounting process, the board on which the predetermined parts have been mounted by this automatic mounting device is moved close to the case by a rope conveyor that moves in the opposite direction to that in the above case. The moving plate is kept in the lowered state during this time.

When the trailing edge of the board sent toward the case by the rope conveyor (the edge farthest from the case) passes over the folded piece of the moving board, the first air, which had been shortened until then, The piston rod of the cylinder is extended to raise the movable plate so that the front surface of the folded piece and the rear edge of the substrate face each other.

Next, the first air cylinder is swung by expanding and contracting the piston rod of the second air cylinder, and the movable plate is moved toward the case while bringing the front side of the folded piece into contact with the rear edge of the board. and push the board into the case.

Thereafter, the above-described operations are repeated, all the boards housed in the case are sent to the automatic mounting device, parts are mounted, and the boards are stored in the case again.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.

Figures 1 to 4 show an embodiment of the present invention. Figure 1 is a vertical side view of the teller device, Figure 2 is a view seen from the right side of Figure 1, and Figure 3 is the same as Figure 2. The view seen from the left, FIG. 4, is a plan view.

In the case of this embodiment, two movable plates for taking the board 1 in and out of the case 2 are provided, one for pulling out and one for pushing.

Guide rails 3 are installed on both sides of a guide rail 3 that is disposed horizontally behind a case 2 in which a plurality of boards 1, 1 are stacked vertically with a space between them. Moving plates 4a and 4b that move in the horizontal direction along 3 are provided, respectively, and folding pieces 5a and 5b are formed on the upper edge of the tip of each moving plate 4a and 4b, respectively.

Further, a pair of upper rollers 7, 7 and a pair of lower rollers 8, 8, which face the upper side of the guide rail 3, are supported on the side surfaces of each of the movable plates 4a, 4b, respectively, so as to be rotatable about a horizontal axis. ing. The distance between the lower end of the upper rollers 7, 7 supported on each movable plate and the upper end of the lower rollers 8, 8 is made larger than the height of the guide rail 3, so that the upper rollers 7, 7 are connected to the upper side of the guide rail 3. When the lower rollers 8, 8 are in contact with the lower side of the guide rail 3, the lower rollers 8, 8 move away from the lower side of the guide rail 3, and when the lower rollers 8, 8 are in contact with the lower side of the guide rail 3, the upper rollers 7, 7 move away from the lower side of the guide rail 3.
I try to keep it away from the top of the screen.

The movable plates 4a and 4b, which support both the upper and lower rollers 7 and 8 on their sides, are connected to the piston rods 10a and 10b of the first air cylinders 9a and 9b, respectively.
The first air cylinder 9a,
Each moving plate 4
a and 4b are movable up and down within the range in which the guide rail 3 can move between the upper and lower rollers 7 and 8. The lower end portions of each of the first air cylinders 9a, 9b are pivoted to a frame 11 fixed to a factory floor or the like, and are swingable about the lower end portions.

Further, the other ends of the second air cylinders 12a and 12b, which have one end pivoted to the frame 11, are pivoted to arm portions 17a and 17b fixed to the base ends of the first air cylinders 9a and 9b, respectively. are doing. Therefore, either second air cylinder 12a, 12b
By sucking and discharging compressed air, either of the first air cylinders 9a, 9b can swing around its lower end.

In this way, the first and second air cylinders 9a, 9
Rope conveyors are arranged on both sides of two movable plates 4a and 4b which are movable up and down and horizontally movable along the guide rail 3 by means of movable plates 4a and 4b. That is, pulleys 15, 15 are supported on horizontal shafts 14, 14 provided at both front and rear ends of the outer surfaces of horizontal mounting plates 13, 13 fixed on both sides of the moving plates 4a, 4b, respectively. ,1
Endless ropes 16, 16 are stretched around the ropes 5, and the upper sides of each rope 16, 16 are pushed upward by a push plate 19.

The upper sides of the ropes 16, 16 of the rope conveyor provided in this way are connected to each movable plate 4a, 4b when the movable plates 4a, 4b are lowered as the first air cylinders 9a, 9b contract. It is positioned above the upper edges of the folded pieces 5a and 5b that have been formed.

When loading and unloading the printed circuit board 1 from the case 2 using the plate-like article storage device of the present invention configured as described above, first, either of the piston rods 10a, 10b of the two first air cylinders 9a, 9b is pressed. is also contracted to lower the two moving plates 4a, 4b, and the upper rollers 7, 7 supported on the side surfaces of each moving plate 4a, 4b are brought into contact with the upper side of the guide rail 3. Next, with both movable plates 4a and 4b in a lowered state, the piston rod of one second air cylinder 12a, one end of which is pivoted to an arm 17a fixed to one first air cylinder 9a, is contracted. ,
The first air cylinder 9a is swung counterclockwise in FIG.
a to the left in FIG. 1 along the guide rail 3 toward the board 1 housed in the case 2.

By moving the movable plate 4a toward the substrate 1 in the lowered state in this way, the movable plate 4a
When the folding piece 5a formed on the upper edge of the tip of the first air cylinder 9a enters the lower side of the end of the substrate 1, the first air cylinder 9a having the movable plate 4a having the folding piece 5a pivoted on the upper end thereof is moved. By extending the piston rod 10a, the movable plate 4a is raised, and the lower rollers 8, 8 supported on the side surface of the movable plate 4a are raised.
is brought into contact with the lower side of the guide rail 3.

When the movable plate 4a is raised until the lower rollers 8, 8 come into contact with the lower side of the guide rail 3 in this way,
The folding piece 5a formed on the upper edge of the distal end of the moving plate 4a engages with the bent edge 18 formed on the lower edge of the substrate 1, and the upper end of the folding piece 5a forms on the upper edge of the moving plate 4a. It is positioned above the upper sides of the ropes 16, 16 of the rope conveyors arranged on both sides. However, in this state, the piston rod 10b of the other first air cylinder 9b remains in the contracted state, and the other movable plate 4b is held in the lowered state, and the The upper end edge of the folding piece 5b is positioned below the upper side of the rope 16 so that the folding piece 5b does not interfere with substrate movement during the next substrate drawing process.

From the state in which the folding piece 5a of one movable plate 4a is locked to the bent edge 18 at the end of the board in this way,
By sucking and discharging compressed air into one of the second air cylinders 12a, the piston rod of the second air cylinder 12a is extended, and one of the first air cylinders 9a with the movable plate 4a provided above is shown in FIG. When the movable plate 4a is retracted from the case 2 along the guide rail 3 by swinging clockwise, the folding piece 5a on the upper edge of the end of the movable plate 4a engages with the 1
One board 1 is pulled out from the case 2.

As the movable plate 4a moves horizontally due to the swinging of the first air cylinder 9a, the board 1 is moved from inside the case 2 to the ropes 16, 16 constituting the rope conveyor.
When it is completely pulled out to the top, the movable plate 4a
The piston rod 10a of the first air cylinder 9a that was driving the air cylinder 9a is contracted, and the moving plate 4a is lowered until the upper rollers 7, 7 supported on the moving plate 4a come into contact with the upper side of the guide rail 3. As the movable plate 4a descends, the lower surface of the board 1 pulled out from the case by the movable plate 4a is moved along its entire length by the rope 16, which constitutes a rope conveyor.
It abuts on the upper side of 16.

At this time, each rope 16, 16 has its upper side connected to the case 2.
Since the board 1 is circulating in the direction away from the case 2, by contracting the piston rod 10a and lowering the board 1, the board 1 moves in the direction away from the case 2 on the ropes 16, 16 forming the rope conveyor. It is sent to an automatic mounting device that mounts parts such as IC chips.

The board 1 on which predetermined parts have been mounted by this automatic mounting device is moved by the ropes 16, 16 of the rope conveyor that circulates in the opposite direction to the above case.
It will be sent back close to case 2. During this sending back, both of the two movable plates 4a and 4b are maintained in a lowered state.

In this way, the board 1 with the parts attached is sent back to the vicinity of the case 2 by the rope conveyor, and the rear edge of the board 1 that is sent back (the edge on the side far from the case 2,
Right edge of Figure 1. ) passes above the folded piece 5b of the movable plate 4b pivoted to the upper end of the piston rod 10b of the other first air cylinder 9b, the other first air cylinder, which had been shortened until then, Extend the piston rod 10b of 9b,
The movable plate 4b, which had been lowered until then, is raised, and the front side of the folding piece 5b provided on the movable plate 4b and the rear edge of the board 1, which has been sent back on the rope conveyor with parts mounted, are removed. Make them face each other.

When the front surface of the folding piece 5b provided on the movable plate 4b and the rear end edge of the board 1 are opposed to each other, a second air cylinder whose one end is pivoted to an arm portion 17b fixed to the other first air cylinder 9b is opened. By contracting the piston rod of the air cylinder 12b, the other first air cylinder 9b is swung clockwise in FIG. 3, and the piston rod 10 of this air cylinder 9b is
The front surface of the folding piece 5b of the movable plate 4b, which is pivotally supported on the upper end of the movable plate 4b, is brought into contact with the rear edge of the board 1 on which the component is mounted, and the movable plate 4b is further moved toward the case 2. Then, push the board 1 into the case 2. At this time, the movable plate 4a used for pulling out the board 1 with no components attached remains in a lowered state.

Thereafter, the above-described operations are repeated, all the boards 1, 1 housed in the case 2 are sent to the automatic mounting device, parts are mounted thereon, and the boards 1, 1 are stored in the case 2 again.

In the above embodiment, two sets of first and second air cylinders are provided, and the work of pulling out the board 1 from the case 2 and the work of pushing the board into the case 2 are performed using separate air cylinders. I try to do it by leaning over. This is because when pulling out and pushing in the same air cylinder, the position where the board with components attached is pushed in is higher than the position where the board without components was stored, due to the fold formed on the movable plate. This is because the depth is the sum of the thickness of the upright piece and the thickness of the bent edge formed on the board.

However, if it is not necessary to strictly control the storage position of the board with components mounted thereon, the drawing operation and the pushing operation may be performed by the same air cylinder.

c. Effects of the invention Since the device for dispensing and discharging plate-shaped articles of the present invention is constructed and operates as described above, it can be manufactured at low cost without using any particularly complicated mechanism, and moreover, it can be manufactured at low cost without using any particularly complicated mechanism. You can reliably carry out the collection and delivery work.
