Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a substrate receiving device, and more particularly to a printed wiring substrate receiving device.

[Conventional technology]

Conventionally, as shown in FIG. 3, a substrate receiving apparatus of this type conveys a substrate 2a carried out from the previous step by a conveying roller 2b,
When the substrate end reaches the rear end of the substrate reversing bar 2c, the substrate 2a is vertically rotated, and the pusher 2d is rotated.
Push the edge of the substrate with and lean the substrate on the stocker 2e. In this state, after the substrate reversing bar 2c and the pusher 2d are moved to the original state, the stocker 2e performs the operation of retreating according to the thickness of the substrate and the operation of sequentially receiving the substrate.

[Problems to be solved by the device]

Since the above-mentioned conventional substrate receiving device is a single stocker, it is difficult to take out the received substrate with an arbitrary number of substrates, because the previous process must be stopped or an interval corresponding to the work is required when the substrate is taken out. There is a drawback that

An object of the present invention is to provide a substrate receiving device that eliminates the above-mentioned conventional drawbacks.

[Differences from the Prior Art of Invention]

In contrast to the above-described conventional substrate receiving device, the substrate receiving device of the present invention performs the preceding process by simultaneously carrying out the substrate received by the stocker performing the forward, backward, and rotating operations of the cross shape and preparing for the next reception. Without affecting
The difference is that the received substrates are carried out with an arbitrary number of substrates.

[Means for Solving the Problems]

In order to achieve the above object, in the substrate receiving device of the present invention, the substrate is leaned against the arms arranged in a cross shape around the axis of rotation and stocked, and the arms are angularly rotated and reciprocally moved in the front-back direction. A rotary stocker for transferring and receiving, a reversing bar provided at a forward position of the rotary stocker, and a reversing bar standing up in a posture of leaning a substrate loaded in a horizontal posture on the arm of the rotary stocker, and a reverse position of the rotary stocker, The rotary stocker has a conveyor that receives a substrate laid down in a horizontal position by the angular rotation of the arm and carries the substrate out.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, according to the present invention, a substrate is leaned against an arm 1h arranged in a cross shape around a rotating shaft 1g so as to be stocked, and the substrate is transferred by angular rotation of the arm and reciprocal movement in the front-back direction. Rotating stocker 1e for performing
e, a reversing bar 1c, which is provided at a forward position of the rotating stocker 1e, and which raises the substrate loaded by the feed roller 1b in a horizontal posture against the arm of the rotary stocker 1e. The stocker 1e has a conveyer that receives a substrate laid down in a horizontal posture by the angular rotation of the arm and carries the substrate out.

In the rotary stocker 1e, arms 1h arranged in a cross shape around the rotary shaft 1g are arranged in a comb shape at a constant pitch in the axial direction of the rotary shaft 1g. As shown in the figure, the rotary stocker 1e has one shaft. A cross-shaped arm 1h is fixed to 1g in a comb shape, a slide holding mechanism 1i is provided at both ends of the shaft 1g, and a forward / backward feeding mechanism such as a motor and a rotating mechanism 1j are connected. The substrate supporting surface of the arm 1h is gently tilted backward so that the substrate can be leaned against and easily stocked.

The pusher 1d is arranged in a comb-shaped space between the adjacent arms 1 of the rotary stocker 1e, and fixed to a support 1k having a rectangular cross section with sliding mechanisms at both ends, and is moved forward and backward by a cylinder or the like. Do. Further, an inversion bar 1c is provided at an appropriate interval in the height direction with respect to the substrate holding horizontal plane of the pusher 1d and the rotary stocker 1e, and the inversion bar 1c is an axis provided with a rotation support mechanism 1l at both ends. ,
A plurality of flat plates with rectangular cross sections are arranged side by side and fixed, and this shaft is repeatedly rotated about 100 ° by a cylinder or the like. The reversal bar 1c is provided between the disc-shaped rollers of the feed roller 1b, the substrate 1a transport surface, and the feed roller 1b.
It is located in the space created by the shaft. Further, the conveyor is provided with a substrate unloading belt 1f in the comb-shaped space of the rotary stocker 1e, and a belt is fed by a motor or the like to carry out a carrying operation.

Next, the operation of the substrate receiving device of the present invention will be described with reference to FIGS.

The substrate 1a carried out in the previous step is conveyed to the exit end of the reversing bar 1c by the feed roller 1b, and a photosensor or the like is provided at this position to detect the presence or absence of the substrate 1a. Board 1a
Is detected, the substrate 1a is rotated by rotating the reversing bar 1c.
Is erected and leaned against the arm 1h of the rotary stocker 1e, and the pusher 1d pushes the lower end of the substrate 1a toward the rotary stocker 1e to align the substrates 1a. After this,
The reversing bar 1c and the pusher 1d return to the origin position.
Further, the thickness of the leaning substrate 1a is detected by a photo sensor or the like, and the rotary stocker 1e is moved backward so that the position of the substrate 1a received last becomes constant. The carry-out operation is performed according to the arbitrarily set total thickness or the total number of the substrates 1a that are repeatedly leaned against the above operation.

In the carry-out operation, the rotary stocker 1e is retracted and fed to a position where it does not interfere with the pusher 1d and the reversing bar 1c, and thereafter, the arm 1h of the rotary stocker 1e is angularly rotated, and the received substrate 1a is laid down in a horizontal posture to transfer the substrate. The substrate 1a is transferred onto the belt 1f and is fed by the substrate conveying belt 1f.
Carry out. Further, the rotary stocker 1e moves forward to a fixed position.

[Effect of device]

As described above, the present invention makes it possible to carry out the received substrate in an extremely short time by using the substrate stocker in the rotation system, and it is not necessary to stop the previous process. Further, there is an effect that it can be carried out in an arbitrary number of substrates or an arbitrary unit of substrate thickness.
