Abstract

PURPOSE:To prevent productivity from reduction in a plate material supply unit for a working unit such as printed substrate printing unit by replenishing the plate material from a replenishing position at the lower side of a supply position without stopping the supply unit. CONSTITUTION:When an empty bed plate 14 of a supply unit 2 is moved to a position P5 to screen a light beam to a detector 101, a compression air path for an air cylinder 99 is changed over to move a piston rod 100 to an initial position. At the same time, a motor in a lift is activated to drive a chain 13 circumferentially, and lift the bed plate 14 on which a plurality of substrates 3 furnished below the supply unit 2 are laminated to a position regulated by a pair of detectors 74, 75. Thus, the substrates 3 can be simply replenished without stopping the running of the supply unit 2 so that the substrates 3 are accurately continuously fed one by one to a printing unit by the supply unit 2 to produce high quality printed substrates.

Description

Detailed Description of the Invention Technical Field The present invention relates to an apparatus for processing a number of plate materials one by one starting from the upper one by a feeding device while intermittently raising a base plate formed by stacking a large number of plate materials in the vertical direction. (This article relates to a method and apparatus for replenishing the supply device 4kl with plate material, particularly in a supply device for handling ∆ that feeds the material to the 11υ.

Prior Art Conventionally, for example, in a board supply device for a pressurizing device such as a printed circuit board printing device, the substrates stacked on the base plate 1 and 2 are all stacked on the printing device 1 side. I was sent to that platform (Jy is 1 town 7.c.
11.5. Stop the supply device and stack the substrates on the table & l)・1〆1 ura, or take out the empty base plate and place a new base plate with the substrates stacked on it. The car was running at 11 a.m. after installation.

Therefore, when replenishing the substrates, it is necessary to stop the operation of the printing device that is linked to the supply device, which leads to a decrease in work efficiency. In other words, if the supply of substrates stops, all the lines, including the next process, will be stopped, reducing productivity. This was a significant decrease. In addition, in this God's Pudding 1 board printing device, printing for J and (-11j is generally performed continuously in multiple 1. The board stopped at about 1. in the middle of being printed (i?), the degree of dryness of the printed area changed greatly, resulting in a decrease in quality.

Therefore, especially in the case of a supply device for the board 41 to a processing device that cannot be stopped mid-operation, such as the printed circuit board printing equipment fi'7 shown here, it is necessary to stop the supply device. There has long been a desire for a method that can fill the plate material to #Ii without the need for oxidation.

Point 1 of the Invention This invention was developed in order to cope with the above-mentioned desire, and its point 1 is to stop the [J" (C)1
An object of the present invention is to provide a replenishment method and apparatus for a supply device for plates 4A, which can be replenished to 1 t, and can continuously supply plates 4J one by one to a processing device using a lining device.

DETAILED DESCRIPTION OF THE INVENTION In order to achieve the above-mentioned objects, the present invention comprises a large number of plates 4.
A is stacked between the upper and lower parts, and the base plate 4A is intermittently raised, and the plate 4A is fed by the feeding device.
In a sheet supply device that feeds two sheets one by one to a processing device, the plywood placed at the feeding position corresponding to the feeding device is raised beyond a predetermined height. When the board material on the white base is running low, a new plywood board made by laminating a large number of plywood sheets is carried from the replenishment position on the lower side of the supply position to the lower part of the supply ii'rF position, and

-Si1- A device (1♂) is constructed.

Above the lifting device, guide rods 27 are installed on the inside of both side frames 8, and between both guide rods 27, a planar cross-shaped support frame 28 is inserted through a sliding body 29 in the left-right direction. It is supported by oil for movement. A support piece 30 is supported at both left and right ends of the support piece 28 via a support block 31 at a position adjustment of 13ij ++J in the left-right direction and the front-back direction. The f>iJ rear end portions of both support arms 30 serve as suction devices for suctioning the substrates 3 of the base plate 141 one by one and feeding them to the printing device 1 side. The positions of S3 and S4 are adjusted between the front and rear via the support pieces 32.

Each version of the j1f device S1 to S4 is shown in Figs. It consists of a suction part 35 fixed to the lower end of the rod 34. An inner cylinder 37 is inserted and supported on the outside of the suction part 35, and inside the inner cylinder 37 is inserted and supported by the inner cylinder 37. 1. ``Panel 3B is taken 1i-f.

And, the suction cup 3B described in 1jiI is the outer cylinder 361.
Due to the action of the spring 39 provided here, the spring 39 at the lower end of the outer cylinder 36 is held in the downward position where it is regulated, and suction air acts on the suction part 35 via the vibrator 41. The ribs are designed to be raised against the action of a spring 39 in a state in which the substrate 3 at the end of the rnJ mark is sucked.

Further, as shown in FIG. 8, the suction member 35 of each suction device 81 to S4 is connected to a suction air source 42 such as a vacuum pump through a suction air path including the vibrator 41, and the suction member 35 of each suction unit 35 is Opening/closing valves 43a, 43b, 43c, and 43d are provided to operate each of the suction valves 43a, 43b, 43c, and 43d separately.

Further, the air cylinders 33 of each adsorption device 81 to S4 are connected to a compressed air source 44 such as a compression pump via a compression Y and an air passage.
The air passages of each air cylinder 33 are provided with openings 145a, 45h, 45c, and 45d for operating the links 33 separately.

In this embodiment, after the opening/closing fp43a-43d for the adsorption fXH) J' 35 is opened and opened according to FIG. The on-off valves 45a to 45d are controlled a11 to open, and each adsorption device white 81
- The opening/closing valves of S4 are treated as one unit, and the timing at which they start operating can be changed. In this control circuit, the ROM 474, which constitutes a microcomputer together with the CPU 46, is used to control the programs that control the CPU 46, as well as the different operation start timings of the adsorption devices 81 to S4 (actually, the operation start times for each of the on-off valves 43a to 43d, 45a). ~4
A plurality of types of combination data (opening/opening timing of 5d) are stored, and the side frame 8

It is displayed at 9.

That is, in this embodiment, five types of combinations A to E are prepared to correspond to variations in the size, shape, thickness of the substrate 3, the degree of hole opening in the substrate 3, etc. As is clear from Fig. 7, type A is the pair of suction devices S on the left side.
1. S1 first operates, then the pair of adsorption devices on the right side S3. The species ViYF B shows the manner in which the pair of suction devices S1 and S3 on the rear side operate first, and then the pair of suction devices S2 and S4 on the 1''+iJ side operate. Similarly, type C is a mode in which Sl is activated first, 82 is activated after S4 is activated, and S3 is activated, and the type is 81.
