Abstract

The elevator for a finisher's slab in accordance with the present invention is constituted of a pair of slide plates (4, 5) having a substantially wedge-shaped section between a base (2) and a rod (1c) of a finisher's slab (1) wherein one of the sliding plates (4) is slid relative to the other (5) so that the slab (1) is moved up from and down to the base (2). Therefore, in comparison with an elevator constituted of chains, sprockets, etc., the present elevator does not have any play and can move up and down the slab (1) with a high level of accuracy. Since each rod (1c) of the slab (1) is received by the base (2) through first and second slide plates (4, 5), the present elevator can sufficiently bear a large load and has high load resistance. Since there is no scattering of metal powders or grease that occurs when using chains and sprockets, contamination of an article to be printed can be prevented effectively.

Technical field

SUMMARY OF THE INVENTION The present invention is directed to an elevating and lowering device for printing and setting, which raises and lowers a printing set on which a printing rest is placed with respect to a base.

Technology background

Conventionally, in general, an object to be printed is placed on a printing surface and printed with a printing roller or the like, and a predetermined printing is performed. For example, a thin film printing method is used as shown in Japanese Patent Publication No. 58-1816S2. When the printing is performed, if the thickness of the printing medium is different, the fixed boat is moved up and down by S It is necessary to adjust the height with high accuracy

Conventionally known as this elevating device, a downward elevating guide rod is projected and fixed to a set 4 PB, and a screw portion is formed in each of the sigma-dods. A spar socket is attached to the screw part, and a chain is attached to the respective s block, and each rod is configured to be supported on the base through a sprocket. The sprocket was rotated by the movement of the ground, and the rod was moved up and down to descend a fixed ft.

However, in the above configuration of the “car-bearing” device, it is necessary to play the sound between the squaroket and the chain. For this reason, the accuracy is as high as about 0.01 fiber. JS said that it was difficult to raise and lower the printing surface, and that the surface of the printing medium became dirty due to scattering of gold R powder and grease generated when the chain and sprocket were joined. .

In order to solve the problem, the screws of each rod above It is conceivable that a ball screw or the like is assembled in Tokyo and the nut of each ball screw is rotated by a synchronous drive such as a stepping moda or a servomotor so that the above-mentioned rods are simultaneously moved up and down.

However, in the above-mentioned constant-R device, if a high-precision ball screw is used to move the rod up and down extremely, the entire ball screw is reduced in size, and for example, a load of several hundred kg is regulated. When this function is applied, each rod can no longer be supported by a bow / thread, and there is a large 18!

Accordingly, it is an object of the present invention to solve the above-mentioned problems, to be able to raise and lower the settling with high accuracy, to be superior in load resistance, and to be subject to damage. An object of the present invention is to provide a stamping and setting device that can effectively prevent contamination of a new body.

DISCLOSURE OF THE INVENTION

In order to achieve the above object, according to the present invention, a pair of movements having a substantially wedge-shaped cross section is provided between a base and a rod having a constant S, and one of the slides is used for the other slide. The table is configured to be moved up and down with respect to the base by being moved with respect to the root. An i fi motion having a sloping surface inclined at a constant angle, and a lower surface on which the K is placed on the first S »plate and the above-mentioned set up and down elevating rod is faced. A second slide having an inclined surface inclined at the same angle as the inclined surface of the first moving plate and having the inclined surface freely drawn in a movable manner; and (2) The seeding member is moved along the upper surface of the base, and the projecting member and the first sliding member which are locked and guided freely along the vertical direction are combined with the base and the second plate. Out to 囿 The slope of the first sliding plate, the inclined surface of the second sliding plate, the lower surface of the first sliding plate, and the upper surface of the base are directly connected to each other. In addition to making it movable by contacting it, it is also possible to use a movable guide member between the inclined surfaces and on the surface, for example, by using a bearing to arbitrarily move freely. .

In the above-described tank formation, the driving device is driven to slide the first S-axis against the upper surface of the base and the second slide, and the wedge is formed from the second slide and the base. The first sliding plate is moved along the horizontal direction so as to be pulled out, and the second sliding plate is lowered by the guide of the building material to lower the boat. Conversely, the boat drive device is reversely driven to move the first seeding plate in the reverse direction along the horizontal direction, and the wedge between the second sliding plate and the base is easily driven. The first slide is moved as described above to raise the second slide, and the above-mentioned constant is raised through each of the lots.

According to the refinement described above, the set can be raised and lowered smoothly and with high precision. Therefore, as in the case of the chain and the throttle, there is no play, so the accuracy is high, for example, O. Olmi It can be moved up and down by any degree. In addition, since each rod of the surface plate is received by the base via the first sliding plate and the second rail, a large load can be sufficiently received and the load resistance is excellent. Since there is no metal powder or grease like a chain and a sprocket, contamination of a printing medium can be effectively prevented.
