Description

[Detailed description of the invention] Tool parts attached to folding cylinders, mouth cylinders, etc. in paper processing machines, such as cutters, folding blades, rubber stands 'f: fc 6'1
Conventionally, needles, etc. were attached directly to each cylinder built into the processing machine, so replacing and installing the same tools required position adjustment.
It is carried out on board the aircraft.

Tool conversion in such a processing machine is 0th t m Jtt
The working environment was poor, work efficiency was low, and it was difficult to provide accurate training. It is considered that the work time is minimal compared to that, and it is mainly a tool change by an expert.
The current situation is that there is no adjustment.

However, as mentioned above, it is true that the cracking rate is low and it is difficult to fully utilize the cutting power, so it is not just because of ρ, but because it is necessary to use a skilled person to change tools. When changing jobs, change tools, IO! For leverage adjustment,
This results in giving the machine idle time, which is not economical.

The present invention was devised in view of the above-mentioned defects in conventional equipment, and its main part is to partially replace cylinder parts such as folding cylinders and mouth cylinders that are assembled into processing machines. The replacement block can be installed and removed as a replacement block, and the installation and position adjustment of tools on the replacement block carried outside the aircraft can be carried out at a specific location prepared for this purpose using equipment such as assembly tools and sheath density measuring devices. After checking that it occupies the specified position, assemble and secure it.

The mutual positional relationship between the tool block and the cylinder is set in advance so that it is always constant when fixed to the block cylinder. When the installed exchange block is installed on the cylinder, the point is that the tool eventually assumes a predetermined positional relationship or adjusted position with respect to the cylinder.

Since the present invention has the above-mentioned configuration, it is necessary to set it on a specific tool tray replacement block in advance. Depending on the type of machining, remove the replacement block from the cylinder on the machine and place all the tools prepared in advance in the specified positions. By attaching the replacement block attached to the holder, it does not require much work time to change the tool, and the installation is relatively easy, that is, the tool can be replaced without requiring special skill. Since a high tool mounting position can be obtained, it is possible to improve the workability of the tool and the machine, and therefore it can be expected that the operating rate of the processing machine will be improved.

One embodiment of this invention will now be described with reference to the accompanying drawings.

Fig. 1 is a perspective view of a cylinder with a tool changing block according to the present invention, where ■ is a cylinder, which is usually formed using Yohko Materials Co., Ltd., and whose center is supported by a bearing provided in the frame of a JTL processing machine. Then, when the tool 5 is installed inside the processing machine and rotates by an appropriate means, the paper is processed according to the tool using the tool 5 installed on the circumferential surface of the norinda. i:
Iso parts, 2nd floor, a U-shaped groove drilled in the cylindrical surface of the cylinder, extending along the generatrix of the cylinder, an L-shaped cross section kWL with an external shape that is almost the same as PH, and a cylindrical block that is almost the same length as the cylinder. (or called a block) 3 When fully fitting and fixing,
The mutual positional relationship between the two is specified based on the taper pin or the pin or key groove that fits into the reamed hole. Of course, depending on the type of tool, there are tools in which an error in the mounting position of the tool in the direction of the cylinder axial force does not pose an obstacle to machining, so the fixed positioning mechanism of the replaceable block is not necessarily essential. 4r/'i, Hexagonal socket head bolts (or mounting screws) for fitting and fixing the above replacement block 3 into the cylinders 1 and 12. Usually, a plurality of these are provided alternately in the longitudinal direction of the block. When the bolt is screwed in, the head will be embedded in the bottomed hole drilled in the block.

The replacement block 3 can be removed from the cylinder 1 by removing the mounting screws 4r and then press-fitting a tapered member between it and the bottom of the U-shaped groove 2. In addition, although the work of attaching or removing the block is done on a processing machine, the work is not cheap, so it is easy to use in comparison.

It becomes easy.

5rri, with the installation tool, the folding blade is attached in this implementation row,
Is the folded 9-blade 5 its base? It is fixed to the four parts of the replacement block 3 with a plurality of mounting screws 6.

The relative positional relationship between the replacement block 3 and the folding blade 5 is determined by the screw 6.
Before screwing, slight adjustments can be made, and the leg walls are fixed in advance so that the height of the blade matches the predetermined position, that is, the optimum height for processing.

Of course, what is the rental fee for the most suitable Takaishi for machining, including the type of machining material of the 9-blade 5, which is the cylinder axial force applied when 1 ash per 10 m2 of cylinders of 3 blocks is applied? The work of adjusting and fixing fi' to the broken block 3 is done carefully using a measuring instrument and tools based on the above-mentioned rental fee.

Furthermore, the position adjustment can be carried out by removing the cylinder I on the replacement block 32 and bringing it to a place where the work environment has been adjusted, making it extremely easy to make highly precise settings. Become.

In addition, the plane of the folding blade 5 is cylinder 4i111 +l/J
In other words, the parallelism with the generatrix around the cylinder 7 is the parallelism between the cylinder groove 2 and the replacement block 3.
Since this depends greatly on the accuracy of the machining, if the cylinder is carefully machined during the manufacturing stage, the folding blade 5 can be screwed onto the exchange block 3 and the position will be naturally accurate. It becomes something that occupies.

As mentioned above, the position of the folding blade 5 should be adjusted in the environment outside the processing machine and in a place with good footing where 71≧Measuring instrument 1 and assembly tools etc.
The replacement block 3, which has 5 position-adjusted folding blades, can be fitted and fixed into the groove 2 drilled in the cylinder 1 to perform the tool replacement adjustment. Improves and simplifies the work on the processing machine with conventional scaffolding and poor environment, improves the work efficiency of the tool owner, and enables relatively high-precision adjustment, ultimately improving the operating efficiency of the processing machine. r can be expected.

The above-mentioned tool changing means is not limited to folding blades, but can also be applied to cutters, needles, and paper processing tools with the same effect.

Furthermore, the shape of the groove 2 drilled in the cylinder 1, the 0-face shape of the replacement block that fits into the groove 2, and the means for fixing the tool are not limited to those of the above-mentioned implementation, but are part of the structure. ? Even if the substitution is made with other well-known techniques, as long as the object and constituent elements of the present invention are met, the technical scope of f, f'1. become something that
