Description

The present invention relates to a power source for driving each part of the collating machine and a method for transmitting the power. The gear, belt, driving shaft, etc. in the power transmission path are subjected to elongation, twisting deformation, and gear transmission. Products manufactured by the collating machine with less disturbance of synchronism in each printing, processing device and paper feeding device part which is each driven part due to the gear teeth of the meshing part The present invention relates to a method for increasing printing and processing accuracy.

In the conventional apparatus, as shown in FIG. 5 of the conventional apparatus explanatory diagram, a printing apparatus, a crimping apparatus,
A set including a processing device such as a file punching device, a slitter device, a horizontal sewing machine processing device, a roll paper feeding device and a paper conveying device of a paper feed unit, and a post-processing device such as a folding machine is driven by the main motor 1. It was configured as follows.

Gear boxes 24, 25, 38, 39, 40 having output shafts at several positions on the drive shaft of each device portion on the drive side of a post-processing device unit such as a paper feed device unit, a processing device unit, or a folding machine. And the driving shafts 26, 37a, 37b, 37c are laid across the respective device parts so as to connect the input shafts of the gearboxes, and the power of the main motor is transmitted.

The power of the main prime mover transmitted to each device part by the drive shaft is transmitted to each part from the output shaft of the gear box disposed in each part via a gear and a transmission belt.

In the above-described conventional apparatus, each driven part includes a part having a large load fluctuation such as a horizontal sewing machined part, a folding machine crank part, and a swinging part of a printing part. Since it is connected to the drive unit, there has been a problem in that the load fluctuation is transmitted in a manner that prevents uniform and stable rotation without unevenness of each driven unit.

In addition, since the drive shaft is passed to each device part, the connection accuracy of each device frame and the drive shaft connection work are required, and the work efficiency in assembly, disassembly, maintenance, etc. deteriorates, and each feed such as a pin tactor and pin belt There was also a problem that required a phase adjustment mechanism between devices.

Furthermore, power is transmitted mainly by the belt in the light load part of the paper transport device, and when the impact and vibration load generated in the device part with a large variable load are transmitted, the belt is an elastic body. It is affected and prevents stable paper feeding. For this reason, there has also been a problem of causing a result of deteriorating the work position accuracy of each printing and processing apparatus on the paper.

Also, in the case of a collating machine that transports paper by engaging pins that are perforated for transport at both ends in the direction perpendicular to the paper flow of the transport paper, the holes that are perforated in the paper from the pin diameter Since the diameter is large, there is a gap between the pin for feeding and the paper hole, and if a generation factor such as a change in feed speed or vibration due to instantaneous impact force occurs, the paper conveyance becomes unstable, and the paper There was also a problem that printing and processing accuracy deteriorated.

Japanese Patent Laid-Open No. 11-254654 discloses a printing machine in which a printing cylinder is driven and controlled by a single drive motor to improve printing quality. However, in the case of a collating machine, a printing apparatus is used because of a pin feed system. Even if only the portion is controlled by a single drive motor, the accuracy error of the paper conveyance may be larger than that of the printing press, and the result of improving the accuracy could not be obtained. In addition, since the collating machine is a pin feed system, there is an established concept that there is a limit to the improvement in accuracy. It is intended to solve problems in these collating machines, improve product printing and processing accuracy quality, and improve workability and operability.

In the above apparatus, when the apparatus part other than the sheet conveying apparatus is driven by one motor, it is synchronized with the detection result of the rotation detector such as a rotary encoder provided in the driven part. Similar improvement results can be obtained by configuring the other single drive motor to be controlled. As a result, it is possible to remove the power transmission components from the drive source such as the gear box, the drive shaft and some of the gears and belts that existed in the conventional device, and the drive system of the device portion with large load fluctuation can be separated and independent. .

According to the collating machine of the first aspect of the present invention, the feeding accuracy of the paper conveyance is deteriorated due to the unstable rotation of the drive system due to the influence of the portion where the load fluctuation is large. It is possible to prevent the printing position and processing position accuracy with respect to the paper from being deteriorated.

The reduction in the number of driving shafts facilitates frame disassembly and reduction of the number of man-hours, and the phase adjustment between the sheet conveying devices can be set by a single motor control device, facilitating the adjustment work.
