Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for pulling up a discharge guide bar, which is used to simplify the work of taking out the objects to be collated discharged from the discharge port of a newspaper insert advertising collator. Regarding

[0002]

2. Description of the Related Art The applicant of the present application has disclosed in Japanese Patent Laid-Open No. 6-92536 that "a shelf board on which an advertising insert is placed and a roller device for carrying in the advertising insert are provided on the upper side of the machine. A guide for dropping the inserted advertisements into the lower part of the machine and its feeding roller device are provided, and on one lower side of the machine, a shelf board on which newspapers are placed, a roller device for carrying in them, and release of newspapers An adsorption opening device that opens the end side is provided, and an opening guide that opens and supports the open end side of the newspaper paper is provided at the bottom of the main body of the machine body, and it passes through the inside of the opening guide and is folded into the newspaper paper. In addition, a device for collating the folded advertisements with newspaper newspapers configured to send the folded advertisements with a carry-out roller device (hereinafter referred to as a newspaper folded advertisement collator) is proposed.

[0003]

In this way, in the morning and evening, the mechanization and labor saving of the work of collating various types of insert advertisements with newspaper newspapers delivered from newspaper companies to newspaper retailers are addressed. Although I got it, the following problems have been newly derived. As shown in FIG. 3 of Japanese Unexamined Patent Publication No. Hei 6-92536, a discharged guide bar formed by projecting in the vicinity of the discharge port of this machine is a material to be collated by the above-mentioned newspaper insert advertisement collating machine. Although it is stacked inside the storage case via the, the storage case is located near the floor surface, so the worker bends his waist and puts the appropriate amount of stacked objects on the stack. Work to hold and take out
Must be repeated.

In this respect, the "newspaper advertisement collating device" shown in FIG. 1 of JP-B-55-38922, JP-B-58-10.
No. 2533, FIG. 1 and Japanese Utility Model Laid-Open No. 58-154236, “Automatic Paper Feeding Device for Newspaper Advertising Collator”, and FIG. Even in the case of the "paper device", although the discharge guide bar is not disclosed, the collated objects stacked in the storage case must be held and taken out in an appropriate amount.

If the storage case itself is pulled up by a lifter device in order to easily perform the above-described work of collecting the objects to be collected, the work of taking out the objects to be collected can be simplified. A discharge guide bar for discharging and guiding the objects to be collated is formed at the outlet of the folding advertising collator, and the ejection guide bar is indispensable for stacking the conveyed collates in multiple layers. is there. Therefore, it is not possible to deal with it by just lifting the storage case itself with the lifter device.

Therefore, as a second best measure, a belt conveyor is installed in place of the storage case instead, and the articles to be discharged are stacked on the belt conveyor, and the belt conveyor is operated. By doing so, the objects to be collated are temporarily transferred laterally on the lift table of the lifter device, and the table is lifted from the floor surface to a position around the waist of the worker to take out the objects to be collated. I decided to deal with the simplification of.

However, the discharge guide bar is in contact with the upper surface of the objects to be stacked on the belt conveyor in contact with each other, and when the belt conveyor is rotated to transfer the objects laterally, The surface layer of the material to be collated may be caught by the discharge guide bar, which hinders smooth lateral transfer of the material to be collated.

[0008]

Therefore, in the present invention, in order not to cause a catching phenomenon when laterally transferring the objects to be collated on the belt conveyor, immediately before laterally transferring the objects to be collated on the belt conveyor, By raising the tip of the discharge guide bar, we proposed a device for raising the discharge guide bar that enables smooth lateral transfer. Specifically, in a collating machine in which a discharge guide bar of a material to be collated is formed to extend at the discharge port of a newspaper insert advertising collating machine, the collating machine discharges directly below the discharge guide bar. Install a belt conveyor for lateral transfer of collated objects to be stacked,
At the side end of the conveyor, a barrier box for the articles to be stacked on the conveyor is started up, and the front plate of the barrier box has a vertically long opening for guiding the tip of the discharge guide bar. In the barrier box, rotating pulleys are vertically spaced from each other, and coil springs are hung and supported at outer peripheral positions of the upper and lower rotating pulleys. The tip portion of the discharge guide bar is detachably engaged and supported, and the rotation pulley is rotated a half turn so that the tip portion of the discharge guide bar is engaged with the coil spring and pulled up.

[0009]

[Operation] The number of copies or the set number of objects to be collated, which are set in advance at the preset time, are carried out from the outlet of the newspaper folding advertising collator to the belt conveyor via the ejection guide bar and piled up. Then, the machine collating work is temporarily stopped.
When it senses this, the upper and lower rotary pulleys installed inside the barrier box start to rotate, the tip of the discharge guide bar is engaged between the coil springs hung on the rotary pulley, and the coil is rotated by half rotation of the rotary pulley. When the spring is pulled up, the ejection guide bar is pulled up and temporarily stopped. As a result, a space is formed between the surface layer of the material to be collated and the discharged discharge guide bar. When it detects that the discharge guide bar has been pulled up, this time the belt conveyor of the conveyor device is driven to laterally transfer the objects to be stacked on top of it and transfer the objects to the lifting table of the lifting device. Place and transport. Then, the lift device drives the motor to transfer the objects to be transferred, which are transferred onto the lifting table,
By raising and moving to a position around the waist height and holding the worker in a standing posture, the work load at the time of taking out the objects to be collated is significantly reduced. Also, after the material to be collected is transferred to the lifting table of the lift device, the rotary pulley provided inside the barrier box makes a return rotation and is engaged with the coil spring at the appropriate position to lift the discharge guide bar. Is removed from the coil spring, dropped downward, and again faces directly above the belt conveyor, whereby the articles to be discharged from the newspaper folding advertisement collator are stacked again.
