Description

[Detailed Description of the Invention] The present invention relates to a file holder restraining device for a file machine, and more particularly to a file holder restraining device for a file machine that moves a carrier storing a file holder and automatically extracts a desired file holder.

To take out a desired file holder with a conventional file machine, the carrier that contains the file holder is stopped at the exit position, and then a clerk searches for the desired file one by one, starting from the end. It is a human work. Therefore, the search takes time, and it is difficult to extract a large number of file holders in a short period of time. Also, the conventional single 1
Since the sheet extraction device has one rack and one extraction mechanism, even if stacked, only 4 or 5 units can be stacked, and they must be used horizontally, requiring a large installation area. Since the height fluctuates, it not only makes the office worker tired, but also increases the overall price.

The present invention eliminates both of the above drawbacks and provides a file holder restraining device that ensures selective operation of an automatic extraction device in order to obtain a highly useful file machine that can reliably take out a desired file holder. The purpose is to In other words, the carrier having a plurality of carriers containing a desired file holder is moved to an outlet, and the selection claw of the stored file holder is selected and engaged by an automatic extraction device separate from the carrier. The present invention is characterized in that a file machine for extruding only desired file holders is equipped with a device for restraining the file holders during carrier movement to prevent them from flying out.

The present invention will be described in detail below based on the configuration of the embodiment shown in the drawings. In FIG. 1, a casing 1 is provided with an outlet 2 at a suitable position on its front surface, and 12 carriers 7-1, 7-2, . . . 7-12 is attached to a rotating support 3 such as a chain via an arm 6, and the rotating support 3 is moved up and down by rotating bodies 4 and 5 such as a pair of upper and lower sprockets driven by a motor 8 with a reduction gear. It moves within the casing 1 as it is rotated in the direction. The automatic extraction device 10 is mounted on a longitudinal drive device 9 fixed within the casing 1 so as to be movable in the longitudinal direction.

When the desired file holder number is instructed to an electric control circuit (not shown) of a known technique in which necessary information is stored in advance, the motor 8 is operated under the control of the electric control circuit to store the desired file holder. The carrier (herein referred to as carrier 7-1) is moved to the outlet 2 and stopped. When the carrier 7-1 stops at the outlet 2, the electric control circuit operates the motor 17 in the longitudinal drive device 9, as shown in FIG.
By swinging the crank 21 through the shaft 18, eccentric cam 19, and link 20, the automatic extraction device 10 is advanced and brought into contact with the file holder 11 housed in the carrier 7-1.

On the other hand, the carrier is provided with a pair of restraint mechanisms on both sides of the bottom of the carrier, as shown in FIGS. 2 and 4, and an operating member having a push bar 22 attached to the tip of a rod 23 by screwing or the like. However, the other end is slidably attached to an elongated hole provided in the link 28 with a pin 27, and is also attached to the carrier using a support fitting 24 so as to be slidable in the longitudinal direction. The restraining member 2 to which the link 28 is fixed
As shown in FIG. 3, the numeral 9 extends along the bottom end surface of the carrier on the outlet side, almost over the entire width of the carrier, and is fixed to the bottom end surface with a hinge 30. Also, on the rod 23 of the operating member, there is a split pin 25.
A spring 26, which is an elastic member whose one end is pressed down, is attached between the support fitting 24 and its spring force presses the restraining member 29 in the direction of restraining the file holder.

As shown in FIG. 2, the release member 31 fixed on the automatic extraction device 10 approaches the desired carrier 7-1 stopped at the extraction port 2 as the longitudinal drive device 9, which is a power device, is driven. Push-up bar 2
2 and press it further. Due to this pressing force, the operating member moves against the spring force of the spring 26, and presses the link 28 while sliding along the elongated hole provided in the link 28 via the pin 27. Accordingly, the link 28 and the restraint member 29 rotate about the fulcrum of the hinge 30, and are released from the lower end corner portion of the file holder housed in the carrier, thereby releasing the restraint of the file holder.

After the restraint member 29 rotates to release the file holder restraint and the front-rear drive device stops, the automatic extraction device 10 is activated by a sequential drive mechanism (not shown) consisting of a cam and an electromagnetic device under the control of the electric control circuit. is activated, and first the magnet yoke 15 moves upward, pushing up the iron piece 13 crimped to the end of the selection claw 12 which is slidably provided with respect to the file holder 11. As a result, the selection claw 12 rises by a certain predetermined amount, and the selection claw 12 and the claw locking piece of the automatic extraction device 10, which is generated due to excessive movement of the carrier 7-1 due to inertial movement of the drive motor 8, etc. In order to correct the misalignment with 14, position adjustment is performed.
Subsequently, under the control of the electric control circuit and the sequential drive mechanism, the pawl locking piece 14 at the position corresponding to the desired file holder number is selected and protruded, and the magnet yoke 15 begins to move downward. The iron piece 13 is moved by the magnet attached to the magnet yoke 15.
is attracted, so all file holders 1
1 selection claw 12 tries to descend, but the protruding claw locking pieces 14 are removed except for the desired file holder for which the claws corresponding to the protruding claw locking pieces 14 have been cut in advance.
Since the selection claw 12 is engaged and locked, it cannot be lowered. When the selection claw 12 of a desired file holder is lowered, the ejection plate 16 is projected by the sequential drive mechanism and pushes the selection claw 12.
A desired file folder 11 is extracted.

This completes the extraction process for the desired file holder, but after that the magnet yoke 15 moves upward again to disengage the selection claws 12 and claw locking pieces 14 of the remaining file holders, and the claw locking pieces 14 At the same time as it is retracted, the magnet yoke 15 descends and one extraction process is completed.

The reason why only the selection claws 12 of file holders other than the desired one is locked by the claw locking piece is because the selection claws of all the file holders stored in the carrier are cut in advance in different combinations. The electric control circuit memorizes the cutting combination of the selection pawl corresponding to each file holder number, and when a desired file holder number is specified, the pawl locks at the position corresponding to the cut selection pawl of that file holder. This is for selecting a piece and ejecting it through the sequential drive mechanism. That is, in the example shown in FIG.
The claw locking pieces corresponding to the above are selected and protrude, but since the claws C and D on the file holder side are cut off in advance, they are not locked and the selection claw 12 can descend. However, in case of a file holder other than the desired one, both or one of the claws C and D remains uncut, so that the selection claw 12 is locked by the claw locking piece as shown in FIG. It means that it cannot descend.

When the carrier moves, the motor 17 is operated according to instructions from the electric control circuit, and the automatic extraction device 10 is moved away from the stopped carrier 7-1 by the drive of the longitudinal drive device 9, and the release member 31 and the automatic extraction device 10 are moved away from the stopped carrier 7-1. Since the push bar 22 of the operating member comes out of contact, the restraining member 29 is rotated to the restraining position by the spring force of the spring 26, and as shown in FIG. 7, the file holder is restrained again to prevent it from flying out.

As explained above, the present invention includes a restraint member rotatably attached to the carrier, an operating member that rotates the restraint member, an elastic member that presses the restraint member in the direction of restraining the file holder, and a power source for an automatic extraction device. The present invention is characterized in that a file holder restraining device is provided which has a release member that is driven by the device and rotates the restraining member in a direction to release the file holder restraint via an operating member. With this configuration, the present invention can provide a file holder restraining device that has a simple structure and reliable operation, and can prevent the file holder from flying out when the carrier moves without requiring a complicated mechanism. , which can ensure the selective operation of the automatic extraction device of the file machine.
