Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a conveyor that is used in conjunction with a feeding device that feeds a sheet-like object to a predetermined position, and feeds the sheet-like object into the feeding device.

(Prior Art) This type of feeding device includes, for example, a signature feeding device. During bookbinding, the signatures are stacked in a series of corresponding pockets, and one signature is removed from the bottom of each pocket to collect a book.
For this reason, each pocket must always store an appropriate amount of signatures in an unraveled state, and it is used to supply signatures to such pockets.

The feeding conveyor according to the present invention is preferably used in conjunction with the sheet-like material feeding device disclosed in Japanese Patent Application No. 60-202236 filed by the present applicant.
As shown in FIGS. 5 and 6, the feeding device includes a first feeder 1 consisting of an endless belt, and a pair of endless belts 3, 4 placed above the feeder 1 to sandwich the signatures between them and feed them to the pocket 2. The belt 3 below the second feeder is a perforated belt through which the signatures are sucked and conveyed by the suction cups 6. 7 is a vacuum pump, and 8 is a device for aligning the signatures in the pocket. 10 is a feed conveyor to which the present invention relates.

In this device, the signatures A placed vertically on the feed conveyor 10 are sequentially placed from the most advanced to the most advanced.
Since it is in contact with the belt surface of the first feeder 1 and is pushed by the following one, the friction with the belt surface causes it to rise to some extent, for example, the length of one side of the signature or less, and the feeder 1 and a holding device (not shown)
is pressed against the surface of the belt 3 with appropriate pressure. That part is shown enlarged in FIG. The signatures on the stepped portion are attracted to the surface of the belt 3 by the suction cup 6, rise, and are fed to the pocket 2 while being held between the upper belt 4 and the upper belt 4. With such a step 9, the signatures are pressed against the belt 3 with moderate pressure, so the signatures are picked up and conveyed one by one, which has the advantage of being completely loosened during the transfer process. .

(Problem to be solved by the invention) In such a feeding device, the upper end of the sheet on the feeding conveyor 10 is slightly above the step 9 in order to be pushed by the following sheet. However, in conventional equipment, the infeed conveyor 1
Since the height of 0 was constant, its vertical dimension (fourth
There was a problem in that the device (l ₁ in the figure) could only handle a limited number of sheet-like materials, and items with small vertical dimensions (l ₂ in FIG. 4) could not be fed to a predetermined position.

The object of the present invention is to overcome the above-mentioned problems and, therefore, to provide a sheet feed conveyor that can handle sheets of a wide range of sizes.

(Means for Solving the Problems) The structure that characterizes the conveyor for feeding sheet-like materials according to the present invention includes a conveyor supported on a substrate so as to be movable in the conveying direction, and a device for vertically moving the substrate in parallel. , a guide is included for guiding the conveyor to move obliquely up and down as the substrate moves up and down, and the device for moving the substrate up and down preferably comprises a screw mechanism.

(Operation of the above means) When adjusting the height of the feeding conveyor due to a change in the vertical dimension of the sheet-like object supported on the feeding conveyor, it is sufficient to move the substrate up and down. Because they move up and down together while being restrained by the guide, they also move in the transport direction, and therefore move diagonally. Its angle of inclination is approximately equal to the angle of inclination of the first feeder of the feeding device.

(Example) Next, an example of the present invention will be described with reference to the drawings. This feed conveyor 10 is shown in Figs.
As shown, a substrate 11 supporting a conveyor thereon, a conveyor 12 on that substrate and a substrate 1
It includes a device 13 for performing one vertical movement. Conveyor 12 is preferably a belt conveyor, but other conveyors may be used. The conveyor 12 is supported on the substrate 11 so as to be movable in the direction of its transport, so that in the embodiment shown pins 15 are formed in the substrate 11, supported on the substrate 11 by two pairs of rollers 14 and fixed to the conveyor 12. It engages with a long hole 16 extending in the longitudinal direction (conveying direction). In addition, the conveyor 12
Other structures for longitudinally movable support may be used.

In order to move the board 11 up and down, two pairs of threaded rods 17 are vertically fixed to the bottom surface of the board 11, and each threaded rod 17 is held in place and engaged with a female screw member 18, and each female screw The member has a sprocket 19 fixed thereto. Each sprocket 19 is connected by a chain 20 to a common sprocket 21 which is rotated by a handle 25 through a pair of bevel gears 22, 23 and a main shaft 24. It goes without saying that the main shaft 24 may be rotated by a motor. 2 in Figure 1
6 is a guide roller of the conveyor 12.

Furthermore, this device is equipped with a guide that moves the conveyor 12 diagonally as the substrate 11 moves up and down. In this embodiment, the guide consists of a pair of side plates 27.
It consists of an obliquely extending slot 28 formed in the conveyor 12, and a pin 29 that is fixed to the frame of the conveyor 12 and engages with the slot 28. If it is composed of the slot and the pin in this way, it has the advantage of a simple structure. However, such guides may also use other structures, such as slides. The slope of the slot 28 is approximately the same angle as that of the first feeder 1 of the aforementioned feeding device.

Therefore, in this feed conveyor 10, the handle 2
5 rotates the main shaft 24, the female threaded member 18 rotates and moves each threaded rod 17 up and down through the chain 20 and sprocket 19, thereby moving the substrate 11 and conveyor 12 up and down. At this time, since the pin 29 of the conveyor moves along the groove 28, the conveyor 12 moves up and down as well as in the conveying direction. Move to.

In the above embodiment, a screw mechanism is used to move the board 11 up and down, but it is obvious that this can be easily done by other mechanisms, such as a worm mechanism, a rack-and-pinion mechanism, or a link mechanism. , etc. are also possible. The term "sheet-like material" as used herein means a signature, a unfolded box, or any other paper or thin board that can be handled as a single unit.

(Effects of the Invention) As described above, according to the present invention, the height of the feeding conveyor can be adjusted along the diagonally ascending feeder of the feeding device to which the feeding conveyor is connected. Therefore, sheet-like objects such as signatures can be handled over a wide range of vertical dimensions.
