Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a conveying device that supports thin articles such as signatures in an upright state and gradually conveys them. This type of device is suitably used in a system for feeding signatures into a pocket for a collating machine.

(Prior Art) For example, a system for supplying signatures to a pocket includes a conveying device that supports and gradually feeds the signatures, and a transfer device that sequentially feeds the signatures sent to the tip of the conveying device into the pocket. The signature is configured to be unraveled during the process of being introduced into the transfer device or being moved. It is desirable that the transport device be capable of carrying a large number of signatures, so that the signatures are placed in an upright position. Therefore, the conveying device includes a conveying member that supports thin articles such as signatures in an upright state and gradually feeds them, guide plates provided on both sides, and a holding device that moves with the thin articles to prevent the thin articles from falling over. The holding device, which had been moved to the delivery side of the conveying device, was manually removed from that position and returned to the delivery side, where it was set to hold down the thin material at the rear end. Between pulling out the holding device and setting it, the thin object is no longer held in place and is likely to fall, so the holding device must be returned while making sure that the thin object does not fall.In some cases, the thin object may fall over and It was not easy to handle.

(Summary of the invention) The purpose of the present invention is to solve the problems of the prior art described above, and therefore, it is possible to transport thin objects by temporarily preventing the objects from falling even if the holding device for holding the thin objects is removed. The purpose is to provide equipment.

The thin object conveying device according to the present invention is characterized by a conveying member that gradually conveys the thin object in an upright state, a guide plate arranged on both sides of the conveying member, and a guide plate that engages with the conveying member to hold the thin object so that it does not fall. In a conveying device including a holding device that moves together and is detachably attached to the conveying member, a brush is attached to each guide plate provided on both sides of the device along an appropriate height position thereof. The edges of both sides of the thin object supported there are in contact with the brush, so that even if the holding device is removed, the thin object is prevented from falling due to contact with the brushes on both sides.

(Example) Next, an example of the present invention will be described with reference to the drawings. 1 to 3 show a system including a conveying device according to the invention for feeding signatures into pockets for a collating machine, which system includes a conveying device 1 and a pocket 2 between the conveying device 1 and the pocket 2. A transfer device 3 is provided, and the signatures sent to the tip of the conveyance device 1 are sequentially delivered to the pocket 2 by the transfer device 3.

Since this conveying device 1 supports a large number of signatures,
A conveying member 4 that supports the signatures in an upright state and gradually feeds them, and guide plates 5 disposed on both sides of the conveying member 4.
and a holding device 6 for holding down the signatures so that they do not fall. The conveying member 4 is preferably a pair of endless chains arranged side by side as shown in the figure, but it goes without saying that other members such as a conveyor belt may be used.

The present invention is characterized by the guide plate 5, and as clearly shown in Figs. A brush 7 is attached along the height position and is in contact with the edge of the signature at that position. The brush 7 is the guide plate 5
It is not necessary to provide it along the entire length of the guide plate 5, but it is usually provided over approximately half the length of the inlet side of the guide plate 5, as shown in FIG. Also, brush 7
may be installed continuously, but preferably intermittently at appropriate pitches. It is preferable that the brush 7 is attached to the top of the guide plate 5 at an appropriate height.In this way, the brush 7 can be easily installed and replaced. Further, it is preferable that the interval between the guide plates 5 is adjustable according to the width of the signatures using a handle or the like, as shown by imaginary lines in FIG.

In the illustrated embodiment, the holding device 6 comprises a carriage 10 that engages with and moves along a rail 9 attached to the outer side plate 8 of the guide plate 5, as clearly shown in FIG. horizontal bar 1 attached to
1 and a vertical bar 12 extending downward from the horizontal bar, the lower end of the vertical bar 12 removably engages with the chain 4 and is moved together with the chain. As shown in FIG. 1, in this embodiment there are two holding devices 6.
is provided. Rail 9 Chiyo Pair 13
When the holding device 6 is to be returned, it can be removed from the signature as shown by the phantom line 6' in FIG. Furthermore, the chain 4 is connected to the motor 14.
(Fig. 2). It goes without saying that such a holding device 6 may have other configurations.

The transfer device 3 is composed of a pair of endless belts 15 and 16, as shown in FIGS. is located near the top of the delivery end of the belt 15, and the signatures sent to the leading edge are successively lifted by friction with the belt 15, and when lifted to a certain extent, the belt 1 above it is lifted up by friction with the belt 15.
6, and is configured to be fed into the pocket 2 while being held between a pair of belts. In addition, 17 in FIG. 2 is a control device, 18 is an operating section, 19 is a handle for rotating the threaded rod 20 (FIG. 1), and the conveying device 1 is a nut 21' that engages with the threaded rod 20. The transport device 1 is supported on a support base 22 via a link 21, and the height of the tip of the transport device 1 is adjusted by operating the handle 19.

(Action) Next, the action will be explained. As shown in FIG. 2, on this conveying device 1, the signatures are placed on a chain 4 in an upright state, and since the chain 4 is driven at an extremely low speed by a motor 14, the folds above it are Ding A is gradually moved. The rearmost part of the group of signatures is held down by the holding device 6, and the holding device 6 also moves together with the chain 4, so the signatures are moved while being prevented from tilting backwards by the holding device. , and when it approaches the delivery end of the conveying device 1, it moves forward in an inclined state. Further, in the area near the feeding side, the signature moves while its edges on both sides are in contact with the brush 7 of the guide plate 5. Then, when a certain number of signatures are sent out from the tip of the conveying device 1 and the holding device 6 moves forward as shown in FIG.
As shown in the figure, each holding device 6 is pulled out of the signature by tilting the rail 9 so that the front holding device 6 is in the position of the rear holding device and the rear holding device 6 is near the infeed end of the transport device. In the meantime, send in a new signature. When the holding device 6 is pulled out, the front signatures remain in the same state because they are tilted forward, but the middle and rear signatures sometimes fall backwards with conventional models, but with this device, they do not fold. Since the edges on both sides of the blade are in contact with the brush 7, it remains in this position temporarily, at least until the holding device 6 is reset, and is transported as before.

Note that although the above embodiment deals with signatures, it is also possible to support and convey unfolded paper boxes, flexible thin plates, and other thin objects in the same way.

(Effect of the invention) Therefore, according to the invention, even if the holding device for holding down the thin object is removed, the thin object temporarily remains in an almost upright state. Therefore, it is easy to return and reset the holding device, and this can be done quickly and appropriately.
