Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for sorting the quality of set signatures in an automatic collating machine.

The inventor of the present application has proposed that in an automatic collation device in which a defective collation detector is installed in each of a plurality of feeders (r-alignment machines) in a conventional bookbinding machine, the collation and conveyance operation is carried out in its entirety every time a defective collation is detected. In order to eliminate the inconvenience and decrease in work efficiency of having to stop the machine, have the worker go to the feeder where nine missing pages were added, manually correct the signature supply, and then restart machine operation. , developed a method for eliminating defective signatures.

In other words, in the automatic collation mechanism, pages are missed in each feeder.

A detector is provided for detecting defective collations such as additional sheets, and the system detects defective collations and memorizes the feeder; As the attachment of the conveyor that conveys the included signatures moves by 1 pitch and 2, the above memory circuit is subtracted by 1, and the collective signature containing the defective collation is transferred to the last feeder. This method is characterized in that when the folded sheets reach a predetermined rear position, they are removed from the conveyor system by a discharging device provided at that position.

As a result of further research, the inventor of the present application has found that by using the above method, the quality of the set signatures can be determined in an automatic collating machine that can properly sort and convey the set signatures that are sequentially conveyed according to their quality. This was the successful invention of a transport device.

The present invention will be described in detail with reference to an embodiment in which a conveying device is shown in the drawings to determine whether the sheets are good or bad.

/ is a main conveyor that is installed on the main frame 2 and sequentially conveys the collected signatures 2f intermittently in synchronization with the collating machine. . B is to feed the good set of signatures to one side (right side) when the 2 set of folded signatures sequentially fed from the conveyance end (dash line position, position) of the main conveyor are analyzed. At the time of normal rotation transfer to the side and the same defective set of signatures, the defective set of signatures is transferred to the other side (
A forward/reverse conveyor is provided on the orthogonal frame 3 and is orthogonal to the main conveyor/, which performs the reverse transfer to the discharge side (left side) in response to instructions from the storage command device. That is, a belt is wound around two pulleys each fixed to the driven shaft S and the main drive shaft mounted on the left and right sides of the orthogonal frame 3, and between the pulley 7, and the motor The main drive shaft is rotated via a metering 37 connected between the drive shaft 33 and the drive shaft 33, so that the main drive shaft rotates in forward and reverse directions. Note that tg is a clutch. Further, two pulleys 9 and two side wheels 21I are loosely fitted onto the main driving shaft t. Reference numeral 23 denotes a driven shaft installed near the right end of the orthogonal frame 3, and two pulleys 10 and two chain wheels 25 are fixed to the driven shaft 23, respectively. In addition, // is a large number of receiving rolls, /la is a chain wheel, and 35 is a main drive shaft that is rotated by a drive shaft 3II that rotates in synchronization with the collating machine via a coordinating meter 3g.

27'a to 27d, which shows the structure of the example.
The mounting bracket 110 attached to the chain link of the conveyor 2B has a stopper lI/ and a support part l12, and the support part ψ2 has a dog-shaped bending rod lI3 whose bent part is pivoted about the pivot axis ψt. It is attached with a torsion spring t5 interposed therebetween. The grip part '13tl, which is one end of the bending rod lI3, is engaged with the cam l17 at the trochanter II O of the other end 'l3b, and when the conveyor 2B moves, the grip part '13tl, which is one end part of the bending rod lI3, is engaged with the cam l17. It is constructed so that it can hold two sets of folded sheets in its mouth as shown in Fig. 3.

Next, the operating state of this embodiment of the inventive device will be explained with reference to the drawings.

First, when the set signature 2g that has been intermittently conveyed by the main conveyor l is fed onto the forward and reverse conveyor 6 from the chain line position in Figure 2 as shown, the set signature 2g is a defective set signature. In this case, the motor #-33 rotates in the reverse direction in response to a reverse command from the storage command device, causing the forward/reverse conveyor O to reversely shift to the left.

Then, the defective set of signatures 2g is conveyed to the left, passed through the sheet 32, and discharged to the discharge side. Also, the set signature 2g fed onto the forward/reverse conveyor 6 is a good set signature, 2g
If so, a forward rotation command is given to the motor 33, and the forward/reverse conveyor O is rotated forward to the right, and the good set signature 2 is transferred.
Insert g into the opening of the gripping claw 27tl of the chain puller 2, which is open as shown in Figure 1. Then, at the same time as the forward and reverse conveyor 6 stops, the chain conveyor 26 and the upper and lower belt conveyors 22. /'l starts intermittent transition. And the claw J7. z closes and the chain conveyor 6 carries the good set of signatures 2Ir to the right, but at this time, the good set of signatures, 2g, is transferred to the upper and lower belt conveyor 22 from the middle.
．． /lI- and is transported intermittently while being held between them.

However, the above-mentioned good set signature 2g is transferred to the upper and lower belt conveyor 2.
2. /'l comes out from the conveyance terminal end and reaches a position above the receiving part 29, when the grasping claw 27 (1) of the conveyor 2 opens, it is released and falls into the receiving part 29 below, and temporarily onto the receiving damper 30. will be stopped.

Then, in the next process, for example, when the clamp part of a cover wrapping machine opens and passes, the receiving damper 30 is opened and the good set of signatures 2g that have been stopped in the receiving part 29 are transferred to the next process feeding part 3.

closes. As described above, the set signatures 2 are fed intermittently from the main conveyor 1 onto the forward/reverse conveyor 6 depending on their quality.If the set signatures 2g are good, the next process feeding section 3) on the right side In the case of a defective set of signatures 21r, the sheets are sorted and conveyed to the left discharge side. In addition, as described above, the chain conveyor 26 and the upper and lower belt conveyor/II are equipped with the gripping claws 27tl- and 27d.

2.2 is also associated with a forward/reverse conveyor 6 which is driven in synchronization with the collating machine and moves intermittently in synchronization at a constant speed, and which moves forward/reverse in response to a command from a storage command device, and corrects defective collected signatures 21r. Even when the reversing conveyor 6 is in the process of discharging to the discharge side, the above-mentioned Cheshi conveyor 2B holds the gripping claws 27 (1-
This intermittent transition is performed in synchronization with the collating machine that involves the opening and closing of 27d.

As described above, the apparatus of the present invention automatically and appropriately distributes and conveys the collective signatures that are sequentially fed into the forward and reverse conveyor by the main conveyor intermittently to the next process delivery section or the discharge side depending on the quality. It is possible to do this, and the drive is controlled by the command of the storage command device for detecting defective collation and the operation in synchronization with the operation of the automatic collation device.
It has the advantage of not disrupting the continuity of a series of automatic collation operations or causing any trouble.

In addition, the good set signatures are held in the jaws and conveyed intermittently by the chain conveyor and the lower belt conveyor, and at the same time, from the middle of the conveyance, they are sandwiched between the upper belt conveyor and the lower belt conveyor interposed with each tensile roll. Because it is loaded and transported in a so-called clamped state,
This has an excellent effect of helping to prevent misalignment or curling up of the good set of signatures during conveyance, thereby ensuring stable and proper conveyance of the good set of signatures without any disturbance or deformation.
