Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention is a process of automatically stacking a plurality of signatures folded by a rotary folding machine or the like and stacking a bundle of paper or the like on a pallet, switching a stacking pattern according to the size of a binding laminate and sorting and stacking. And a loading method using the same.

[Prior art]

Conventionally, printing paper printed by a rotary printing press is made into a signature by a folding machine, and the size of a bundle of paper obtained through a stacker and a binding machine that stacks a plurality of the signatures is the size of the take-up paper, that is, the size of the printing paper. There are various patterns depending on the width, how to fold with a folding machine, and how to bind with a stacker and a binding machine. Also, the back side of the signature swells and becomes thicker, and when the bundles are bundled, the paper bundle does not usually have a rectangular parallelepiped shape, and is usually inclined in one or two directions. In order to stack a paper bundle of such a shape on a pallet by a loading machine (industrial robot), the dimensions of the printing paper,
The average size of the paper bundle is assumed for each of the patterns divided according to the folding method and the bundling method, and a machine control program according to each pattern is set to prevent the collapse of the load on the pallet. Under the current circumstances, when the pattern changes, the operator assumes the average size (experientially obtained size) of the paper bundle to be supplied thereafter, and changes the machine control setting every time the pattern changes. (In other words, when a non-contact type detector such as a photoelectric tube is used to measure the size of the paper bundle in the vertical and horizontal directions, the pattern measurement becomes inaccurate due to unevenness or shape instability due to the binding of the paper bundle. Because it was easy to do). By the way, if the size or folding method of the printing paper changes due to a lot change, etc., that is, the pattern changes, if the above setting is neglected, the machine will operate with the previous setting, and the loading machine body and the hand part of the machine Is likely to be damaged. Also, even if you overlook the timing of the setting change and make a change in the middle, it is easy for the loading machine to be damaged due to interference with multiple paper bundles stacked in the previous setting, etc. I could not do it. The above may occur if the operator does not change the setting on the machine every time the pattern is changed, and it is difficult to solve the problem at present.

[Problems to be solved by the invention]

Therefore, when the pattern of the paper bundle changes due to a change in lot, etc., the size of the paper bundle is automatically measured to detect the pattern change, and a change signal such as a machine control program or a paper bundle loading position is sent to the loading machine. The above-mentioned problem can be solved by transmitting to the side. That is, there is an increasing need to automatically measure the size of a sheet bundle to detect a pattern change. However, as described above, due to distortion of the shape of the paper bundle, even in the same pattern (the same printing paper size, folding method, and bundling method), individual paper bundles have variations in vertical and horizontal dimensions. Even if a photoelectric tube or a visual sensor is used, the non-contact measurement by the photoelectric tube or the visual sensor has a problem that an error from a size that is appropriate for an actual bundle of papers is large, and therefore a large error is included. The machine will operate based on the size measured in. Therefore, the present invention has an object to correct the shape, unevenness, and the like of a paper bundle with an appropriate pressing force, and appropriately measure the size of the paper bundle in a distorted state. It is an object of the present invention to operate a loading machine so that a loading table of a predetermined size can be loaded on the loading table of a predetermined size based on the determined size.

A size measuring device 1 including a first measuring unit 2 and a second measuring unit 3 for measuring the size of the bundled stacked product A from the curved path of the transport system a to the end of the transport system a is installed. . In the transport system a, the bundled laminate A moves on the roller conveyor b until it comes into contact with a stopper e facing the end of the roller conveyor b. When the bound laminate A that has stopped in contact with the stopper e is confirmed by the sensor f,
The feed conveyor g disposed at the end of the roller conveyor b rises, and sends out the bundled laminate A to the next roller conveyor c. The bound laminate A moving on the roller conveyor c comes into contact with a stopper h facing the end of the roller conveyor c and stops. Here, the first measuring unit 2 is provided. The first measuring section 2 includes a contact plate 21 provided at the end side of the roller conveyor c so as to be able to move up and down by a cylinder 20, and a pusher 22 provided on the opposite side of the contact plate 21.

The movement amount is read into the control unit 5 connected to the second measurement unit 3. In the control unit 5, the size of the other width of the bundled laminate A is stored from the amount of movement as in the case of the first measuring unit 2. As described above, since the width size in two directions is measured in the first measuring unit 2 and the second measuring unit 3 while applying a predetermined pressing force to the tied laminate A, the tied laminate A itself Is corrected, and the measured values of the vertical and horizontal sizes become appropriate. The size read by the control units 4 and 5 is sent to the sequencer 60 of the control device main body 6 as classified data as shown in FIG. Thus, the loading machine is controlled to perform the operation set for the size of the binding laminate A. That is, based on the vertical and horizontal sizes of the bundled laminate calculated from the pusher movement amount, the loading amount of the bundled laminate and the moving amount of the loading machine to be loaded in the vertical and horizontal directions of the loading table of the predetermined size are calculated.
