Abstract

PURPOSE:To load a paper bundle properly on a loading table of prescribed sizes on the basis of sizes obtained by measurement, by measuring properly the sizes of the paper bundle in a distorted state by modifying the shape, unevenness and others of the paper bundle by an appropriate pressing force. CONSTITUTION:In a conveyance system of a bound stack A, a back plate 21 (31) and a pusher 22 (32) in a measuring element 2 (3) confront each other and the pusher 22 pushes the bound stack A against the back plate 21 so that a paper bundle is held therebetween. The movement of the pusher 22 with the application of a pressing force to the bound stack A is detected by a detecting means 26 constructed of an encoder, for instance. The amount of movement (the amount of movement from a reference position) of the pusher 22 made until the pressing force by the pusher 22 becomes a prescribed pressing force is detected and the width of the bound stack at that time point is calculated as a measured value. According to the measured value, the size of the stack in the course of conveyance is set, and by the operation of a loading machine on the basis of this size, the stack A arriving at a prescribed place of the conveyance system is assorted and sent to a plurality of loading stages such as pallets.

Description

[Detailed description of the invention] [Industrial application field]

The present invention is a process of automatically stacking paper bundles made by stacking a plurality of signatures folded by a rotary folding machine into a barret, and the stacking pattern is switched according to the size of the bound stack. Sorting relates to a size measuring device for loading and a loading method using the same.

[Conventional technology]

Conventionally, printed paper printed by a rotary printing machine is turned into signatures by a folding machine, and the size of the paper bundle that is put together through a stacker and binding machine that stacks multiple signatures is the size of the paper roll, that is, the size of the printed paper. There are various patterns that vary greatly depending on the width, how to fold with a folding machine, and how to bundle with a stacker and binding machine. In addition, the backs of the signatures swelled and became thicker, and when they were bundled together, the bundle of papers did not form a rectangular parallelepiped, but usually tilted in one or two directions. In order to load a stack of paper with this shape onto a pallet using a loading machine (industrial robot), each pattern is divided by the size of the printed paper, how it is folded, and how it is bundled.
In addition to assuming the average size of the paper stack, machine control programs are set according to each pattern to prevent the stack from collapsing on the balent. Currently, when the pattern changes, the worker assumes the average size (size obtained from experience) of the stack of paper that will be supplied from then on, and changes machine control settings each time the pattern changes. (In other words, this means that if a non-contact detector such as a phototube is used to measure the vertical and horizontal size of a paper stack, the pattern measurement will be inaccurate due to irregularities or unstable shapes caused by bundling the paper stack.) (This was because it was easy). By the way, if the size or folding method of the printing paper changes due to a lot change, in other words, if the pattern changes, if the above settings are ignored, the machine will operate with the previous settings, and the loading machine itself and the hand part of the machine will This makes it more likely that damage to the product will occur. Furthermore, even if you miss the timing to change the settings and change them midway through, damage to the loading machine is likely to occur due to interference with multiple stacks of paper stacked with the previous settings (in reality, the settings are changed midway through). Changes could not be made.The above-mentioned problem may occur unless the operator changes the settings on the machine each time a pattern is changed, and it is difficult to solve the problem at present.

[Invention or problem to be solved] Therefore, when the pattern of a stack of paper changes due to a lot change, etc., the size of the stack of paper is automatically measured to detect the pattern change, and changes signals such as the machine control program and the stack loading position are sent to the loading machine. If the data is sent to the side, the above problem can be solved. That is, there is an increasing need to automatically measure the size of a paper stack and detect pattern changes. However, as mentioned above, due to distortions in the shape of the paper stack, even within the same pattern (printed paper size, folding method, and bundling method are the same), the vertical and horizontal dimensions of individual paper stacks vary, making automatic paper stack size detection difficult. Even if a phototube or visual sensor is used, non-contact measurement using a phototube or visual sensor has the problem of a large error between the size and the size that is considered appropriate for the actual stack of paper. The machine will operate based on the measured size. Therefore, the object of the present invention is to correct the shape, unevenness, etc. of the paper stack by applying appropriate pressing force, and to properly measure the size of the paper stack in a distorted state. The purpose of the present invention is to operate a loading machine so as to be able to load just the right amount on a loading platform of a predetermined size based on the specified size. [Means to solve the problem]

The present invention has been made in consideration of the above-mentioned problems, and is installed in a conveyance system for conveying a bundled laminate made by bundling a plurality of signatures of the same size. a first measuring section that sandwiches the laminate between a backing plate and a pusher; and a second measuring section that sandwiches the bound laminate between a backing plate and a pusher in the other width direction of the bound laminate, the first measuring section Provided is a size measuring device for a bundled laminate, characterized in that a detecting means is provided in each of the pushers and the ears of the second measuring section to detect the amount of pusher movement until the pushing force by the pusher reaches a predetermined pushing force. This solves the above problem. Another invention is a device installed in a conveyance system for conveying a bundled stack consisting of a plurality of signatures of the same size, and located in the conveyance system and rotates in a direction perpendicular to the direction of conveyance. and a measuring section for sandwiching the bundled laminate on the conveying rotating table between a backing plate and a pusher, and a pusher for pushing the pusher of the measuring section until the pressing force by the pusher reaches a predetermined pressing force. The object of the present invention is to provide a size measuring device for bundled laminates, which is characterized by being provided with a detection means for detecting the amount of movement, thereby solving the above problems.Furthermore, another invention provides a size measuring device for bound laminates. Based on the vertical and horizontal sizes of the bundled laminates calculated from the amount of pusher movement of the detection means in The above problem is solved by calculating the amount, controlling the loading machine based on the calculated amount, and loading the bound laminate onto the corresponding loading platform.

[Function] In the present invention, in the bundled laminate transport system, the backing plate and the pusher in the measuring section face each other, and the pusher presses the bundled laminate against the backing plate so as to sandwich the paper bundle. The movement of the pusher due to the application of a pressing force to the bundled laminate is detected by detection means such as an encoder. Then, the amount of movement of the pso/yar (movement amount from the reference position) until the pressing force by the pso7ya reaches a predetermined pressing force is detected, and at that point, the width of the bundled laminate is calculated as a measured value. Then, the size of the stack being transported is set from the measurement value, and the stacking machine operates based on this size, so that the stack that has reached a predetermined location in the transport system is sorted onto a plurality of loading platforms such as pallets. Embodiments Next, the present invention will be explained in detail based on embodiments shown in FIGS. 1 to 5. Conveyance system a consisting of a combination of roller conveyors is a first

The first measuring section 2 is installed here. The first measuring section 2 consists of a patch plate 21 provided on the side of the terminal end of the roller conveyor C so as to be movable up and down by a cylinder 20, and a puller 22 provided on the opposite side of the patch plate 21. The pusher 22 has a cylinder 23 that pushes it out in the width direction above the roller conveyor C, and also has a detection means 26 consisting of a measuring rod 24 and a low lifter 25 that detects the amount of movement of the measuring rod 24. have,
The measuring rod 24 is provided so that the amount of movement of the punonoya 22 is detected by reading the amount of movement of the measuring rod 24. Bundled laminate A is safe at the end of roller conveyor C -1
+ i i: Therefore, when confirmed, cylinder 20t7)
The backing plate 21 rises and stops due to the U operation. Then, by the operation of the cylinder 23, the needle 22 is pushed out from the specified position, and the bundled laminate A is pressed against the backing plate 21 and sandwiched therebetween. Then, the amount of movement from the specified position up to the time when a predetermined pressing force is applied by the puno/yaar 22 is detected by the detection means 26, and the amount of movement is read into the control section 4 connected to the first measurement section 2. In this control section 4, the size of one width of the bundled laminate A is stored from the amount of movement. After this, Pusonya-22 was evacuated and the backing plate 21
descends, and in its place the feed conveyor j, which was located at the end of the roller conveyor C, rises and sends out the bundled laminate A to the roller conveyor d side. The bundled laminate A moving on the roller conveyor d comes into contact with a stopper k positioned facing the end and stops. The second measuring section 3 is installed at this stop position. This second measuring section 3 includes a backing plate 31 which is provided on the roller conveyor d so as to be movable forward and backward by a predetermined distance in the width direction of the roller conveyor d by a cylinder 30 on the side of the terminal end of the roller conveyor d; It consists of a Phnomiya 32 installed on the opposite side of the The pusher 32 has a 7 cylinder 33 that pushes it out in the width direction above the roller conveyor d, and a detection means consisting of a measuring rod 34 and a rotary encoder 35 that detects the amount of movement of the measuring rod 34. 36, and is provided so that the amount of movement of the pusher 32 is detected by reading the amount of movement of the measuring rod 34. When the bundled pile A is confirmed by the sensor l at the end of the roller conveyor d, the cover plate 31 moves forward by a predetermined amount by the operation of the cylinder 30 and then stops. and cylinder 33
By this action, the psonoya 32 is pushed out from the specified position, and the bundled laminate A is pressed against the backing plate 31 and sandwiched therebetween. Then, the amount of movement from the specified position up to the time when the pusher 32 applies a predetermined pressing force is detected by the detection means 36, and the amount of movement is read into the control section 5 connected to the second measurement section 3. In this control section 5, the first
As in the case of the measurement unit 2, the size of the other width of the bundled laminate A is stored from the amount of movement. As described above, since the width size in two directions is measured while applying a predetermined pressing force to the bundled laminate A in the first measuring section 2 and the second measuring section 3,
Its own distortion is corrected, and the measured values of the vertical and horizontal sizes become appropriate. The sizes read into the control units 4 and 5 are sent as classified data to the sequencer 60 of the control device main body 6, as shown in FIG.
The loading machine controller 61 receives the signal from 0 and controls the loading machine to perform an operation set for the size of the bundled laminate A. In other words, based on the vertical and horizontal sizes of the bundled laminates calculated from the amount of pusher movement, the loading amount of the bundled laminates to be loaded in the longitudinal and lateral directions on a loading platform of a predetermined size without excess or deficiency and the amount of movement of the loading machine are calculated. Ru. Then, based on the calculated amount, the loading machine is loaded so as to load the bundled laminate onto an appropriate loading platform. The loading machine controller 61 is programmed so that the loading operation on the loading table on which the bundled laminate is loaded corresponds to each of the plurality of assumed vertical and horizontal width sizes of the bundled laminate. In other words, the loading machine controller is programmed in advance to store stacks of combinations of vertical and horizontal sizes of multiple types of ■, ■, ■, ■, ■, ... in the table above, and the placement position of the loading platform (loading device operation).
The placement position of the stack on the loading table is determined by the signal from the sequencer and information on the loaded stack. The vertical movement of the loading machine is controlled by detection means such as a limit switch. In the above-described first embodiment, the feed conveyor j located on the roller conveyor b is designed to prevent the next bundled laminate from moving toward the first measuring section 2 during measurement of the bundled laminate due to the feed conveyor j being raised. It also serves as a stopper. The installation positions of the first measuring section 2 and the second measuring section 3 in the first embodiment can also be set at each curved route portion of the transport system a, as shown in FIG. In this case,
A stopper m that moves up and down on the roll conveyor b on the upstream side of the first measurement section 2 and a sensor n that detects the presence or absence of a bundled laminate in front of this stopper m are attached, and the next bundled laminate is placed in the first measurement section during measurement. are designed to prevent intrusion.
