Description

Cutting counter for a sheet cutter}

The present invention relates to a counter for cutting machines, and more particularly, by cutting a predetermined size by a knife to count the number of pieces of cutting paper passing through and reaches the set count value to send a marking signal to the inserter between cutting materials The present invention relates to a counter for cutting machine that allows marking paper to be inserted so that cutting and cutting work can be performed simultaneously.

Generally, papermaking, which is needed in the papermaking industry or mint business, is obtained by processing pulp obtained by mechanical, chemical or intermediate processes in wood or other fiber plants.

The pulp is obtained by cutting a solid wood into a certain size with a slansher, peeling the outer skin by putting it in a barker, and grinding it with water in a grinder and then screening impurities. The pulp thus obtained is produced in a papermaking process, a drying process, and a coating process in order, or a specific process is repeated for a specific purpose, and the paper is provided in a form wound on a roller.

The paper wound on the roller is cut into a single piece of paper having a predetermined size by a sheet cutter, and the single piece is counted by the number of sheets packed into the product using a counter, and then marked. Pressurized packaging gives a finished product.

As shown in FIG. 5, the cutting machine 100 includes a conveyor 130 for transferring paper from a plurality of rollers 110 and a cut sheet 111 mounted on an upper portion of the conveyor 130. The knife 131 for cutting the raw paper and the pallet 120 for stacking the cut end 111 attached to the end of the conveyor 130. The cutting machine 100 is cut into a cut sheet 111 of a predetermined size while the paper roll wound on the roller 110 passes through the conveyor 130, the cut cut sheet 111 of the conveyor 130 Stacked on the pallet 120 is located at the end is subjected to a process for counting a certain number through a counter before packing the finished product.

As shown in FIG. 6, the counter is configured such that the counter 210 is mounted on the support 212 fixed to the base plate 211 so that the counter can move up and down. In particular, the counter 210 The head portion 213 for providing the marking paper, the controller 300 for displaying the coefficient setting and the actual coefficient value, and the desired counting amount while rising from the bottom of the pallet to the top in such a manner as to insert the cutting edge by the friction force while actually rotating It is composed of a rotating body 214 to be inserted in accordance with.

As described above, the counter 200 formed as described above, after the cut sheet 111 cut by the cutting machine 100 is stacked on the pappet 120, the pallet 120 is transferred to a safe place, and then cut. Since the edge 111 must be counted, the following problem occurs.

1) The continuity of work is difficult because the process of cutting the rolled paper into a single piece of paper with a certain size and the process of counting the single piece of paper stacked on the pallet are performed separately.

2) Since the number of cutting edges is made by friction as the rotating body rotates, if the two cutting edges are counted as one sheet during the counting, the accurate counting is not achieved. This will require counting to recheck the site.

3) In addition, the coefficient of friction by the friction method often occurs when the cutting material is pinched or torn as the rotating body rotates, which reduces the reliability of the product.

4) The cutting machine rotates at high speed (up to 300m / min), making it difficult to count cutting edges during the cutting process, resulting in the inconvenience of having to count after finishing the cutting process.

The present invention has been made in view of this point, it is mounted on the upper surface of the cutting machine to check the number of cut sheets cut by the knife, and if the cut sheet passes by the set number has elasticity from the shovel by the control signal of the controller The end of the marking paper is stretched out by its elastic force so that the end of the marking paper is inserted between the cutting edges, so that the cutting edge is cut onto the pallet and the counter can be used to check the exact number of pieces by the marking paper. have.

In a preferred embodiment of the present invention, the detector is installed on all or the rear of the inserter on the cutting machine, it characterized in that for detecting the number of cuttings.

In addition, the controller receives the detection signal input from the detector and counts the number of sheets, and when the count amount reaches the ready quantity, the controller outputs a ready signal to the inserter, and when the preset insert quantity equals the count quantity And outputting an insertion signal to the insertion sheet.

In addition, the marking paper is characterized in that the bending ratio of 2: 1 by using a base paper 113g (Base Paper 113g / ㎡) having its own elasticity.

Hereinafter, the configuration and operation of the present invention with reference to the accompanying drawings.

1 is a schematic view showing the configuration of a counter for cutting machine according to the present invention. Here, reference numeral 100 denotes a conventional cutting machine, 110 denotes a roller on which papermaking is wound, and 120 denotes a pallet on which the counted cut sheet is stacked.

In the present invention, the base paper wound on the roll 110 is cut into a single piece of paper 111 having a predetermined size while passing through the cutting machine 100, and the single piece of paper 111 is counted before being stacked on the pallet 120. The marking is to be done every certain number of copies.

According to the present invention for realizing this, the detector 10 outputs a signal thereof as the cut sheet 111 passes, and the operation signal is generated when the counted amount of the cut sheet 111 reaches a set value from the detection signal. It is composed of a controller 20 for outputting, and an inserter 30 for inserting the marking paper 31 into the cut sheet 111 that proceeds at a constant speed in response to the operation signal.

Here, the cutting machine 100 is configured to be continuously conveyed along the longitudinal direction of the conveyor (130 from the left side to the right side in Figure 1) by overlapping a plurality of sheets by a plurality of rollers 110, The conveyor 130 is equipped with a rotary type knife 131 consisting of a slitter for cutting paper in the longitudinal direction and a turning knife (not shown) for cutting the paper in the width direction. It is. The cutting machine 100 formed as described above is cut into paper cuts 111 having a predetermined size by a cutter installed in the longitudinal direction as the knife 131 of the rotary type rotates once.

The detector 10 is mounted on the upper surface of the conveyor 130 to detect the number of cutting edge 111 to be cut and transported as described above, in the preferred embodiment of the present invention is an example of using a photo sensor as a detector Is showing. In addition, the detector 10 may be installed and used between the knife 131 and the inserter 30, as shown in FIG. 1, and may be installed at the rear side of the inserter 30 when viewed in a traveling direction. It is also possible to use. The detector 10 installed as described above detects the count quantity of the cutting edge 111 passing through the upper portion of the conveyor 130 and provides a detection signal to the controller.

The controller 20 receives the detection signal input from the detector 10, counts the number of counts, and controls the inserter 30 when the set value is reached. This will be described with reference to FIG. 2.

In the accompanying drawings, the controller 20 receives inputting values according to the type of inserting and inserting preparation according to the type of product and the 1/2 speed for each type of product (size of the product).

Here, the number of inserts indicates the number of sheets of cut paper when the product is packaged as a finished product, and the amount of preparation is provided to allow time for preparing the marking paper 31 in the inserter 30 by receiving the output signal of the controller 20. It represents the number of sheets used as a preparation signal, and the 1/2 speed for each product size indicates that the sensor recognition position and the insertion position of the insertion device are different when the process that is continuously performed such as failure of the cutting machine 100 or roller replacement is stopped and restarted. Each setting value for compensating the spaced distance is shown.

For example, if the finished product is packaged with 250 sheets of cut paper, the amount of inserts for each product is 250 sheets, and the preparation amount for inserting is less than this, for example, 230 sheets. According to the selection, one or two sheets are respectively shown.

When the setting for each quantity is finished, the cutting machine 100 is operated and the paper is cut with the start of counting, and the inserter 10 is in an initialized state. At the same time, it is determined whether the cutting machine 10 is still in operation or stopped and restarted.

If the cutting machine 100 is stopped and restarted due to replacement or failure of the roller 110 or work stoppage, the cutting machine 100 is further set by the number of sheets set regardless of the number of counts by the value set in 1/2 of the above-described product size. If the cutting machine 100 continues to operate, the count signal is received by receiving the detection signal detected by the detector 10. The count is counted by adding +1 to the count obtained from the first signal input from the detector 10, and the counted count is compared with the prepared count.

In the step of comparing the counting quantity and the preparation quantity, if the counting quantity does not reach the preparation quantity, that is, in the case of the 250-sheet product described above, if the counting quantity is smaller than 230 sheets of preparation quantity, the counting count is repeated again. The controller 20 compares the insertion quantity and the counting quantity with the inserting preparation instruction so that the inserter 30 can prepare the marking paper 31 by the repeated execution of the counting count. Done.

In the process of comparing the insertion quantity and the counting quantity, if the counting quantity is less than the inserting quantity, the counting process is executed again or the process of comparing the preparation quantity and the counting quantity is repeated, and when the counting quantity is equal to the inserting quantity, The insertion instruction of the marking paper 31 is output to the inserter 30, and at the same time, one cycle is completed and the state is returned to the initial state again.

Therefore, the controller 20 is inserted in accordance with the number of inserts per product by the number of counts input from the detector 10 and the preset inserting amount for each product, the inserting preparation amount, 1/2 speed for each product size. The insertion signal can be output to.

Accompanying drawings Figure 3 is a perspective view showing a state in which the insertion machine of the cutting machine counter according to the present invention is mounted.

The shovel 30 uses a RM-151PL (Japan, Chunil Electric Co., Ltd.) counter that is conventionally used for counting.

The inserter 30 may be mounted and used at the rear end of the conveyor 130 as shown in FIG. 1, and may be attached to all of the conveyors 130 according to the mounting position of the detector 10 described above. It is also possible to attach and use.

In particular, the inserter 30 is provided with a marking paper 31 to be inserted between the cutting edge 111 counted by the correct number of sheets, the marking paper 31 is formed in the shape of a strip having its own elastic end portion Part of is provided in a bent form.

The marking paper 31 provides the base paper 113g (Base Paper 113g / m 2) having its own elasticity to the inserter 30 while being wound on a roller in the form of a strip, and the marking paper 31 thus provided is When discharged to the bottom of the shovel 30, it is cut to a predetermined length (e.g., 150 mm and 38 mm in length and width, respectively) and its ends are bent and bent at a ratio of 2: 1 to be unfolded by their elasticity. Consists of.

4A and 4B illustrate an operating state of the shovel according to the present invention. As the shovel 30 is operated by receiving an output signal from the controller 20, the marking paper 31 is cut off ( 111 is inserted into the state.

4A shows a state before the marking paper 31 is inserted, and shows a state where the end is hung by the release crank 32 with the bent end facing downward. This is because the end of the marking paper 31 is forcibly bent and hung by the release crank 32. When the release crank 32 is rotated by the insertion signal of the controller 20, the marking paper ( The end of 31 is rotated downward by its elasticity.

In this state, when the insertion command signal from the controller 20 is input to the inserter 30, the release crank 32 is rotated in the clockwise direction as shown in Fig. 4b, the marking accordingly The end of the paper 31 is rotated to the bottom of the cutting edge 111 by its elasticity. Therefore, the marking paper 31 spread in a cramped shape is sandwiched between the end members 111 continuously moving by the conveyor 130.

The cut end member 111 inserted as described above is counted with the correct number of sheets on the pallet 120 provided at the rear end of the conveyor 130 as shown in FIG.
