Description

  The present invention relates to a method for processing a product and a punched residue in a Thomson blade punching machine that punches a plate material that can be used to assemble a paper container such as a cardboard box from a material such as a plate-like paper such as cardboard.

  FIG. 8 is a front view of a conventional manual Thomson blade punching machine. In the figure, 101 is a press lower surface plate, 102 is a press surface plate, 103 is a Thomson blade, 104 is a press surface plate, and the press surface plate 104 moves onto the press lower surface plate 101 and is pressed by the Thomson blade 103. Then, the sheet is punched, and thereafter, the sheet 105 is moved to the discharge table 108 by the gripper 106, and the sheets 105 are stacked to form a sheet 107 after being extracted. This is suitable when working on small lots and is often used because the cost of the machine is cheap and the work is easy. The work of removing the sheet requires only the removed product, which is delivered and does not require removal. When complete extraction is performed in this extraction press process, the extracted residue and the product are scattered when moving with the gripper, and cannot be moved to the discharge table. Accordingly, as shown in FIG. 10, a plurality of tabs 113 are provided so as to connect the product 111 and the extracted residue 112. Accordingly, the punched product 111 and the punched residue 112 are stacked on the punched sheet 107 without being separated. In the subsequent process, both are separated manually, but this is a difficult task. Actually, since it takes too much labor to work on each sheet, 10 to 20 sheets are separated together. There is no more method than cutting the jumpsuit 113 with a cutter or hitting it with a hammer or the like. Ideally, the punched product 111 and the punched residue 112 are separated and only the punched product 111 is stacked on the discharge table 108, but there is no such machine at present.

  FIG. 9 is a front view of a Thomson blade punching machine automatic machine. The parts common to FIG. 8 are given the same reference numerals, and the added parts are given new reference numerals, 109 being a feeder and 110 being a chain gripper. Sheets 105 are fed one by one from the feeder 109, stopped by the chain gripper 110 at the position of the lower press platen 101, punched by the Thomson blade 103, moved to the discharge table 108 by the chain gripper 110, and the sheets 105 are stacked and pulled out. It becomes the rear sheet 107. It is the most used machine because it is suitable for large lot work.

  In this machine, as in the case described above, if the paper is completely pulled out in the punching press process, when the chain gripper 110 moves to the discharge table 108, the scrap and product are scattered, and the machine cannot move to the discharge table. Accordingly, as shown in FIG. 10, a plurality of tabs 113 are provided so as to connect the product 111 and the extracted residue 112. Therefore, the punched product 111 and the punched residue 112 are stacked on the post-cut sheet 107 without being separated. In the subsequent process, both are separated manually, but this is a difficult task. Actually, since it takes too much labor to work on each sheet, 10 to 20 sheets are separated together. There is no more method than cutting the jumpsuit 113 with a cutter or hitting it with a hammer or the like. Ideally, the punched product 111 and the punched residue 112 are separated and only the punched product 111 is stacked on the discharge table 108, but there is no such machine at present.

  FIG. 11 is a front view of a Thomson blade punching machine with a product dropping device. Sheets 105 are fed one by one from the feeder 109 and stopped at the position of the press lower platen 101 by the chain gripper 110, punched out by the Thomson blade 103, moved to the position of the product dropping knife mold 116 by the chain gripper 110, and stopped. A product drop male press 115 is used to separate the punched product from the product and drop only the product at the position of the stacked punched product 111. Further, only the punched residue is loaded onto the discharge table 108 by the chain gripper 110. It is a machine that goes by. This is also a machine that is often used because it is suitable for large lot work.

  Similarly to the above two, if the machine is completely pulled out in the punching press process, when the chain gripper 110 moves to the product dropping knife mold 116, the scrap and product will be scattered and cannot be moved. Accordingly, as shown in FIG. 10, the tabties 113 are provided at a plurality of locations so as to connect the extracted product 111 and the extracted residue 112.

  A product drop mold comprising a product drop male mold 115 and a product drop female mold 116 is manufactured by applying laser beam processing to a plywood board. This is not all the same, and each product must be set to match the machine with the male and female.

  By pressing using the product drop mold, the jump 113 can be cut and the product and the punched residue can be separated.

  However, this machine is expensive and making a product drop mold is expensive. In addition, it takes a lot of time to set the product drop type male and female types on the machine. Therefore, a large lot of work doesn't matter the large cost of making a product drop mold and the great time to set the product drop male and female molds on the machine. The cost of making the mold and the time required to set the drop-type male and female molds on the machine are problems, and in reality they cannot be used.

  According to the present invention, the work in the Thomson blade punching machine in such a situation does not have to be a laborious work in which the product and the cutting residue are separated by the hand of a conventional person, and the knife for dropping the product is used.・ No need for male molds, so there is no need to set these molds on the machine, and even if products with different product shapes and sizes are laid out in a single sheet, separation of the products and waste is easy. Therefore, it is an object of the present invention to make it possible to obtain a product in a state in which a product and a waste residue are separated as desired regardless of the size of a production lot.

  According to the present invention, the above-described problem is that the sheet to be processed is punched with a Thomson blade to make the product and punched residue, and the sheet is moved to the next process while maintaining the mutual position of the product and punched residue. A step of transferring, and a step of changing the transfer direction of the extracted dregs in a direction different from the transfer direction of the product by hooking the edge of the extracted dregs of the conveyed sheet by the separation claw and the guide means connected thereto. This is solved by using a method for treating a product and a punching waste in a Thomson blade punching machine, which separates the punching waste and sends it to the next process in a different direction.

  Further, according to the present invention, the above-described problem is that the sheet to be processed is punched with a Thomson blade in order to make the product and punched residue, and the sheet is processed next while maintaining the mutual position between the product and punched residue. And a step of changing the transfer direction of the punched debris to a direction different from the transfer direction of the product by hooking the edge of the punched debris of the sheet to be transferred by the separation claw and the guide means connected thereto. The process of separating the product and the dregs and sending them to the next process in different directions, and controlling the action of the separation claw by moving the position of the separation claw up and down by a sensor that detects the position of the product in the conveyed sheet The Thomson blade punching machine uses the processing method for the product and the punching waste to separate the product and the punching waste and send them to the next process. Kill.

  In addition, according to the present invention, the above-described problem is that a plurality of products that are separated from the punch and are transferred while maintaining the mutual positional relationship when punched are placed on the lower air adsorption belt conveyor and sucked downward. And transferring the product to the lower air adsorbing belt conveyor from the previous transfer means to the lower air adsorbing belt conveyor surface from above with a sphere or a roller. This can be solved by using the processing method of the product and punching waste in the Thomson blade punching machine.

  In addition, according to the present invention, the above-described problem is that a sheet to be processed is punched with a Thomson blade to make a product and a scrap, and after the process, air is blown from the lower surface side to force both. This can be solved by using a method for treating a product and a punched dregs in a Thomson blade punching machine characterized by including a step of separating.

  Further, according to the present invention, the above-described problem is that the lower air adsorption belt conveyor sucks downward while maintaining the mutual positional relationship when a plurality of products to be separated and transferred are placed and punched. A step of transferring, a step of interrupting air suction of the lower air adsorption belt conveyor when the plurality of products reach a predetermined position, and an upper air adsorption provided with a gap above the lower air adsorption belt conveyor. A step of lowering the belt conveyor, a step of performing air suction of the upper air adsorption belt conveyor to adsorb and hold the product on the lower surface of the upper air adsorption belt conveyor, and a transfer of the product to a predetermined position by the upper air adsorption belt conveyor.

A product and a punching waste in a Thomson blade punching machine, wherein the suctioning is interrupted and the product is dropped to a predetermined position and stacked, and the product is transported and stacked while maintaining the mutual positional relationship when punching It is solved by the processing method.

  According to the present invention, the work in the Thomson blade punching machine does not have to be a laborious work in which the product and the punched residue are separated by the hand of a conventional person, and the female / male type for dropping the product. Therefore, there is no need to set these molds on the machine, and even if products with different shapes and sizes of products are laid out in one sheet, the product and the waste can be easily separated. Regardless of the size of the production lot, it is possible to obtain an advantageous effect that can be obtained in a state where the product and the dregs are separated as desired.

  The process of punching with a Thomson blade to make the sheet into the product and the waste, the process of transferring the sheet to the next process while maintaining the mutual position of the product and the waste, and blowing both air from the lower surface side A step of forcibly separating, a step of hooking the edge of the sheet to be removed by the separation claw and the guide means connected thereto, and changing the direction of the removal of the discharged residue in a direction different from the direction of transferring the product; The process of moving the position of the separation claw up and down by the sensor for detecting the position of the product in the sheet to control the action of the separation claw and transferring the product and the dregs in different directions, and the upper air suction conveyor belt And a lower air suction conveyor belt, and the product is transferred to a predetermined position by a cooperative action and laminated by product.

  FIG. 1 is a front view of an embodiment of the present invention. 1 is a press lower platen, 2 is a press receiving platen, and 3 is a Thomson blade. A sheet 5 is manually placed on the press surface platen 4, and the press surface platen 4 moves onto the press lower surface plate 1 and is pressed by the Thomson blade 3 to punch out the sheet, and a press lower surface plate having a vertical mechanism. The sheet is fed to the feeding rubber roller 17 by the sheet feeding rubber roller 32 at the position where 1 is completely lowered, and only the scrap is hooked by the separation pawl 22 and the lower scrap 26 is discharged downward through the pulling guide 25. And stacked. On the other hand, since the punching waste 26 falls to the lower surface, the product 28 is lifted from the punching waste and separated and sent to the next feed rubber roller 18.

  Details of the periphery of the separation claw 22 are shown in FIG. Reference numeral 17 denotes a front feed rubber roll, 18 denotes a rear feed rubber roll, 19 denotes a product holding ball, 20 denotes a lower air adsorption conveyor belt, 21 denotes an air blowing nozzle, 22 denotes a separation claw, 23 denotes a detection sensor, 24 denotes a pneumatic cylinder, 25 Is a guide for removing waste, 26 is a waste residue, 27 is an upper air adsorption conveyor belt, 28 is a product, 29 is an air cylinder, 30 is a roller lever, and 31 is a limit pin.

  In FIG. 3, when the sheet 5 that has been punched in the direction of arrow F is fed into the feed rubber roller 17, the bowl-shaped separation claw 22 is in the position A protruding upward from the feed surface in this state. I'm hooked on this. At this time, according to the arrangement setting of the separation claws described below, only the extracted residue 26 is discharged through the extracted residue guide 25 and stacked.

  FIG. 2 shows an arrangement state of the product and the punched debris in which the sheet 5 is punched by pressing with the Thomson blade 3. In FIG. 2A, two identical products 28 are arranged in parallel in the sheet 5 in two rows, and in this example, the separation claw 22 has both ends of the width in the feeding direction of the sheet 5 in the direction of arrow E. The separation claw 22 can change the direction of the extraction dregs from the start end to the end of the extraction dregs and obtain an effective separation process. In FIG. 2B, six identical products 28 are arranged in parallel in three rows and two rows in the sheet 5, and in this example, the separation claw 22 is in the direction of the arrow 5 in the feeding direction of the sheet 5. The separation claw 22 can change the direction of the extraction dregs from the start end to the end of the extraction dregs by providing them at the two ends of the width and at two places in three equal positions of the width, so that an effective separation process can be obtained. In FIG. 2C, sixteen identical products 28 are arranged in parallel in four columns and four rows in the sheet 5, and in this example, the separation pawls 22 are in the direction of the arrow 5 in the feeding direction of the sheet 5. The separation claw 22 can change the direction of the extraction dregs from the start end to the end of the extraction dregs by providing them at both ends of the width and 3 parts of the quarter of the width, that is, an effective separation process. As described above, the separation claw 22 is configured so that the position on the line orthogonal to the sheet transfer direction and the number of the separation claws 22 can be arbitrarily set and changed.

  Next, as shown in FIG. 2 (d), when products having different shape dimensions are arranged in the sheet 5, since the pattern of the punched residue cannot be obtained in a straight line in the direction of the arrow E, separation is performed. Of the claws 22, in this example, the separation claws 22a and 22b are respectively caught on the product 28a and the product 28b, and the product is pulled out and guided in the waste guide direction. Therefore, in the case of such a layout, the separation claws 22a and 22b are displaced and moved.

  Details of this part are shown in FIG. Although referring to FIG. 2 again, 17 is a front feed rubber roll, 18 is a rear feed rubber roll, 19 is a product holding ball, 20 is a lower air adsorption conveyor belt, 21 is an air blowing nozzle, 22 is a separation claw, 23 is a detection sensor, 24 is a pneumatic cylinder, 25 is a discharge guide, 26 is a discharge waste, 27 is an upper air adsorption conveyor belt, 28 is a product, 29 is an air cylinder, 30 is a lever with a roller, 31 is a limit pin is there.

  When the sheet 5 is fed and the sensor 23 detects and operates the boundary between the product 28a and the punch 26, the separation claw 22 is moved by the pneumatic cylinder 24, the lever 30 with the roller is moved by the limit pin 31 and the separation claw 22 has been fed until now. It is lowered from the position of A projecting further upward to the position of B not projecting and escapes from the feed surface. Therefore, only the punched residue 26 is guided downward by the separation claws 22 at the left and right ends in FIG. 2D, and the product 28 is lifted from the punched residue and separated and sent to the next feed rubber roller 18. Even with a sheet as in (d), the product and the waste can be separated.

  1 to 3, when the sheet is punched by pressing with the Thomson blade 3, depending on the shape of the Thomson blade, the product 28 may not be easily lifted from the residue 26 and may not be separated, and therefore the sheet 5 is sent. When the sensor 23 detects this, air is blown from the air blowing nozzle 21 to the lower surface of the sheet 5 to forcibly separate them.

  The product 28 is separated from the scrap and is fed in the direction of arrow G by the rear feed rubber roll 18 in FIG. 3 and reaches the lower air adsorption conveyor belt 20 described later. Since there are a plurality of products 28 and they are not necessarily of the same shape, it is necessary to send them while maintaining the positional relationship that has been sent when they are dropped downward in the subsequent process and stacked according to product type. The lower air adsorbing conveyor belt 20 has a certain area, and sucks air into the inside so as to be able to move while maintaining the mutual layout of the products so as to meet this purpose. Further, a product holding ball 19 having a rotatable structure is disposed above the starting end of the lower air adsorption conveyor belt 20, and the product 28 is transferred while being kept in a predetermined position by the lower air adsorption conveyor belt 20. At the same time, the product holding ball 19 presses the product from above with its own weight, thereby further maintaining the predetermined position. A plurality of the product holding balls 19 are arranged at right angles to the traveling direction, but can be replaced with a roller-shaped member.

  In FIG. 1, 20 is a lower air adsorbing conveyor belt, and 27 is an upper air adsorbing conveyor belt, both of which cooperate to ensure product transfer and stacking. Details of the structure are shown in FIGS. 4 is a front view of the lower air adsorption conveyor belt 20, FIG. 5 is a top view thereof, 201 is a vacuum air box, 202 is a duct, 203 is an air suction hole, 204 is a hose, and 205 is a ring blower. Also, 206 is a belt, 207 is a large number of air suction holes arranged around the entire belt surface, 208 is a belt tension roller, 209 is a tape roller, and 210 is a duct.

  6 is a front view of the upper air adsorbing conveyor belt, FIG. 7 is a top view thereof, 270 is an air switching valve, 271 is a vacuum air box, 272 is a duct, 273 is an air suction hole, 274 is a hose, 275 is a ring It is a blower. Further, 276 is a belt, 277 is a predetermined portion of the belt surface, a plurality of air suction holes arranged in a predetermined range, 278 is a tape tension roller, 279 is a tape roller, 280 is a duct, and 281 is a servo motor.

In FIG. 1, when the product 28 separated from the punched waste 26 is fed leftward by the rear feed rubber roll 18, the product 28 is put on the lower air adsorption conveyor belt 20.
The lower air adsorption conveyor belt 20 includes a vacuum air box 201, a duct 202, an air suction hole 203, a hose 204, a ring blower 205, a belt 206, an air suction hole 207, a belt tension roller 208, a tape roller 209, a duct 210, and the like. By the action, the product 28 riding on the air suction holes 207 arranged in a large number around the entire belt surface is sucked and moved to the left in the drawing while maintaining the position.

  The product 28 is transferred to the left in the drawing by the lower air adsorption conveyor belt 20 and is temporarily stopped when it reaches a predetermined position. The position is shifted slightly to the left as shown in FIG. 1 above the lower air adsorption conveyor belt 20. The arranged upper air adsorbing conveyor belt 27 descends to a predetermined position by the operation of the pneumatic cylinder 29, adsorbs the stopped product 28 on the lower air adsorbing conveyor belt 20, and then pneumatically The cylinder (air cylinder) 29 is moved up by the operation of the cylinder 29 and moved to a position just above the position of the discharge table 8 by the operation of the servo motor 281 to stop the suction air. The product 28 is dropped and the discharge table 8 is dropped. It is a structure that piles up as a product group.

  By the cooperative action of these two air adsorbing conveyor belts, each product that has been separated from the unloading residue can be transported in the state where it has been pulled out while maintaining the relative position. Since they can be stacked separately, the subsequent sorting and sorting process is not necessary.

The above-described processing method of the present invention is a Thomson blade punching machine equipped with a sheet transfer means for bringing a sheet sent from a sheet feeder onto a lower surface plate using the chain gripper described above with reference to FIG. The present invention can also be applied to a method for processing products and punched waste.
