Description

  The present invention relates to a blank interval control device for preventing crimping marks in a high-speed automatic iron making machine and a control method therefor.

  The steelmaking blanks folded, glued, and folded by the high-speed automatic ironing machine are sequentially shifted at equal intervals between the crimping conveyors for stable gluing, and all the blanks overlap. Although it is made uniform to reduce crimping marks caused by crimping, there is a large speed difference between the bookmaking machine and the crimping conveyor due to the stacking of blanks made in the crimping conveyor. It is difficult to change this by adjusting both speeds. Therefore, the adjustment of the displacement of the overlapping position in the crimping conveyor is performed by adjusting the interval between the blanks conveyed on the bookbinding machine, that is, by adjusting the speed of the blank fed from the blank automatic paper feeder to the bookbinding machine. ing.

  The conventional automatic paper feeder has the same power source as the bookbinding machine, and the blanking is performed by operating an adjustment dial that continuously adjusts the position of the endless belt that transmits the rotational power of the bookbinding machine to the automatic paper feeder. The interval between the blanks to be supplied is adjusted by finely adjusting the supply speed, but fine adjustment operation of this adjustment dial is very difficult even for a skilled person and requires a long time for adjustment. In addition, even after the supply interval determined to be optimal can be adjusted, the blank may slip or bend at the entrance of the crimping conveyor and the degree of overlap may not be uniform.

  Also, in recent years, in the case of plastic blanks and paper blanks with special surface treatments that have come to be used to increase the commercial value of packaging materials, crimp marks are more conspicuous than conventional blanks. Therefore, there is a problem that adjustment of the overlapping degree with higher accuracy is required.

  Therefore, as one solution, the applicant of the present application provides a section in which the blank clamping pressure is solved on the blank supply line of the high-speed automatic iron making machine in Japanese Patent Application Laid-Open No. 2001-96642, and measures the timing by the detection signal. Correct the distortion and bending of the blank from which the clamping pressure has been released with a two-point stopper, and align the gaps so that the blanks are sent to the ironmaking line at equal intervals. It was proposed to do this by setting the timing.

  However, the invention of this publication has a problem that it cannot be assembled to an automatic iron making apparatus installed in a narrow environment because it requires a long supply line due to the above structure.

  The present invention includes an automatic paper feeder that automatically feeds blanks for ironmaking one by one, a papermaking machine that folds, glues, and folds iron while receiving and transporting the supplied blanks In a high-speed automatic iron making machine that consists of a crimping conveyor that stabilizes the adhesive state of the blanks by overlapping and pressing the blanks in sequence, the blank feeding speed of the automatic paper feeder and the blank transport speed of the iron making machine are managed separately. A blank supply speed changing means is provided to change the deceleration ratio of the blank feeding speed of the automatic paper feeder relative to the blank feeding speed of the bookbinding machine, and it is supplied to the bookbinding machine by adjusting the supply speed. This problem has been solved by adjusting the degree of overlap of the blanks in the crimping conveyor by preventing the occurrence of crimping marks by increasing and decreasing the interval between the blanks to be manufactured.

  Since this invention can adjust the space | interval between the blanks conveyed and ironed only by changing the deceleration ratio of the blank feeding speed of the automatic paper feeder with respect to the blank conveying speed of the bookbinding machine, It is possible to quickly and accurately adjust the optimum overlapping position for various blanks, and to prevent the occurrence of crimping marks on the blank.

  Since the structure is simple and the length of the supply line is not required, there is an effect that it can be assembled to any new to existing automatic iron making machine.

  Since craftsman-based work based on experience is not required, an unskilled worker can easily and accurately perform operations, thereby enabling the production of a stable product.

Description of Example Front view (A) (b) is explanatory drawing which shows the state by which the space | interval on a conveyance belt was adjusted by the supply speed change operation by a controller, and the overlap degree in a crimping conveyor was adjusted.

  The present invention includes an automatic paper feeder that automatically feeds blanks for ironmaking one by one, a papermaking machine that folds, glues, and folds iron while receiving and transporting the supplied blanks In a high-speed automatic iron making machine that consists of a crimping conveyor that stabilizes the adhesive state of the blanks by overlapping and pressing the blanks in sequence, the blank feeding speed of the automatic paper feeder and the blank transport speed of the iron making machine are managed separately. A blank supply speed changing means is provided to control and change the reduction ratio of the blank supply speed of the automatic paper feeder to the blank transport speed of the bookbinding machine, and the blank supply speed is supplied to the bookbinding machine by adjusting the blank supply speed. It is characterized in that the distance between the conveyed blanks is increased and decreased to adjust the overlapping degree of the blanks in the crimping conveyor to prevent the occurrence of crimping marks as much as possible.

  1 and 2 show an embodiment of the present invention. A high-speed automatic iron making machine 1 is made of paper or plastic made blanks B for cutting iron making and laminated one by one from the bottom. An automatic paper feeder 2 that is fed out on 2a and a blank B received from the feeder belt 2a while being transported by the transport belt 3a, folding flaps, glue margins, etc., and performing a steelmaking process such as gluing and folding adhesion The machine 3 and the crimping conveyor 4 that sequentially receives and crimps the plank B that has been produced while shifting the position at regular intervals.

The paper feeder 2 and the bookbinding machine 3 are operated separately by motors М1 and М2 with a variable rotation mechanism such as an AC servo motor. Reference numeral 5 denotes a controller that can be connected to the motors М1 and М2 to control and manage the motors М1 and М2. The rotation speeds of the motors М1 and М2 are set to the blank B supply speed of the automatic paper feeder 2 and the blank B of the bookbinding machine 3, respectively. A speed reduction ratio display section 5c of the supply speed with respect to the transport speed is provided together with a feed speed display section 5a and a transport speed display section 5b that are converted into the transport speed, and the speed reduction ratio is changed to the side of the speed reduction ratio display section 5c. An up / down operation button 5d is provided.

  When the conveyance speed of the blank B of the bookbinding machine 3 is set according to the type of blank B and the number of processes, the speed is displayed on the conveyance speed display section 5 b of the controller 5. Then, as shown in FIGS. 2 (a) and 2 (b), the supply speed of the blank B is set to 70% by operating the up / down operation button 5d, for example, with respect to the conveyance speed 50m of the bookbinding machine 3, and the supply speed. Is 35 m, and when the deceleration ratio is set to 82%, the supply speed is immediately changed to 41 m.

  The size of the overlap shift width of the blanks B that are sequentially stacked and pressure-bonded in the crimping conveyor 4 is determined by the distance between the blanks B and B that are transported and steeled. The supply speed of-is slowed, the interval between the blanks B to be conveyed and manufactured becomes wide, and the shift width of the overlapping position in the crimping conveyor 4 becomes large. On the contrary, when the reduction ratio is increased, the supply speed of the blank B is increased and the interval between the conveyed blanks B is narrowed, so that the shift width of the overlapping position on the crimping conveyor 4 can be reduced. Since the overlap angle changes depending on the size of the overlap position shift width in the crimping conveyor 4, the pressure contact force is optimally distributed according to the shape, material type, and size of the blank B to be manufactured. Occurrence can be prevented.

  When the paper grain is in the horizontal direction with respect to the conveyance direction in addition to the material that is slippery when it is stacked on the crimping conveyor 4, the presence or absence of special surface treatment, the thickness of the material, the difference in the number of folded folds, etc. The occurrence of crimp marks can be prevented or greatly reduced depending on various blanks B, such as adjusting the deviation small and increasing the deviation width in the case of the vertical direction. Since the adjustment is performed by inputting a numerical value of the reduction ratio by the operation button, anyone can adjust the speed quickly and accurately without requiring the experience of operating the adjustment dial of the conventional transmission belt.

  The present invention makes it easy for anyone to make adjustments to prevent the occurrence of crimp marks in an automatic iron making machine, and can also be installed in an existing automatic iron making machine installed in a narrow place. It is widely used as something that can be used.
