Title: Die cushioning device for press machine
Inventor: ARIKAWA TAKAMASA
IPC: B30B15/02
Filed: 1987-08-28
Abstract: PURPOSE:To reduce the generation of noise at press working time by freely adjusting the pressing force of a hydraulic cylinder with the adjustment of a servovalve and adjusting the servovalve so that the relative moving speed of a blank holder to an upper die slows down. CONSTITUTION:A control device 36 transmits a control signal 37 to a servovalve 19 based on a detection signal 32 showing the position of an upper die 29 transmitted from a position detector rotary encoder 31. The pressing force of hydraulic cylinders 2, 3 is controlled by executing the press oil feeding and discharging of upper and lower oil chambers 10, 11, 12, 13 of hydraulic cylinders 2, 3 by the servovalve 19. In case of the descent of the upper die 29, the servovalve 19 is actuated to descend a blank holder 9. The generation of noise caused by clamping the material 39 with the upper die 29 is thus prevented. Due to the blank holder 9 being supported by the hydraulic cylinders 2, 3 only, it can be miniaturized more than an air cylinder.

IPC: B65H7/12
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To detect a duplicate feed by detecting a displaced position of a paper sheet detecting cam by a detector, and judging whether or not paper sheets are carried in duplicate by a judging part from output from the detector and a thickness of the paper sheets supplied to a preset supply passage. SOLUTION: In the case of carrying a thin paper sheet 13a and a paper sheet 13b having a thickness of about twice its thickness, a shape of a paper sheet detecting cam 11 to detect a duplicate feed is formed in a special shape. When a duplicate feed is caused, different output is performed from a detector 12 at carrying time of the paper sheet 13a and at carrying time of the paper sheet 13b. On the other hand, after information on which one of the paper sheets 13a or 13b is carried from a paper sheet housing part is prerecognized in a judging part, the existence of the occurrence of a duplicate feed is judged from this information and output. To put it concretely, when output is not performed from the detector 12, it is judged that a duplicate feed is not caused.

Title: Loose-leaf member for binder-type file
Inventor: SUMINO KATSUHIKO
IPC: B42F3/00
Filed: 1987-08-31
Abstract: PURPOSE:To ensure that loose-leaf members can be easily engaged with binding elements and be hardly disengaged from the binding elements by a construction wherein communicating passages opening to an edge of a loose-leaf member from binding holes in one binding hole group and communicating passages opening to the edge from binding holes in the other binding hole group are slanted relative to the edge so that the corresponding communicating passages in the two groups of the communicating passages are closer to each other on the binding hole side than on the edge side. CONSTITUTION:A loose-leaf paper A for a binder-type file is positioned at an angle to the axes of binding elements 7, and while pressing the paper against the binding elements, the paper is rotated in the center of symmetry S to a parallel position. During this process, the binding elements 7 are relatively moved through slant communicating passages 2 to binding holes 1, whereby the loose-leaf paper A is engaged with the binding elements 7. The communicating passages 2 for first and second binding hole groups B1, B2 divided by the center of symmetry S are slanted relative to an edge of the paper A so that the corresponding communicating passages in the two groups of the communicating passages are closer to each other on the binding hole side than on the edge side. Therefore, engaging functions of the inner edges of the communicating passages 2 and the binding elements 7 ensure that the loose-leaf paper A once engaged with the binding elements 7 can be hardly disengaged from the elements 7 even when being pulled in any slant direction.
