Patent number: 6110089Abstract: A bag making and packaging machine has a pair of transverse sealing members on opposite sides of a film path for transversely sealing a bag-making film moving longitudinally along this path. A pair of support members supports these transverse sealing members and is driven so as to bring the transverse sealing members towards each other to contact with the film and away to separate them from each other. At least one elastic member is interposed between at least one of the support members and the corresponding one of the transverse sealing members. This elastic member is in a contracted condition when the transverse sealing members are in contact with the film on the film path and thereby applying on the film a sealing pressure corresponding to the distance by which the elastic member is contracted.Type: GrantFiled: September 12, 1997Date of Patent: August 29, 2000Assignee: Ishida Co., Ltd.Inventors: Hirokazu Hatozaki, Setsuo Haze

Patent number: 4666002Abstract: A system for compelling weighing machines to participate in a combinatorial weighing operation operates by updating the number of times a weighing machine is not selected for a combination, whenever a single combination giving a total weight value within preset allowable limits is obtained by combinatorial computation. The number for a weighing machine which is selected for a combination, is reset whenever a single combination giving a total weight value within preset allowable limits is obtained by combinatorial computation. A weighing machine, which has not discharged its articles for a large number of cycles, is compelled to participate in a combinatorial computation.Type: GrantFiled: April 27, 1984Date of Patent: May 19, 1987Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventor: Setsuo Haze

Patent number: 4661920Abstract: A method and apparatus for automatically adjusting the zero point of a weighing machine includes producing, in the form of a digital value, an initial zero-point correction value when the weighing machine is free of a load. The difference value between an unloaded weight value, which is produced by the unloaded weighing machine, and a value obtained by converting the digital value into an analog value, is calculated. The difference value is compared with a preset value, and digital values are sequentially converted in accordance with the result of the comparison operation to render the difference value equal, or nearly equal, to the preset value.Type: GrantFiled: April 27, 1984Date of Patent: April 28, 1987Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventor: Setsuo Haze

Patent number: 4661917Abstract: A mixing combinatorial counting and weighing method and apparatus for packaging a wide variety of articles in a single pack, wherein the numbers or ratio of the candies are designated. Prescribed numbers of the articles, which are high in unit price or large in volume, are discharged by using article supply units and combinatorial counting units. The weight of the articles discharged is stored, and this stored weight is subtracted from a weight set for the pack to compute the difference. Then, inexpensive articles are discharged using a combinatorial weighing unit, wherein the weight of the articles discharged is equivalent to the computed difference, and the articles discharged from the respective units are collected. Thus, a wide variety of articles can be introduced into a single pack at a prescribed ratio and, at the same time, the total weight of the pack can be held within established limits.Type: GrantFiled: November 18, 1983Date of Patent: April 28, 1987Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventors: Setsuo Haze, Yugo Fujitani

Patent number: 4553616Abstract: Weighing conditions, depending on the kind of article being weighed and on the target value for the weighing operation, are entered as a set of reserved values through a data input unit, and the set of reserved values is written into a memory of a storage unit by a write control unit. The storage unit includes a plurality of memories, each of which stores a different set of reserved values. A read control unit, in response to an input from the data input unit, selects a required set of reserved values from the corresponding memory of the storage unit, and applies prescribed ones of these values to a combinatorial computation control unit and feeder drive units. Therefore, when it is necessary to reset weighing conditions whenever there is a change in the kind of article being weighed or in the target value, the resetting operation is performed merely by reading the desired weighing conditions, namely the set of reserved values, from memory.Type: GrantFiled: August 12, 1983Date of Patent: November 19, 1985Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventor: Setsuo Haze

Patent number: 4508185Abstract: A combinatorial weighing method which includes steps of dividing a target weight value, set for articles which are to be weighed out, into a plurality of target values, and executing combinatorial computations with respect to each of the target values on the basis of the weight values of the articles fed into a number of weighing machines, so that weighing hoppers selected with respect to each target value do not include weighing machines selected with respect to the other target values. An error between the total weight value of the combination of articles selected as a result of the previous combinatorial computations and the target value for that particular combinatorial computation is formed. The error is added to the target value for the next combinatorial computation and then the next combinatorial computation is executed. After completing the combinatorial computations with respect to all of the target values, the articles are discharged from the selected weighing machines.Type: GrantFiled: September 3, 1982Date of Patent: April 2, 1985Assignee: Kabushiki Kaisha Ishida Koki SeisakusuoInventors: Kazukiyo Minamida, Setsuo Haze, Seiji Yamada
