  • Publication number: 20240288592
    Abstract: An X-ray inspection apparatus includes: a conveyance unit; an X-ray irradiation unit that irradiates an article conveyed by the conveyance unit with an X-ray; an X-ray detection unit that detects the X-ray that has transmitted through the article; an inspection unit that generates an X-ray transmission image from the X-ray detected by the X-ray detection unit and inspects the article on the basis of the X-ray transmission image; a housing that houses the X-ray irradiation unit and the X-ray detection unit; a cold air blower that cools air in the housing and guides cold air to the X-ray detection unit via a duct; a monitoring unit that monitors a state of the cold air blower; and a control unit that stops the supply of electric power to the X-ray detection unit in a case where an abnormality in the cold air blower is detected in the monitoring unit.

  • Patent number: 9522414
    Abstract: An inspection system is provided with a weight inspection device, a sorting device, and a frame. The weight inspection device includes a weighing conveyor for conveying a weighing object, and a load cell for weighing the weighing object conveyed by the weighing conveyor, and inspects the weighing object using the result of weighing by the load cell. The sorting device includes an sorting conveyor arranged downstream of the weighing conveyor, a movable member being configured to come in contact with the weighing object conveyed by the sorting conveyor to change a traveling direction of the weighing object, and a cylinder for driving the movable member based on the result of inspection by the weight inspection device so as to cause the movable member to come in contact with the weighing object. The frame supports the weighing conveyor, the load cell, and the movable member.

  • Patent number: 6938677
    Abstract: The invention provides an air-conditioning apparatus that maximizes the space in an operator's cab and provides a comfortable working environment for the operator of a construction machine. The body unit of the air-conditioning apparatus is disposed under the floor surface of the cab, cold air and hot air ducts are connected to the body unit, and routed under the floor of the cab to be passed through the floor surface and taken out into the inside of the cab using cold air and hot air outlets disposed at both left and right sides at the front part of the cab. Also, by providing two evaporators, air of different temperatures can be blown through the left and right outlets.

  • Publication number: 20050173095
    Abstract: The air conditioner capacitor is arranged at the front side of the oil cooler or the radiator against the flow of the cooling air, thereby carrying out maintenance of the oil cooler and/or the radiator at the rear side without removing the air conditioner capacitor arranged at the front side, thus improving maintenance. The turbocharger cooler 11 is structured to change the postures so as to swing up and down between the cooling posture in which the turbocharger cooler 11 is arranged in parallel with the radiator 8 and an open posture in which the turbocharger cooler 11 is arranged such that the front side of the radiator 8 is exposed.

  • Publication number: 20040187509
    Abstract: The object of the present invention is to provide an air-conditioning apparatus so as not to make space in an operator's cab narrow and to bring about a comfortable working environment in the operator's cab when installing an air-conditioning apparatus in a construction machine. For these purposes it is structured that while the body unit 4 of an air-conditioning apparatus is disposed under the floor surface 9 of the cab 1, cold air and hot air ducts 10L, 10R, 11L, 11R which are connected to the body unit, are routed under the floor of the cab and are taken out into the inside of the cab. In addition, the cold air and hot air outlets 10La, 10Ra, 11La, 11Ra are disposed at both left and right sides at the front part of the cab. Also, by providing two evaporators 6L,6R, air of different temperatures can be blown out through the left and right outlets.
