Description

An application has been submitted for an exception to the loss of novelty. This invention relates to a conveying device, and more specifically, to a conveying device capable of conveying objects that are substantially cylindrical or substantially cylindrical in shape. Conventionally, there are transport devices for carrying gas cylinders (hereinafter referred to as "cylinder transport devices"). Conventional cylinder transport devices are configured as carts that can hold cylinders in a nearly vertical position and transport them in that state (see, for example, Patent Document 1). Patent No. 7507520 This is a front right side plan perspective view of the first embodiment of the present invention.This is a planar perspective view of the rear left side of the first embodiment of the present invention.This is a right side view of the first embodiment of the present invention.This is a bottom view of the first embodiment of the present invention.This is a front right side planar perspective view of the second embodiment of the present invention.This is a planar perspective view of the rear left side of the second embodiment of the present invention.This is a front view of a second embodiment of the present invention.This is a right side view of a second embodiment of the present invention.This is a plan view of a second embodiment of the present invention. A first embodiment of this invention will be described with reference to Figures 1 to 4. The conveying device 1 comprises a frame 2 and a gripping means 3 (hereinafter referred to as gripping means 3A). In this embodiment, the conveying device 1 further comprises a lifting means 4. The frame 2 has a base 5 and a support portion 6 erected on the base 5. Wheels 7 are attached to the base 5 as means of moving the transport means 1. In this embodiment, the wheels 7 have a swivel wheel 7A at the base end and a fixed wheel 7B at the tip end. A floor lock 8 is provided between the two swivel wheels 7A to prevent the transport device 1 from moving from its position. The gripping means 3A is provided to grip a transported object B, such as a gas cylinder, which is substantially cylindrical or cylindrical in shape, and is also provided to hold the transported object B in an inverted position. The gripping means 3A has a gripping portion 9. The gripping portion 9 has a pair of arm portions 10, and in this embodiment, it further has a receiving device 11, so that the transported object B can be gripped at three points: the arm portions 10, the receiving device 11, and the gripping means 3A. The arm portion 10 is provided so that its position can be changed according to the outer diameter D of the object B to be conveyed. In this embodiment, the arm portion 10 is capable of holding the object B in an overturned state by cradling it from above. The locking portion 12 that contacts the object B is provided with a buffer 13 made of elastomer or the like to prevent the object B from being damaged by the arm portion 10. Furthermore, the arm portion 10 is provided so as to be slidable on the sliding body 14 and is connected to a sliding means 15 provided for sliding the arm portion 10. In this embodiment, the sliding means 15 includes a screw rod 16 and a sliding handle 18 for rotating the screw rod 16 around its axis. The screw rod 16 is screwed into the arm portion 10, and by rotating the screw rod 16, the arm portion 10 moves axially, thereby causing the arm portion 10 to slide on the object to be slid 14. The receiving device 11, like the arm portion 10, is equipped with a buffer 13 at the portion that contacts the object to be conveyed B. The amount of its protrusion L is adjustable according to the diameter of the object to be conveyed B, and a handle 18 is provided for adjusting the protrusion amount L. The lifting mechanism 4 is provided to allow the gripping mechanism 3A to be raised and lowered. In this embodiment, the lifting mechanism 4 is installed on the support portion 6 of the frame 2, and by turning the lifting handle 19, the gripping mechanism 3A is raised and lowered by a winch (not shown) and a pulley 20. The presence of the lifting mechanism 4 makes it easier to load the object to be transported B onto the transport mechanism 1 by lowering the gripping mechanism 3A to a low position, gripping the object to be transported B with the gripping mechanism 3A, and then raising or lowering it to the appropriate position. Therefore, in the conveying means 1 of this embodiment, the arm portion 10 of the gripping means 3A is designed to hold the object B being conveyed in an overturned state, thereby providing a conveying device that can transport the object B while it is in an overturned position. A second embodiment of the present invention will be described with reference to Figures 5 to 9. The difference from the first embodiment is that gripping means 3B is provided instead of gripping means 3A, and a rotating means 21 is also provided. Components indicated by
