Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a simple conveyance device that can convey long, heavy objects such as crankshafts and camshafts without damaging them.

(Prior Art) In order to convey long and heavy items such as crankshafts and camshafts to other locations, a chain conveyor as shown in Japanese Utility Model Publication No. 48-604, or As shown in Japanese Utility Model Publication No. 55-24028, there is one in which conveyance is carried out by raising and lowering one of two rods having serrated teeth arranged at different pitches. However, since all of these devices directly hold and transport the journal part, etc. with the shaft end of the long object exposed, there is a risk that these parts may be damaged during transport. However, when it comes to a wide variety of products produced in small quantities, not only is it not possible to accommodate all types of products, but there is also the problem of unnecessarily overusing equipment.

On the other hand, in order to accommodate such high-mix, low-volume production, long objects are transported by sliding or rolling on inclined rails, which may cause the long objects to stop midway due to the steepness or steepness of the slope. In order to solve these problems, for example, as seen in Japanese Utility Model Publication No. 58-51126, rail A method in which the movement of the workpiece is restricted while moving the chain along the chain has the problem of requiring excessive equipment and increasing manufacturing costs.

(Purpose) This invention was made in view of the above problems,
The purpose is to provide a conveying device with a simple structure that can convey long objects without damaging them.

(Means for Achieving the Object) In other words, in order to achieve the object, the present invention provides an elastic device for placing a long object in the running direction on a trolley that is movably supported by front and rear wheels. A placing part covered with the bed body is provided, and at the front and rear of the cart, a frame-shaped shaft end protruding outward from both ends in the longitudinal direction of the long object placed thereon is provided, and a grip for protecting the shaft end and moving the cart is provided. A simple transport device for long objects with an integrally fixed rod.

(Example) The details of the present invention will be explained below based on the illustrated example.

The drawing shows an embodiment of the present invention configured as a conveying device for a crankshaft. A state in which the supporting plates 3, 3 supporting the journal part a of the W are covered with V-shaped mounting parts 4, 4 provided at the top thereof with elastic bodies 5, 5 made of hard rubber or hard resin. It is erected in

On the other hand, on both sides of this truck body 1, pipes extending forward and backward of the body 1 are integrally fixed as frame members 6, 6, and each extending end thereof is bent upward, and a support plate 3 It is connected by a horizontal bar on the outside passing through the axis of the crankshaft W placed above, and is configured as a frame-shaped gripping rod 7 for protecting the shaft end and moving the cart.

When the crankshaft W is placed on the trolley 1 configured in this manner using a manipulator (not shown), the journal portion a is prevented from metals coming into direct contact with each other due to the elastic bodies 5, 5 made of hard resin or the like. In addition to being placed thereon, it is reliably protected by the gripping rod 7 located outside the shaft end.

And the trolley 1 on which the crankshaft W is mounted
is sent to the next process along the guide rail 10 by the hand of the worker, but this guide rail 10
On the way, there is a weighing device 1 supported by a height-adjustable stand 11 as shown in FIG.
2 is disposed, and in the process of passing over it, the total weight including the conveyance device is measured, and the value is displayed on the display 13 and subjected to a weight check.

Although the present invention has been described above as a device for conveying a crankshaft, the present device can also be applied to conveying long heavy objects such as camshafts and axles.

(Effects) As described above, according to the present invention, since the long object mounting section covered with the elastic material is provided on the cart, the long object can be directly placed on the mounting section via the elastic material. It can be transported without contact.

Moreover, since the trolley body 1 is provided with frame-shaped gripping rods that protrude outward from both ends of the long object in the longitudinal direction, even if a traffic jam occurs during continuous conveyance, the shaft ends of the long object can be held together. Not only can accidents such as damage due to contact be prevented from occurring, but also the frame-shaped gripping rod can prevent the shaft end from coming into contact with other objects during normal manual transportation. can.
