(Prior Art) In a foundry, for example, when a cast cylinder block that has been demolded and has not yet been sufficiently cooled is suspended from a hanger using its bore hole and delivered to a pedestal in the next process line. Direct conveyance using a hoist is also considered, but when hanging the casting on a hanger, a swinging angle occurs between the fulcrum of the hoist and its hook, which is dangerous. Therefore, a cart with a lift table is used to lift the items suspended from the hanger and take them out to a position on the side of the hanger, and then from the cart with a lift table, a hoist is used to deliver the items to an unloading conveyor. The process required a combination of machinery and human power, resulting in inefficient work.

For this reason, a device disclosed in Japanese Patent Application Laid-open No. 49-6679 has been proposed as a device for transferring articles suspended from a hanger to a conveyor. In this device, the hanger is tilted and the article is transferred onto the conveyor by falling.

(Problems to be solved by the invention) However, with the device proposed above, the holding of the articles by the hanger during transfer is unstable, and when the articles fall, they are damaged and are difficult to transfer to the conveyor. There is also the problem of unstable loading.

This idea eliminates the need for human intervention,
To receive an article from a hanger and deliver it to a cradle stably and all at once without damaging the article, and to deliver the article to a drive means for receiving the article suspended from the hanger and a cradle on the carry-out side. It is an object of the present invention to provide a compact delivery device in which a single cylinder device can serve as a driving means for the transfer and transfer of the transfer device.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention delivers the article suspended from a hanger to a carry-out cradle provided on the side in which the end of the hanger extends. This assumes a hanging article delivery device. and,
A cart that moves between the hanger and the carry-out pedestal along the extending direction of the tip of the hanger, and a cart provided on the cart so as to be tiltable forward toward the carry-out cradle around a horizontal axis perpendicular to the moving direction of the cart. , an article having an L-shaped cross section, consisting of a horizontal extrusion plate and a side plate standing upright from the delivery pedestal side of the extrusion plate, and in which the extrusion plate is movable upward along the surface of the side plate relative to the side plate. Ukebe and

Then, the article and the hanger become free, so after removing the hanger from the article while holding the article, the cylinder device is retracted.

Next, after moving the trolley to the carry-out pedestal, the article receiving section is tilted forward by the tilting device. Thereafter, when the cylinder device is extended, the article supported by the tilted side plate and the push-out plate is pushed diagonally upward and finally delivered onto the carry-out pedestal.

(Example) Hereinafter, an example of this invention will be described in detail with reference to the drawings. In addition, in the figure, the left side is the front, the right side is the rear,
The directions perpendicular to the plane of the paper are left and right.

The delivery device 1 includes a cart 4 that moves between a hanger 2 on the rear side and an unloading platform 3 on the front side. The cart 4 has an article receiving section 7 formed by arranging an upright side plate 5 and a horizontal extrusion plate 6 in a substantially L-shaped cross section, and is attached to the article receiving section 7 by a left-right axis 7a along the corner of the article receiving section 7. It is pivotally supported with respect to the truck 4 so as to be tiltable forward.
The push-out plate 6 is configured to be movable upward relative to the side plate 5 by a cylinder device 8. A stopper 9 is provided on the truck 4 in correspondence with the upper part of the push-out plate 6.

The hanger 2 has a substantially L-shape and is configured to be able to suspend and transport the article W to be conveyed (in this embodiment, a cast product of a cylinder block) in the left-right direction.

The carry-out receiving table 3 is a roller conveyor for sending the article W to the next process, but it may have other configurations.

The trolley 4 has wheels 4b pivoted on an underframe 4a at four locations on the front, back, left and right, and moves while being guided on rails 4c laid in the front and back direction. In addition, the trolley 4a
The forward and backward movement of is performed by the expansion and contraction of the moving cylinder device 4d. A gatepost 4e is erected on the trolley 4 with a support 4f, and a stopper 9 is provided at the lower part of the girder of the gatepost 4e.

In the article receiving section 7, a side plate 5 is integrally erected on a base 7b, and a tilting cylinder device 7c as a tilting device is provided between the base 7 and the trolley 4. Due to the extension, the article receiving section 7 is tilted forward. Freely rotating rollers 5a are arranged side by side on the inner surface (right side in the figure) of the side plate 5, and are configured as a free roller conveyor. In addition,
The shaft 7a has one shaft on each left and right between the article receiving part 7 and left and right brackets (not shown) integrally provided on the trolley 4.
They are provided one by one.

The extrusion plate 6 has a guide 6a projecting integrally below it, while a guide roller 7d is rotatably supported on the base 7b, and the extrusion plate 6 can move up and down at right angles to the side plate 5.
