Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for transferring a red-hot casting product after casting and unframing to a hanger hook of a trolley conveyor, which is a means for transporting the cast product.

[Conventional technology]

Conventionally, in iron foundries, as a means of transporting red-hot cast products after casting and fracturing to the next process for the purpose of cooling, space can be used effectively, the transport route can be freely selected, and it is relatively simple. In many cases, inexpensive trolley conveyors are used. This red-hot cast article has an amorphous shape, and its weight, posture, and position are arbitrary. Therefore, there is no technology to transfer it by repeating a constant operation, as in the well-known article transfer device 53-36231. It cannot be applied and relies on manual work.

[Problem that the invention seeks to solve]

The above work is performed at high temperatures due to the radiant heat of the red-hot castings, and
Since this process is carried out in an adverse environment with a lot of foundry sand dust, there are problems such as a decrease in work efficiency.

An object of the present invention is to provide a device for transferring red-hot castings, which are irregularly shaped and have arbitrary postures and positions, onto a trolley conveyor, thereby freeing workers from a bad environment and improving work efficiency. .

In order to achieve the above object, in the present invention, pulse transmitters are provided on the drive shafts of the conveyor that supplies the red-hot foundry and the conveyor that conveys the red-hot foundry after being transferred, and pulse transmitters are provided in parallel to the traveling direction of each conveyor. A pulse transmitter is installed in the travel motor of the transfer device that can move the trolley conveyor, and the guide rail is horizontal in the part related to the transfer work of the trolley conveyor, and the guide rail is inclined in front and behind it, and a hanger is installed in the initial part of the horizontal part. A detector is installed to detect the passage of the hook, a grip detector is installed on the grip of the transfer device so that it can be controlled by a control device such as a computer, a tension device using a spring spring is installed on the trolley chain, and a wire rope is installed. A constant tension is applied to the hanger hook through the
They adopted a technical method of operating the transfer device mainly by operating a joystick lever while visually observing it in the control room.

[For production]

With this configuration, an operator can
While visually observing the red-hot casting area for transfer, use the joystick lever to move the transfer device to the vicinity of the red-hot casting area, and when you start it, the transfer device runs in synchronization with the trolley conveyor, and is constantly controlled by the control device. The transfer device automatically grasps the hanger hook located closest to the red-hot foundry whose position is being controlled, and then automatically runs in synchronization with the conveyor that supplies the red-hot foundry, so the operator can use the joystick to By operating the lever, the hanger hook can be easily guided and hung in the red-hot casting world.

Next, when the grip on the hanger hook is released, the tension device attached to the trolley conveyor prevents it from separating from the hanging red-hot casting, so that it is lifted up as the trolley conveyor moves down the slope and becomes an irregular shape. It becomes possible to transfer red-hot castings of any orientation and position from the supply conveyor to the trolley conveyor.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. Figure 1 is a plan view of the transfer section, Figure 2 is a side view, and Figure 3 is a side view of the transfer section.
The figure is a front view of the transfer device 100, with the transfer device 100 not shown.

A pulse transmitter 301, 201 is installed on each drive shaft of the conveyor 300 that supplies the red-hot foundry A and the trolley conveyor 200 installed above the conveyor 300 so as to proceed in the same direction as the conveyor 300. 300,20
A transfer device 100 that runs parallel to the conveyors 300, 200 is installed on the side of the conveyor 0, and a travel motor 101 is equipped with a pulse transmitter 102, and each signal is sent to a control device (not shown) such as a computer. ) to transmit, store, and perform calculations. The transfer device 100 is composed of a traveling truck 103 and a robot 104, and is guided by traveling wheels 105 attached to four locations on the truck and side rollers 106 attached to two locations on one side, and is guided by a traveling motor on a traveling rail 107. It is configured to be able to freely travel in both directions via a pinion 108 attached to the end of the output shaft 101 and a rack 120 attached to a traveling frame 109. Furthermore, a grip 122 for grasping the hanger hook 202 is attached to the wrist 121 of the robot 104 portion, and a detector 123 for confirming the grip of the hanger hook 202 is equipped.

Further, the trolley conveyor 200 has a guide rail 203 that is composed of a horizontal area a where the transfer is performed, an inclined area that supplies the hanger hook 202, and an inclined area C that lifts the hanger hook 202 after the transfer. erected,
A detector 204 for detecting passage of the hanger hook 202 is installed at an initial portion d of the horizontal portion a, and the detection signal is input to the control device. And hanger hook 20
2 is the trolley chain 2 via the wire row 1205.
The tension device 206 attached to the attachment 209 of the trolley chain 208 is fastened to the attachment 209 of the trolley chain 208 via the suspension short link chain 207 in a state in which a tension device 206 is always applied with a tensile force.

Next, to explain the transfer operation in this configuration, the worker:
The transfer device 100 is moved by operating the joystick lever 401 on the operation panel while visually observing the red-hot castings A after being disassembled being transported in an arbitrary position and posture on the supply conveyor 300. After moving it to the vicinity of the red-hot casting A to be loaded, when the pusher switch (not shown) for the gripping command is pressed, the transfer device works OO, and the pulse generator 102 of the transfer device itself and the trolley conveyor are activated. The control device compares and calculates the signals from the pulse generator 201 of the trolley conveyor 200, and the signals from the pulse generator 201 of the trolley conveyor and the hanger passage detector 204 are transmitted in the control device. By processing, the hanger hook 202 located closest to the transfer device is automatically grasped, and then the synchronous movement with the trolley conveyor is automatically transferred to the supply conveyor 300 based on the signal from the grasp confirmation detector 123. It is possible to switch to synchronous running.

Next, by operating the joystick lever 401, the worker visually guides the hanger hook 202 held by the grip 122 of the transfer device to the red-hot cast article A in any position and orientation, and hangs it. When this is completed, by pressing a grip release push button switch (not shown), the grip 122 is released and at the same time, the posture of the transfer device itself can be automatically returned to the original posture in which the hanger hook 202 can be gripped. As the trolley conveyor 200 advances, the hanger hook 202 hung on the red-hot casting product A is gradually lifted up at the inclined portion C without being separated from the red-hot casting product A due to the tensile force of the tensioning device 206 due to the action of a spring spring, and is supplied. The transfer operation from the conveyor 300 is completed.

In the above example, when the article is relatively heavy, the article is grasped by the hanger hook of the trolley conveyor and hung on the article.On the other hand, when the article is relatively light, the article is grasped and hung on the hanger hook of the trolley conveyor. , it is also applicable to the example of hanging on a hanger hook.
