7 Claims.
This invention relates tofurnace discharging machines, one of the objects being to provide a sturdy mechanical device for removing work from a furnace and depositing it on a conveyer. Pref- 5 erably, this device deposits the work on the conveyer with a slight forward urging motion to start it alo-ng. Other objects may be inferred from the following disclosure.
Referring to the accompanying drawing:
Figure l is atop plan.
Figure 2 is a side elevation.
The drawing shows the invention removing work from a continuous sheet pack furnace I and depositing it on a gravity roller-conveyer 2 which, it is assumed, feeds a breakdown mill.
In the present instance the machine includes spaced guiding channels 3 arranged substantially parallel to and below the end of the conveyer 2 adjacent the furnace I. These guides have 20 dropping end portions 3a. A rocking substantially bell-crank mounting member 4 rides in these guiding channels on rollers 5 which form a rocking axis.
This mounting member is constructed with l short and long arms, the short arms being spaced and extending angularly upward towards the furnace I and the long arm extending away therefrom. These short arms mount carrier blades 6 and the long arm is preferably fixed to an endless chain 'I carried by sprockets 8 so as to be substantially alined with the channels 3.
Gne of these sprockets is driven by a motor 9 through a suitable gear reduction unit I and is braked for quick stopping by an electromagnetic i brake II. These arms are, in effect, a carrier for the work.
In operation, the chain I is rotated by the motor 9 so that the carrier blades 6 are reciprocated between points in the furnace I and below the conveyer 2. In the forward motion the long arm of the mounting memberI is raised, because it will then be carried by the upper section of the chain l. Thus, the carrier blade 6 will be moved forwardly in a downward position and may engage beneath the sheet packs moved through the furnace I.
The long lever of the mounting member then rides around the forward sprocket, so that it is moved downwardly and rocks the member. This moves the blades upwardly so that they lift the sheet packs and remove them from the furnace. When the pivotal point of the chain rounds the other sprocket it rocks the long arm of the mounting member upwardly so that the carrier blades drop and deposit the sheet packs on the conveyer.
As the long arm of the mounting member describes an arc around the sprockets it imparts a circular or curvilinear motion to the carrier blades so that when in the furnace they lift the work with an outward drawing motion and when drop- 5 ping below the conveyer 2 with a forward dropping and urging motion, this last giving the packs a slight push o-r urge along the conveyer.
Preferably, the long arm of the mounting member 4 is provided with a roller I2 at its pivotal 10 point with the chain l. This roller runs beneath guides I3 arranged over both straight portions of the chain 1, and is thereby held downwardly so that the chain need not withstand the weight of the sheet packs on the carrier blades.
In the present instance the conveyer 2 is a rather wide one, to accommodate large sheet packs, and is constructed with slots 2a through which the carrier blades pass in their discharging motion. Obviously, this conveyer may be con- 20 structed in various other ways to permit passage of the carrier blades. In addition, limit switches may be used to effect automatic control of the motor 9. If this is done it will probably prove preferable to so: arrange them that the guide blades 6 are always out of the furnace and in a position below the conveyer 2. This will mean that the end of the long arm of the rocking mounting member will be just above the axis of the sprocket 8 most remote from the furnace. 30 Then, in discharging operation, it will make a complete circuit around the other sprocket and back to this` point.
The conveyer system which moves the sheet packs through the continuous furnace I has not been shown and described because it forms no part of the invention and is well known to those familiar with continuous furnaces. The position of the breakdown mill has not been indicated for the same reason.
Although a specific form of this new furnace discharging machine has been shown and described in accordance with the patent statutes, it is not intended to limit the inventive scope exactly thereto, except as defined by the following claims.
I claim:
