Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport device useful for transporting objects such as electrode plates (particularly anodes) used in electrolysis of non-ferrous metals.

In electrolytic refining of non-ferrous metals such as copper and lead, when loading and unloading electrode plates (especially relatively heavy anode plates) into and out of the electrolytic tank, there is a time lag between the previous and subsequent processing steps. It is necessary to stock and transport parts.

Therefore, a stock conveyor has conventionally been used to organize and stock an appropriate number of electrode plates.

However, in order to carry out the work smoothly, it is necessary to stock a large amount of electrode plates, so a long stock conveyor must be installed, but if a large number of electrode plates are arranged on such a long stock conveyor, As the weight increases, the structure must be strengthened and the driving force must be increased, resulting in a significant increase in costs.

In order to solve this problem, the structure of the stock conveyor can be simplified by arranging several stock conveyors and installing relay transport carts that automatically run between them, which eliminates the need for extra large driving force. The present applicant has already provided a transportation device that can efficiently and accurately organize, stock, and transport electrode plates and similar objects without using the electrode plates [Japanese Patent Publication No. 51-1
No. 2912 (Japanese Patent Application No. 45-47782)].

However, although the above-mentioned problems were solved by the invention, it was found that two problems described below occur when transporting the anode.

One of the problems is with the chain conveyor.

As shown in Figures 1 to 3, the conventional technology
According to No. 912), the anode 5 is lifted by hooking the end of the ear part 5a by the hook 12 of the relay carrier 4 and transferred onto the secondary conveyor 2, so that the base of the ear part 5a is It had no choice but to be placed on chain conveyor 1 or 2.

However, although the tip of the ear portion 5a of this anode 5 is made into a horizontal plane by an anode straightening machine, the base portion (shown with hatching) has a draft angle to facilitate removal from the mold during casting. It is considered to be a slope.

Therefore, as the anode 5 hangs only on the inner link plate 6' as shown in FIG. 3, the rollers 13 and roller receivers 14 of the chain conveyor 1' become uneven and wear out, and eventually the chain conveyor comes off. There is a risk of causing an accident such as damage.

Furthermore, another problem lies with the relay transport trolley 4.

As shown in FIG. 4, there is a gap between the running rail 3' and the wheel 9', and since the vehicle runs with several tons of anodes 5 suspended at once, the wheel 9' and the running rail 9' Meandering occurs due to manufacturing or installation errors such as .

This meandering of the relay carrier may cause the anode hooked on the hook to fall or shift position, which is not only dangerous but also requires equipment and steps to correct the position of the anode.

If there is a risk that the conveyor may come off or the anode may fall, it becomes difficult to ensure safe and smooth transportation of the anode and to manage maintenance.

The present invention improves the invention disclosed in Japanese Patent Publication No. 51-12912 so that when transporting an anode or a similar object to be transported, the rear anode that has come off the conveyor does not fall, thereby safely and smoothly transporting the anode and the like. It is an object of the present invention to provide a transport device capable of transporting a similar object to be transported.

The configuration of the present invention to achieve such an objective is to run on a traveling rail suspended between a plurality of adjacent chain conveyors and to transport objects on one chain conveyor to the other chain conveyor. In a device for transporting objects while stocking them using a relay transport cart for transferring onto a chain conveyor, a support plate is provided between each link plate of the chain conveyor to straddle these, and the center portion of the support plate is raised. The object to be transported is supported at the center between the link plates, while the contact surface of the running wheel that straddles between the chain conveyors is formed into a mountain shape, and the wheels of the relay transport cart are arranged in the shape of a mountain. It is characterized by a drum shape that fits into the contact surface of the running rail.

The configuration of the present invention will be explained in detail below based on a specific example shown in the drawings.

In this specific example, the object to be transported is an anode.

First, to explain the outline of the transportation device according to the present invention, this transportation device consists of a chain conveyor 1 for primary stock, a chain conveyor 2 for secondary stock, and a running rail 3 installed so as to span between them. The conveyor truck 4 is configured to run on a chain conveyor 1 for primary stock and transfer an object to be transported (hereinafter referred to as an anode) 5 on a chain conveyor 1 for secondary stock onto a chain conveyor 2 for secondary stock.

Chain conveyor 1, 2 for above-next and secondary stock
As shown in FIGS. 5 and 6, the roller chain constituting the roller chain is provided with a support member 7 that spans between the link plates 6 and 6, either by bending the link plate 6 itself or by using a separate member. ing.

The support member 7 has a raised central portion so as to support the anode 5 approximately at the center of the link plate 6.

The protrusions can be made by, for example, attaching a support member 7' formed into a mouth shape using a separate member as shown in FIG. 6, or by bending the link plate 6 or using a separate member as shown in FIG. This is done by screwing a plate 8 having a triangular cross section onto a flat support member 7 provided by welding.

Further, in order to allow the relay transport vehicle 4 to travel straight without meandering, the contact surface 3a of the traveling rail 3 is formed in the shape of a medium-height mountain, while the wheels 9 of the relay transport vehicle 4 are formed in the shape of a mountain with a medium height. They are shaped like a drum so that they fit together.

Furthermore, in order to prevent oil and other foreign matter adhering to the running rail 3 and wheels 9 from deteriorating the adhesion between the wheels 9 and the running rail 3 and causing meandering, a groove is provided in the center of the wheel 9 as a place for foreign matter to escape. 10 is cut off.

Further, a detection device (not shown) is attached to the secondary stock chain conveyor 1, which detects when the leading end of the anode 5 reaches the discharge part of the primary stock chain conveyor 1 and stops the movement of the anode 5. A detection tool (not shown) is also attached to the relay transport vehicle 4 to detect the above-mentioned leading anode 5, stop the relay transport vehicle 4 near it, and activate the transfer tool 11.

The transfer tool 11 has a hook 12 attached to the tip of the piston rod of a hydraulic cylinder, and has a hook 12 attached to the tip of the piston rod of the hydraulic cylinder.
It is provided so that it can be held and lifted from the left and right by the aforementioned hooks 12.

In addition, other detection devices (not shown) are attached to the relay transport cart 4 and the chain conveyor 2 for secondary stock, and there is a space for transferring the anode 5 onto the chain conveyor 2 for secondary stock. The anode 5 is arranged to be transferred immediately after detecting that the anode 5 is being moved.

With this structure, even if the anodes 5 are on both the primary and secondary stock chain conveyors 1 and 2 and their speeds are different, the anodes 5 will get stuck, run out, or fall off the conveyors 1 and 2. The anode can be transported smoothly between the two stock chain conveyors 1 and 2 without any waste.

In particular, since the roller chain constituting the stock chain conveyor 1, 2 is provided with a support member 7 or 7' formed to span between both link plates 6 and 6 and have a raised central portion, Even if the ear part of the anode 5 consisting of an inclined surface is placed, it can be stopped at the center between the link plates, so that the load is applied equally to both link plates and the roller chain does not tilt.

Therefore, there is no risk of the rollers coming off during travel, or uneven wear or damage to the rollers and roller receivers.

In addition, the contact surface 3a of the running rail 3 and the wheels 9 of the relay transportation cart 4 are formed into a chevron shape and a drum shape that fits thereto to cancel out the force in the left and right direction that acts between the running rail 3 and the wheels 9. Since the wheels are arranged so that they move straight while closely touching each other, there is no possibility that the relay transport vehicle 4 will meander.

Therefore, the anode 5 will not fall or the position of the anode 5 will not shift.

Thus, safe and smooth transportation of the anode can be ensured and the life of the device can be extended.

In this specific example, the object to be transported is an anode, but it goes without saying that the present invention is not limited to this.
