Description

The present invention relates to a method for recovering an object (for example, an empty resin bobbin wound with a wire for semi-automatic arc welding) by touching a liquid (for example, water containing a detergent) more than desired, a tank, a part therefor, It is about tools.

  In order to efficiently recycle resin empty bobbins, etc., on which wires for semi-automatic arc welding are wound, remove foreign materials such as display paper attached to empty bobbins, etc., or adhere rust etc. It is necessary to clean the traces.

  Moistening the paper with water from a water hose and scrubbing the paper, including dirt, such as rust, at the same time with a detergent, etc., is very labor intensive and expensive. In addition, a large amount of water and detergent flows without being reused once and it becomes difficult to collect peeled paper and rust. In addition, in the case where a large amount of empty bobbins and the like are put in a large tank without a partition (for example, a washing tank as in Patent Document 1 below) for reuse without being flowed once, water or detergent ( In the same patent document 1, the waste of the granular material 3) is small, but the state of each empty bobbin etc. in the tank is confirmed, and only the paper that has been moistened and rust has fallen is collected. There was a problem that a lot (5 to 6 pieces) was added to the tank finely, and the lot entered first could not be managed to be collected in advance than the lot entered later.

JP-A-10-309550

  The problem to be solved by the present invention is that it is low-cost and does not cause a large amount of water or detergent to flow once at a time. Is to provide a method, a tank for it, and parts and tools.

In order to solve this problem, the invention of claim 1
An object (including organisms; the same applies hereinafter) is brought into contact with the liquid in the looped tank (1 in FIG. 1), and the object is turned into a liquid while circulating the liquid and the object (2 in FIG. 2) along the loop. Provided is a method for recovering by touching more than desired.
With this loop structure (1), it is possible to ensure that the lot of the object (2) previously put in contact with the liquid more than desired during the movement of the loop, and that the lot that has been put in later is more advanced. It can be recovered.

The invention of claim 2
The liquid is water, and the object is a resin-made empty bobbin (2) in which a wire for welding is wound,
Provided is a method in which the final purpose of touching more than desired is to remove foreign matter (2p) adhering to an empty bobbin.
Thereby, it becomes easy to collect the first bobbin (2) by first-in first-out after touching the water more than desired while adding the empty bobbin (2) as needed.
The method of the present invention can be appropriately implemented by the hollow cylindrical shape of the empty bobbin (2) that is easy to rotate and the degree of buoyancy of the resin with respect to water. It is the same even if an appropriate detergent for moistening paper or the like, dissolving paper or the like, or rusting or the like is added to water.

The invention of claim 3
Provided is a method in which the loop (1) meanders so as to ensure a sufficient path as compared with the installation scale of the tank.
This allows more objects or more time to be processed in one loop.
Loops including meanders can be regularly arranged on a plane as shown in FIG. 1, but irregularly arranged according to the addition of processing steps (when the specific gravity of an object is close to the specific gravity of a liquid) It is also possible to arrange the snakes in a three-dimensional manner so that the snakes wind around the three-dimensional. In the case of a three-dimensional structure, the amount of objects that can be accommodated per tank installation area is greater than that of a flat surface, but it is advantageous, but most of the route on the way is a hose shape (or a snake skin connected in a loop shape). It is advantageous that the (receiving port) and the recovery port are in a state in which an opening (D in FIG. 3) is opened in the hose at the highest position of the three-dimensional body for insertion and accommodation.

Further, according to the invention of claim 4, one worker (1w in FIG. 1) moves (too much or almost) about a plurality of discrete portions (1b in the example of FIG. 1) in the loop path by the meandering. Provide a way to make it easier to work without.
This is realized by, for example, a state in which “a plurality of discrete parts in the loop path” are locally arranged in the loop path without any significant gap (1 in the example of FIG. 1). can do. This is because if an extremely large gap exists, an object or water in the gap cannot be processed or drowned without moving the fixed position, so that work efficiency is deteriorated.
In the loop of FIG. 1 (1 in the example of FIG. 1), the largest separation is suppressed to twice the vertical size of the tank.

Further, the invention of claim 5 provides a method in which the operation that the one worker (1w) does not move is an operation for circulating a liquid or an object along a loop.
As an operation for circulating along this loop, an operation (such as the arrow direction in FIG. 1) in which the liquid or the object is desired to be circulated (the direction may be different depending on a plurality of discrete parts; Possible actions are to push the liquid into the direction you want to circulate (in the direction of the arrow in FIG. 3 etc.), to separate the object from the liquid in the direction you want to circulate (in the direction of the arrow in FIG. 4), etc. It is done.

Further, the invention of claim 6 provides a method in which the work that the one worker does not move is an operation of loading or collecting an object.
The action of throwing an object is an action that does not apply a force for patrol, such as adding from the top in addition to the one accompanied by the above patrol (in the case of throwing F in FIG. 3 or the worker in the example of FIG. 1) (Into a meandering path close to (1w)). This makes it easy to put in the middle of the loop path what needs a little more processing time.
The operation of collecting an object includes an operation that does not apply a force for the circulation, such as simply collecting the object directly above, in addition to the operation accompanied with the above-described circulation. As a result, it is easy to collect what has already been processed in the middle of the loop path (recovery from a meandering path (upper part 1b) close to the worker (1w) in the example of FIG. 1).

The invention according to claim 7 provides a method in which the work that the one worker (1w) does not move is an operation of confirming the state of an object.
The operation of checking is an operation of checking whether the paper or the like is sufficiently moistened by visual observation or rubbing with a hand or scrubber. This facilitates confirmation of completion on the meandering path (upper part of 1b) close to the worker (1w) in the example of FIG. 1, and can eliminate unnecessary processing and improve processing efficiency. .

  The invention of claim 8 provides a method in which the degree of meandering is relaxed at a predetermined location (1b in FIG. 1). As a result, it is possible to perform an operation of making a patrol, an operation in which a machine detects the state of an object, and an operation in which a human or machine inputs or collects an object linearly or on a straight line at the predetermined location. The operation is simplified, the accuracy of the operation is increased, or work efficiency and energy efficiency are increased.

Further, the invention according to claim 9 is directed to an object on the side (in the vicinity of the lower left corner of the basic diagram in FIG. 1) where the liquid flows from the predetermined portion (1b in the basic diagram in FIG. 1) of the loop path. A method is provided in which a receiving port (D, E, F, etc. in FIG. 3) for facilitating the charging is provided.
The receiving port has an opening (D in FIG. 3) when most of the path is closed, a part where the path is partially widened (E in FIG. 3), a part of a charging hopper (or a charging guide) ( It can be realized as F) of FIG.
As a result, the liquid immediately after being efficiently sprinkled at the predetermined location surely pushes the charged object (2) in the circulation direction, and the smooth flow of the object is promoted, and the sufficient length is ensured. This also leads to securing a processing path (from the input point to the collection point is far away in a normal route and from the collection point to the input point is close in a normal route). In addition, the worker (1w) collects an object to be inserted into the receiving port, a work to beat at a predetermined place, and a circulating object flowing to the predetermined place before looking into the straight line at the predetermined place before entering the second round. It is easy to perform the work alone or in cooperation with two or more people depending on the proximity of the predetermined location and the receptacle and the positional relationship.

Further, in the invention of claim 10, on the side (in the vicinity of the lower right corner of the basic diagram of FIG. 1) where the liquid flows to the predetermined part (such as 1 b of the basic diagram of FIG. 1) of the loop path, Provided is a method with a recovery port to facilitate recovery of an object.
The recovery port has an opening when most of the path is closed (D in FIG. 3), a part where the path is partially narrowed (G in FIG. 4), and a part where the path is partially shallow (H in FIG. 4). This can be realized as a portion (I in FIG. 4) in which the degree of meandering of a part of the route is increased.
As a result, the liquid vortex after being efficiently sprinkled at the predetermined location surely attracts the object to be recovered, facilitates the smooth recovery of the object, and has a sufficiently long processing path. (The distance from the entry point to the collection point is normal, and the collection point to the input point is close to the normal route). In addition, the worker (1w) hits at a predetermined position, the object (2) is recovered at the recovery port (D, G, H, I), and the recovery port leaks and flows to the predetermined location. Work to collect the finished object before seeing it in the straight line at the predetermined place and enter the second round, and also to place a new lot in the predetermined place (1b in the basic diagram of FIG. 1 etc.) It is easy to carry out the work to be carried out by one person alone or in cooperation with two or more people by the proximity and positional relationship between the collection port and the predetermined location.

Further, the invention of claim 11 provides a method (such as FIG. 5) in which the depth of the tank is at least twice the height of the object so that more objects (2) are brought into contact with the liquid.
Thus, even when an object rides on another object in the tank, it is possible to reliably process the object that has been picked up by touching the liquid evenly.

Further, the invention of claim 12 is provided with a slope (5b and 5a in FIG. 5) for shallowing a portion where the work is frequently performed in the loop path so that the worker can easily work on the object in the tank. Provide a method.
As a result, even if the tank is deeper than the height of the object, the working area becomes shallow, so the object can be collected, the state of the object can be confirmed, and the force of scooping the liquid can be applied not only to the surface layer but also to the deep layer. It becomes easy to convey.

The invention of claim 13 provides a method of processing so that the fold of the loop path is a gently curved surface (such as 1c in FIG. 1).
As a result, the squeezed force does not collide with the wall perpendicularly, but spreads along the path of the loop without waste, and efficient patrol can be performed.

Moreover, invention of Claim 14 provides the tank (1) for implementing the said method.
The tank formed in this way not only stores and uses water and detergent so that it is not wasted, but also realizes management by first-in first-out of objects by loop, efficient introduction of objects, patrol, status check, Enables collection and handling.

The invention of claim 15 provides parts or tools (partition, table, slope, hopper, liquid scooping tool, object recovery tool) to be added to the tank in order to carry out the above method.
A partition (such as 1p in FIG. 1) is an iron plate, a resin plate, a wooden plate, etc. for forming a path in a tank that is not a path, and is fixed to the bottom of the tank by welding, welding, nailing, etc. Can be used.
The platform (5a in FIG. 5) is used by being submerged or being fixed to the bottom of the tank in order to make a part of the path of the tank shallow.
Slopes (such as 5b in FIG. 5) are used to make the both ends of the table gentle, and to make the circulation easier by curving the right angle formed by the tank and the partition.
A hopper (such as 3f in FIG. 3) is used by welding, nailing, or the like to the tank to form an inlet.
As the liquid drilling tool (not shown), a coconut tree or a resin for rolling the liquid can be used.
As the object recovery tool (such as that held by the worker 1w in FIGS. 1 and 4), a net with a handle or the like can be used. Also, the liquid scooping tool and the object recovery tool are integrated (one handle is a liquid scooping tool and the other is an object recovery tool. It can also be realized by using a structure.

  As described above, it is possible to ensure that the lot of the object (2) put in first comes in contact with the liquid more than desired during the movement of the loop, and can be recovered in advance than the lot put in later. become able to. In addition, the effects described above are provided for each invention.
