Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an apparatus for continuously transporting and cleaning iron plate sheets one by one, and in particular to an iron plate cleaning and transporting apparatus that enables continuous transport of iron plate sheets without stopping the line even when a malfunction occurs in the cleaning process.

[Conventional technology] Various technologies have been devised to convey iron plate sheets, but none of them have been equipped with a cleaning device within the conveyance process of a continuous line. The common method was to transport the sheets and process them in a separate process. Also, special public service in 1984.
There is also a conventional technique disclosed in Publication No. 12574, which improves work efficiency by continuously and automatically supplying metal plates, printing or painting them, and automatically receiving metal plates after these operations have been completed. This is how it was done.

[The problem that the idea aims to solve]

In the above-mentioned prior art, various measures have been taken for automatic conveyance and removal of metal plates, etc., but none have been found in which a cleaning device is installed within the process. In addition, the process in which failures are relatively common in automatic loading/unloading equipment, including cleaning equipment, is the cleaning process. For example, the workpiece (iron plate) may interfere with the roller and slip into the roller, or the brushes, cloth, etc. that cover the roller may wear out. or In order to accommodate this, there may be cases where the continuous line must be stopped. Therefore, even if the cleaning process is provided in a continuous line, a problem arises in that the entire apparatus cannot be operated continuously in the event of a failure. As mentioned above, the cleaning process can be performed in a separate process, so even if the cleaning equipment in the continuous line breaks down, the entire equipment can be operated continuously, and the iron sheets in between can be processed in a separate process. Working efficiency will be improved by continuous operation.

The present invention was developed with the above points in mind, and it allows the loading and unloading and cleaning of iron plates to be carried out in a continuous line, and even if the cleaning equipment breaks down, the operation of the entire equipment does not have to be stopped. The object of the present invention is to provide an iron plate cleaning and conveying device that is capable of continuous operation.

[Means to solve the problem]

To this end, the present invention has a loading station that inputs pallets loaded with iron plate sheets cut into predetermined shapes, and a structure that peels off the iron plates one by one from the loaded pallets and carries them out to the next process side. A sheet cleaning machine equipped with a stripping station where the iron plates are removed and various rollers for cleaning the iron plates that have been introduced is installed so that they can be carried in and out, and the iron plates that have been introduced from the previous process are placed in the space behind the sheet washing machine that is carried out. A cleaning station that is equipped with a conveying means for conveying to the next process side, a discharging station that centers the iron plate carried in from the cleaning station and discharges it to the next process side, and a stripping station that allows the iron plate to be conveyed to the next process side. This apparatus constitutes an iron plate cleaning and conveying apparatus which is provided with an empty pallet return station for returning empty iron plate sheets and empty pallets.

[Effect]

The iron plate sheets are stacked on pallets and fed from the feeding station into the peeling station. At the peeling station, the iron sheets are peeled off from the pallet one by one and sent to the cleaning station for the next process. In this case, in order to prevent, for example, two iron plates from being sent to the next process with their adhesion due to oil adhesion, a detection means is provided to ensure that each sheet is conveyed to the next process one by one. The two attached iron plates and the empty pallet are sent to the empty pallet return station. The iron plate sheet sent into the sheet washing machine of the washing station is thoroughly washed here and then sent to the delivery station. At the unloading station, the iron plate sheet is sent to the next process, such as a press machine, in a centered and oriented state. If the sheet cleaning machine breaks down during the above continuous process, the sheet cleaning machine is carried out of the cleaning station. A conveyance means is automatically installed in the space after the sheet washer that is carried out to act as a bridge between the peeling station in the previous process and the payout station in the next process, and the iron plate sheet is continuously unprocessed. will be transported to.

etc., in the return direction. The empty pallet 8 and the iron plate sheets 7 in the returned iron plate guide 28 are carried out in a predetermined case by a forklift (not shown) or the like.

Next, the operation of this embodiment will be explained in more detail.

The iron plate sheet 7 cut into a predetermined shape is loaded onto a pallet 8 at a location outside the iron plate cleaning and conveying device 1,
It is placed on the chain conveyor 13 of the input station 2 by a forklift or the like. Prior to this, the first pallet whose iron plate sheet 7 has disappeared is confirmed by a control means (not shown) that the iron plate sheet 7 has disappeared, and the empty pallet 8 is moved to the locking fitting 64 and the chain conveyor as described above. 65
The empty pallet is carried out to the return station 6, and then moved to another location by a forklift or the like, where a new sheet of iron plate 7 is loaded.

A chain conveyor is driven by the servo motor 14 from the input station 2 to input a new pallet 8 loaded with iron plate sheets 7 into the space in the peeling station 3 where the empty pallet 8 has disappeared. Next, the lifting cylinder 26 is actuated to lower the lifting device 24, and the suction cup 25 picks up the iron plate sheets 7 one by one. When the lifting device 24 rises, the iron plate sheet 7 comes into contact with the magnetic conveyor 21, is transferred to the magnetic conveyor 21 side, and is conveyed to the next washing station 4 side. Washing station 4
The pinch rollers 33 bite into the iron plate sheet 7 and introduce it into the sheet cleaning machine 9. When two or more iron plate sheets 7 are lifted up at the same time due to oil adhesion when the iron plate sheets 7 are loaded on the peeling station 3, these two or more iron plate sheets 7 are attached to the cleaning station 4 side. The DB switch 27 detects the thickness so that it will not be introduced. When it is detected that the thickness of the iron plate sheet 7 to be introduced into the washing station 4 is two or more sheets, the magnetic conveyor 21 is reversed by a control means (not shown), and the iron plate sheet 7 is returned to the empty pallet return station. It is returned to the iron plate stocker 28 and pooled. The iron plate sheets 7 that are normally sent one by one are sent to the sheet cleaning machine 9.
It bites into the pinch roller 33 and is then held by the brush roller 34 for cleaning the iron plate sheet 7.
Cleaned with a brush. Next, the cleaning liquid and the like adhering to the iron plate sheet 7 that has been successively applied to the two sets of linker rollers 35 and 36 is completely removed. As described above, the pressure cylinders 37, 38, 39, and 40 adjust the dimensions between the upper and lower rollers to ensure that the iron sheet 7 is washed reliably and smoothly. Of course, even if the iron plate sheet 7 gets caught inside the rollers, each upper roller 3 will be removed by the cylinder 37 etc.
3a etc. can be lifted and opened. The iron plate sheet 7 that has been cleaned is sent to the delivery station 5 by the rotation of the ringer roller 36, but prior to this, the roller conveyor 49 lowers its tip side around the fulcrum pin 51. It is held in a tilted position. As a result, the iron sheet loaded into the delivery station 5 rolls on the roller conveyor 49 and stops when it hits the front stopper 53. Here, the guide portions 56, 56, and 57 of the centering guide come to a position where they come into contact with the iron plate sheet 7, and the center of the iron plate sheet 7 is positioned. Next, the shift member 54 is lifted by the lift cylinder 55, and the roller conveyor 49 is swung around the fulcrum pin 51.
The roller conveyor 49 is held horizontally. Here, the suction cup 63 of the arm 62 of the transport loader 60 is attracted to the iron plate sheet 7. After the stopper 53 is brought down by the action of the cylinder 52, the transport loader 60 is moved in the unloading direction via the reducer 61 by driving the motor 62, and along with this, the iron plate sheet 7 sucked by the suction cup 63 is unloaded. move in the direction. As a result, the iron plate sheet 7 is supplied to the next process, for example, to a press machine. Here, the guide members 56 and 57 of the centering guide are returned to their original positions, the stopper 53 is also returned to its original state, and the roller conveyor 4
9 is also tilted downward in preparation for feeding the next iron plate sheet 7.

If the sheet cleaning machine 9 breaks down, the entire sheet cleaning machine 9 can be operated by driving the motor 31.
The cleaning station 4 is taken out along the rail 29 and repaired. At the same time, the lifting cylinder 45
As a result of this operation, the elevating magnetic conveyor 43 descends while the guide roller 46 is guided by the guide frame 47, descends to the same height as the magnetic conveyor 21 of the peeling station 3, and is positioned on the conveyance path of the iron plate sheet 7. Moving. The elevating magnetic conveyor 43 is driven by a conveyor drive motor 44.
Accordingly, the iron plate sheet 7 introduced from the peeling station 3 in the previous process to the cleaning station 4 side is sent by the elevating magnetic conveyor 43 to the payout station 5 side in the next process. Therefore, even if the sheet washer 9 breaks down, the iron sheet 7 will continue to be conveyed.

As described above, the frame body 11 is supported by the large wheels 12, allowing the iron plate cleaning and conveying apparatus 1 to be moved to another location. This is because the iron plate cleaning and conveying device 1 gets in the way when replacing molds in a press machine or the like in the next process, and the work is easier if it is moved.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the process from loading, peeling, washing, and discharging of iron plate sheets is performed consistently and continuously, and even in the event of a failure of the sheet washing machine, the iron plate sheets can be continuously removed. It is possible to improve work efficiency without stopping the entire equipment.
