[Conventional technology]

Traditionally, for example, a bar was used to remove burrs generated on plate materials during press working. As a deburring device, the deburring wheel rotates perpendicular to the feeding direction of the plate workpiece. A deburring device equipped with this is known. However, such conventional deburring equipment The system uses a deburring holder that rotates at high speed against the workpiece being conveyed on a conveyor device. Deburring is performed by bringing the eel into contact with the workpiece. Deburring is carried out in a dry manner without supplying any water or the like near the contact point. Because the processing was carried out, the dust generated during the deburring process was carried away by the processing machine. To prevent this, a separate dust collection device should be installed. This increases costs and requires separate installation space for the dust collector. There were some issues that needed to be addressed. In addition, dust generated during deburring may be removed from the workpiece. A post-processing process is required to remove dust because it is transported with the particles still attached. This was also a factor in increasing costs.

0003 In addition, since it is a dry deburring process, frictional heat during the deburring process causes a large amount of damage. This generates a lot of heat, which has a negative effect on the workpiece, causing material deformation and deburring wheels. It is not possible to grind a large amount at one time, and this may cause burn-in. If it is necessary to perform large deburring work for Problems that require deburring work and cannot improve deburring work efficiency. There was an issue. Furthermore, in dry deburring work, the workpiece and deburring wheel are Due to the large coefficient of friction between It was.

0004 Therefore, in order to perform wet deburring, the contact between the deburring wheel and the workpiece is Wet deburring involves spraying water near the part using a water distribution method. devices are being proposed. The wet bath proposed in this way The deburring device is used to dry and remove moisture from the workpiece after wet deburring. For this purpose, a draining roller is installed downstream of the deburring wheel to drain the workpiece. The system is equipped with a hot air supply device that blows warm air onto the workpiece to dry moisture. was.

[0005]

[Problem that the idea aims to solve]

However, the drying equipment of the wet deburring equipment proposed in this way is particularly The hot air supply device uses a heater that warms the air and a plate workpiece to blow hot air onto the workpiece. Heaters are required in two places, including the heater that heats the tank, and the energy consumption is large. There is a problem. In addition, the air heated by the heater is blown out through the duct. There is heat loss while passing through the duct because it has to be guided through the duct and sprayed onto the workpiece. However, there is a problem in that it is not possible to blow hot air at a sufficiently high temperature. In addition, warm air In order to blow out the air, it is necessary to maintain contact with the heater for a sufficient period of time, so the wind speed must be increased. Therefore, when spraying on the workpiece, make sure to spray enough moisture. As a result, the heater cannot provide enough momentum to send the object flying. There is a lot of water that needs to be evaporated, and stains appear after the water evaporates from the workpiece. Some problems remain.

[0006] This idea was devised in view of these conventional problems, and it In addition, it is generally a drying device for wet processing equipment that performs wet machining. A drying system for wet processing equipment that is low in cost and can effectively dry and remove moisture. The purpose is to provide a

[0007]

[Means to solve the problem]

This idea uses machining methods to process workpieces that are transported on a table. When performing the process, water distribution means is applied to the area where the machining means comes into contact with the workpiece. Wet processing is performed by sprinkling water on the workpiece, and the workpiece is dried after this wet processing. In the drying device of wet processing equipment, processed workpieces are transported on a table. A draining roller that drains water from the workpiece, and a strong wind that blows against the workpiece. an air blowing means for blowing off moisture adhering to the workpiece; and the air blowing means. Equipped with a heater that heats the workpiece that has passed through the means and dries and removes residual moisture. It is something that has been learned.

[0008]

[Effect]

In the drying device of the wet processing equipment of this invention, during the wet processing operation by the processing means, the drying device When removing the water that has been applied to the workpiece, first remove the water from the workpiece using a draining roller. After draining most of the water, it is then heated by a strong wind blown from the blowing means.

[0017] On the sub-conveyor device 15 at the left end of the table 3, there is a conveyor that is a component of the drying device. A wind nozzle 29 is provided, and a plurality of heaters 31 forming a component of the drying device are provided. They are arranged horizontally in the front-back direction so as to face each other vertically with the sub-conveyor device 15 in between. The workpiece being conveyed on the sub-conveyor device 15 is first By blowing air, the moisture on the workpiece is blown away, and the heat The workpiece is heated by a heater 31 to dry and remove any remaining moisture. .

[0018] A bucket 33 is installed at the bottom of the table 3 to catch water over almost the entire surface. In addition, a water tank 35 is installed at the lower left of the table 3, and a bucket The water accumulated in the tank 33 is drained into this water tank 35. water tank At 35, there is a filter to filter out deburring debris and fine powder from the water drained here. A passing paper 37 is provided. The water stored in the water tank 35 is then The water is supplied to the deburring work section by the pipe 21 through the water pipes 19a to 19c. Ru.

[0019] The structure of the pinch rollers 9a, 9b is shown in detail in FIGS. 4 to 6, and A roller is fixed to the frame 1 and arranged to straddle the deburring wheel 5 on the left and right. The deburring wheel 5 is placed horizontally in the front and back direction at each lower end position of the left and right sides of the support 39. Pinch rollers 9a and 9b of the same length are installed.

[0020] A sprocket that rotates together with the pinch rollers 9a and 9b is provided at the rear end of the pinch rollers 9a and 9b. 41a and 41b are provided coaxially. In addition, the left and right sides of the roller support 39 The pinch rollers 9a and 9b are placed at positions surrounding each upper deburring wheel 5. Auxiliary sprocket that can rotate freely to correspond to sprockets 41a and 41b 43a and 43b are attached. And these four sprockets 4 A chain 45 is wound around 1a, 41b, 43a, and 43b, and the left and right One of the pinch rollers 9a rotates due to frictional contact with the conveyor device 11. By doing so, the four sprockets 41a, 41b, 43a and 43b all rotate in the same direction, and as a result, the other pinch roller 9b can also be driven to rotate in the same direction.

[0021] Therefore, a thick workpiece is now being conveyed on the conveyor device 11 from the right side. When it comes between the pinch roller 9a on the right side and the conveyor device 11, this The rotation of the pinch roller 9a is temporarily stopped in order to separate from the conveyor device 11. However, the left pinch roller 9b is maintained in contact with the conveyor device 11. The pinch roller 9a on the right side is also rotated via the chain 45. The rolling will continue, and the workpiece must be held in the direction of the deburring wheel 5. You will be able to move it around. For this purpose, the left and right pins are Since the milling rollers 9a and 9b rotate independently, the workpiece with a large thickness is placed on the right side. This pinch roller 9 enters between the pinch roller 9a and the conveyor device 11. The rotation of a stops, the work stops here, and the material gets jammed. It will be possible to prevent this from occurring.

[0022] The blower nozzle 29, which constitutes a component of the drying device, is equipped with a tile, as shown in detail in FIGS. Installed in the front-rear direction above the sub-conveyor device 15 on the left side of the conveyor belt 3. The sub-conveyor is Air is blown onto the air device 15. And this blow nozzle 29 A duct 49 is connected to the duct 49, and the other end of the duct 49 is connected to a blower 51. ing. The blower 51 is attached to a blower frame 53 and is movable. It looks like this. Therefore, the air sent from the blower 51 through the duct 49 is sprayed from the air outlet 47 of the air nozzle 29 onto the workpieces on the sub-conveyor device 15. The moisture adhering to the workpiece can be blown off by blowing the workpiece. this The spraying speed is preferably about 30 m/sec.

[0023] Furthermore, as shown in FIG. 9, the belt is rotated by a conveyor drive motor 13. The draining rollers 27b, 27c and the blower nozzles 29 now face each other vertically. A drying device is constituted by a heater 31 arranged so as to face the wet deburring A drying process for the workpiece after deburring the device is performed here.

[0024] In other words, the draining rollers 27b and 27c are in pressure contact with each other, and there is no water between them. The moisture attached to the workpiece is squeezed out by passing it through the workpiece. Ru. Then, strong wind blows from the blow nozzle 29 onto the drained workpiece. The water is further blown off and removed. and, The workpiece from which water has been sufficiently removed is passed between the heaters 31 by the sub-conveyor 15. The remaining water is then evaporated and removed. And these The water removed during the draining and drying process is carried out in a bucket 33 below the table 3. The water is collected in a water tank.

[0025] Next, the operation of the wet deburring device having the above configuration will be explained.

[0026] The plate workpiece that has been pressed is fed to the right end of the table 3. The conveyor device 11 transports the material over the table 3 toward the deburring wheel 5 . The deburring wheel 5 is rotated at high speed by a drive motor 7 and reciprocated in the front and rear direction. The deburring machine continuously performs deburring work by touching the conveyed workpiece. At this time, Pinch rollers 9a and 9b hold the workpiece on both sides of the deburring wheel 5, and prevents the metal from dancing during deburring work.

[0027] During the deburring work, the pump 21 removes the tube 23 and the water pipes 19a, 1. Water from the water tank 35 is applied to the vicinity of the deburring work area via pipe 9b, and the deburring work area is The deburring work is performed in a wet state, and due to contact friction between the deburring wheel 5 and the workpiece. It can sufficiently cool down the heat generated by friction, and also reduce the amount of burr and debris removed from the workpiece. Fine dust can be taken into the water and not dispersed into the air, protecting the environment. This means that deburring work can be done without causing any deterioration.

[0028] The workpiece that has been deburred is further transported to the left by the conveyor device 11. When the workpiece is fed and passes under the brush roller 25, the work surface is removed by the brush roller 25. Deburring debris and fine powder adhering to the surface along with moisture are swept away, and then Then, the remaining deburring debris and fine dust are removed by the water sprayed from the water pipe 19c. The water is washed away and conveyed to the draining rollers 27a to 27c that constitute the drying device. Ru.

[0029] In the portion of the draining rollers 27a to 27c, the draining rollers 27a to 27c work. The water is drained by rotating while pressing against the front and back of the pipe. And the draining roller 27 After a to 27c, when the air is sent under the air nozzle 29, the air nozzle 29 or The moisture on the workpiece is blown away by the strong wind blown from the workpiece, and the sub-conveyor equipment 15 to the position of the heater 31, it is dried by the heat of the heater 31. After that, it is carried out from the left end of the table 3.

[0030] On the other hand, water supplied onto the workpiece from the water pipes 19a to 19c and the draining roller 27 The water drained from parts a to 27c is blown away by the wind from the blower nozzle 29. All of the water that has been removed is received by the bucket 33, and the water in this bucket 33 is is led to the water tank 35 from the bottom, and deburred debris and fine dust are removed by a filter paper 37. After being filtered, it is collected in the water tank 35. Then, it is collected in this water tank 35. The water is supplied to the water pipes 19a to 19c by the pump 21 and reused. Ru.

[0031] In this way, in this example, deburring is performed wet, and the deburring work is completed. In order to remove moisture from the finished work using a drying device and dry it, first The water is removed by the drain roller, and the air is blown out with strong force from the blower nozzle. Blow away any moisture on the workpiece, and then remove any remaining moisture with a heater. It is possible to heat and dry the workpiece and send out the workpiece with the moisture sufficiently dried and removed. can.

[0032] Note that this invention is not limited to the above embodiment, and wet machining is also possible. There are no particular limitations as long as the equipment is suitable for wet-processing workpieces. Thus, the drying apparatus of the above embodiment can be widely used.

[0033]

[Effect of the idea]

As described above, according to this invention, first, for a workpiece that has been wet-processed, Most of the moisture is removed by a drain roller, and then the workpiece is transferred to the workpiece by a blower. By blowing a strong wind, the moisture is blown away, and any remaining moisture is removed. Since the moisture is removed by drying with a heater, hot air is not used like in the past. It is possible to give stronger force to the wind than when blowing on the workpiece, Most of the moisture can be removed by this blowing means, and only a small amount is removed by the heater that follows. Only the remaining moisture needs to be dried, leaving no stains on the workpiece. , moisture can be removed reliably.
