Abstract

(57) [Summary] [Purpose] To enable smooth deburring work without material clogging even on thick workpieces. [Structure] When a workpiece with a large thickness is sent upstream on a conveyor, the sprockets are connected by a chain between the pinch rollers on both sides of the deburring wheel. Therefore, even if the upstream pinch roller attempts to stop, the downstream pinch roller contacts the conveyor device and continues to rotate. As a result, the rotational force of the downstream pinch roller is transmitted to the upstream pinch roller via the chain and sprocket, forcing it to continue rotating.
This allows the workpiece to be held in the mouth, allowing smooth deburring work without material clogging.

[Problem that the idea aims to solve]

However, with such conventional deburring equipment, the workpiece is first pinched on the upstream side. The deburring wheel is sent between the roller and the conveyor device. Especially since the pinch rollers on the upstream and downstream sides of the wheel can rotate independently of each other. When a thick workpiece is transported by a conveyor device, a pinch occurs on the upstream side. The rollers have stopped rotating and I am having trouble getting the workpiece under the pinch rollers smoothly. This prevents the workpiece from being fed under the deburring wheel. However, there was a problem in that the work could easily get jammed.

0004 This idea was created in view of these conventional problems, and it prevents work from clogging. To provide a deburring device that is less likely to occur and can perform deburring work smoothly. The purpose is to

[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 workpiece stops here, and material jams occur. Never.

[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 embodiment, the deburring operation is carried out by the deburring wheel. When doing so, the pinch rollers that hold the workpiece on both sides always rotate together. Because they are connected by sprockets and chains, thick workpieces are This could lead to a situation where the roller is fed into the pinch roller on the downstream side and stops rotating. However, the pinch roller on the downstream side is in contact with the conveyor device and continues to rotate. In addition, the upstream pinch roller is also forced to rotate via the sprocket and chain. This allows the workpiece to be smoothly fed to the deburring wheel side. It will be possible.

[0032] In addition, in the above embodiment, a chain is used to rotate the pinch rollers in conjunction with each other. In order to connect the roller support, two separate free-rotating sprockets are installed on the roller support. The structure was such that a chain was wrapped around the installation and deburring wheel. However, even if you try to connect the sprockets of the pinch roller directly with a chain, Positional relationship where the chain cannot be wrapped around the shaft end of the deburring wheel because it gets in the way This is because . Therefore, due to the structure of the mechanical device, both pinch rollers If you can connect the sprockets directly with a chain, they will still rotate together. It may be possible to do so.

[0033]

[Effect of the idea]

As described above, according to this invention, deburring work is performed using a deburring wheel. When pinch rollers hold the workpiece on both sides, the pinch rollers are rotated so that they always rotate together. Because they are connected by a sprocket and chain, thicker workpieces can be moved upstream. The situation was such that it was fed into the pinch roller on the side and stopped rotating. However, the pinch roller on the downstream side is in contact with the conveyor device and continues to rotate. The upstream pinch roller is also forced to continue rotating via the sprocket and chain. The workpiece can be smoothly fed to the deburring wheel. This eliminates material clogging and allows for smooth deburring of thick workpieces. can be done.
