Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for taking out a workpiece, and in particular, a device for reversing and taking out a fired body (hereinafter referred to as a workpiece) from a container in a firing process in the manufacture of ferrite magnets. It is related to.

[Conventional technology]

In the firing process? 1 [Containers containing several stacked and irregularly arranged workpieces are continuously processed in a firing furnace. Since the container is used repeatedly during the firing process, the workpiece must be removed from the container after the firing process is completed. This removal work was previously done by hand.
Recently, in order to automate the process, attempts have been made to use mechanical hands, vacuum suction hands, and magnetic suction hands in visual robots.

[Problem that the invention seeks to solve]

However, since it is necessary to deal with a wide variety of target workpieces with different dimensions and shapes, when a robot with vision is used, the following problems arise.

1. Calculation time is required to determine the position of the workpiece in the container, which takes processing time.

2. Since there is a limit to the ability of mechanical hands to handle a wide variety of products, it takes time to set up and change hands depending on the product.

3. Regarding the vacuum suction hand, an air gap occurs between the hand suction surface and the workpiece due to the size and shape of the workpiece, making suction impossible.

4. Regarding the magnetic attraction hand, since the workpiece is magnetized, demagnetization processing is required after taking out the workpiece, resulting in high cost.

An object of the present invention is to provide a workpiece unloading device that does not require setup changes for a wide variety of workpieces and has a short processing time.

[Means for solving problems]

The present invention takes the following technical measures in order to eliminate the drawbacks of the prior art described above. That is, it has a container positioning table, a work holding device that presses a work toward the table, which is disposed at a position facing the table, and a flexible bell 1- provided between the table and the work holding device. The workpiece retrieval device is attached to a reversing device whose rotational axis is in the horizontal direction, so that the container can be inverted and a large number of workpieces packed in the container can be moved into the container at once without spilling the workpieces. The purpose is to take out the workpiece. Incidentally, if the rubber tubes and the dispensing plates 1- are arranged in multiple rows alternately on the workpiece holding surface of the workpiece holding device, the rubber tubes will absorb variations in the height of the workpieces in the container, making it possible to hold the workpieces securely. Furthermore, since the unloading plate keeps the lower surface of the belt at a constant level, stable unloading of the workpiece is possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cross-sectional view of the overall configuration.

Shafts 6 and 7, which have bearings 4 and 5 disposed on the same rotating shaft and are fixed to both ends of a casing 8, are attached to the pedestal 1. Further, a rotary actuator 2 fixedly attached to the pedestal 1 is coupled to a shaft 6, making the casing 8 rotatable.

The workpiece unloading surface L, the workpiece holding surface of the holding device 15, and the container positioning table 21 are arranged parallel to the rotation axis of the casing 8.

There is a holding device on the reference surface of casing 8! 15 has a hole through which it can pass, and the presser device is arranged so that when the cylinder 9 is retracted, the presser surface and the reference surface are on the same plane,
When the cylinder 9 is extended, it passes through the casing 8 and can move toward the table 21 located at the opposite position. A stopper 22.51 is provided on the table 21 so that the presser device 15 can enter inside the container 25 and press the workpiece.
A positioning device consisting of a cylinder 27 and the like is attached. The table 21 also includes a container catch 23.2.
4 is fixed. (According to this embodiment, by this catch.

Even if the bottom of the container is dented due to use, the container can be positioned in a stable manner. In the absence of a catch, the container was sometimes positioned in an inclined position. ) The container 21 has a cylinder 19.20 and a guide rod 28.
．． 29 etc., it is possible to move in the direction of the opposing presser device 15. According to this embodiment, by bringing the rim of the container close to the workpiece delivery reference surface, unstable workpieces falling from the workpiece holding device during removal are guided by the container rim and prevented from falling. If the work is stable and does not fall, the movement mechanism for the table 21 may be omitted.

The dispensing belt 18 is disposed between the presser foot [15] and the table 21, and is connected to the rolls 3 attached to both ends of the dispensing reference surface.
9.38, and both ends of the belt 18 are fixed to separate winding drums. The winding drum is supported by bearings 40 and 41 attached to the casing 8, and is rotated in forward and reverse directions by a motor 54 via gears 34 and 35 to perform winding. The other winding drum also has a similar mechanism. According to this embodiment, since both ends of the belt [8 are fixed to the winding drum, stable delivery is possible without meandering even if a belt or cloth that can be deformed according to the unevenness of the work is used. Further, the guide frame 16,1 has a guide plate 42 attached to the belt parallel to the dispensing direction.
7 to ensure stable dispensing without belt wrinkles.

FIG. 6 shows one embodiment of the holding device. Rectangular parallelepiped pillars are arranged at a predetermined pitch on a holding plate 47 using spacers, and a rubber tube 45 is placed on the holding surface side of the pillars.

A rubber tube holding plate 46 is fixed on the side of the column while passing through the rubber tube. A dispensing plate 50 is disposed between the rubber tubes, a spring 48 is disposed between the dispensing plate 50 and the holding plate 47, and the bolt 48 is passed through the spring through the hole in the holding plate 47 and attached to the dispensing plate 50. Secure with screws. The upper surface of the dispensing plate is set on the same belt as the dispensing surface of the casing, and the rubber tube is set lower than the dispensing reference surface.

According to this embodiment, when discharging a workpiece, the belt 18 places the workpiece thereon, and can perform a good dispensing while sliding on the discharging plate, and when holding the workpiece, the cylinder 9, which generates a force greater than the force of the spring 49, is used. The payout plate sinks according to the deformation of the rubber tube, so it is possible to handle workpieces of different heights inside the container, and even when the container is turned over, the workpieces are held down by the rubber tube and will not shift or fall. . In addition, since the delivery belt 18 comes into contact with the workpiece when holding the workpiece, it prevents the occurrence of scratches on the workpiece and
Use a flexible material to absorb variations in workpiece height.

Next, the operation of this invention will be explained.
