Abstract

(57) [Summary] [Purpose] To obtain a separator for resin products and sprue runners that can separate a wide range of products without the need for human labor. [Structure] When the product / sprue runner is dropped onto the upper surface of the vibration plate 15 of the mesh belt 2, the product and the sprue runner no longer overlap with each other, and due to the difference in shape,
The product slides down without falling onto the surface of the mesh belt 2 and falls below the lower end of the mesh belt 2, and the sprue runner easily gets caught on the surface of the mesh belt 2, so as the mesh belt 2 moves upward. It is configured so that it is transferred upward and falls from the upper end to the outside, so that the two are separated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a separation device that automatically separates a resin-molded product from a sprue runner.

[0002]

[Prior art]

 Conventionally, it is possible to take out the product with various chucks and drop the sprue runners to the outside when removing the product from the machine in a large molding machine. In many cases, it is difficult to automatically separate the product from the sprue runner when it is taken out, and it is not possible to carry out the separation in response to the production of many types of products. It is done by relying on human resources.

[0003]

[Problems to be solved by the device]

 By the way, when the separation work is manually performed, the molding time by the molding machine is longer than the time required for the separation work, and a waiting time occurs during that time, resulting in a loss time.

The present invention is intended to obtain a product / sprue runner separator which can perform separation corresponding to a wide range of products without requiring human labor.

[0005]

[Means for Solving the Problems]

 The present invention has the following configuration in order to solve the above problems. A mesh belt is rotatably mounted between pulleys supported on both ends of the frame, and the frame is supported on one side so that the moving side of the mesh belt is higher, and the other side is supported on the lower side. In addition to providing a lifting mechanism to adjust the tilt angle of the mesh belt, it also vibrates vertically on the mesh belt that moves through round bars that are arranged at a right angle on the lower surface of the upper center of the upper mesh belt. A product sprue runner separator configured to supply a product sprue runner to be separated to the central portion of the mesh belt by providing a vibrating device for providing the product sprue runner.

【Example】

 1 is a side view showing a product sprue runner separator according to the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a side view of FIG.

As shown in FIG. 1, pulleys 3 and 4 around which the mesh belt 2 is stretched are provided at the left and right ends of the horizontally long frame body 1. The left pulley 3 has a tension adjustment device for the mesh belt 2. 5 is provided, and the right pulley 4 is configured to be driven by a motor 6 provided in the frame 1 via a belt 7.

As shown in the figure, on the pulley 3 side, the lower surface of the frame 1 is pivotally supported by a support shaft 10 on a support column 9 from a mounting base 8 with a tilt angle adjustable, and fixed by a peripheral groove and a fixing device 11 using a screw. Further, the lower surface of the pulley 4 side is supported by the jack 12 mounted on the mounting base 8 via the connecting rod 13, and the frame body 1 is supported by the jack 12 ascending through the connecting rod 13. As shown by an imaginary line, it can be tilted with the support shaft 10 as a fulcrum, and can be fixed in the tilted state by the fixing device 11. The pulley 4 drives the mesh belt 2 so that the surface of the mesh belt 2 is directed in a higher direction (arrow direction in FIG. 2).

Further, a vibration generator 14 is provided inside the frame 1, and a vibration plate 15 provided on the upper surface of the vibration generator 14 has a round bar of about 5 mmφ at both ends perpendicular to the traveling direction of the mesh belt 2. 16 and 16 are provided so that the moving mesh belt 2 comes into contact with the mesh belt 2 in a state of being slightly lifted, and the vibration from the vibration generator 14 is applied to the mesh belt 2 from the back surface.

A side wall plate 17 is provided at left and right positions in the moving direction of the mesh belt 2 of the frame body 1 in order to prevent the product or the like supplied on the mesh belt for separation from falling due to vibration. The rivet guide 18 is provided on the mesh belt 2 as shown in FIG. 3, and the guide grooves 19 are formed on the pulleys 3 and 4 in correspondence with the rivet guide 18. You will be guided correctly without moving sideways.

Adjustment of the tilt angle of the frame body 1 supporting the mesh belt 2, the speed of the mesh belt 2, the frequency of the vibration generator 14, the tension of the mesh belt 2, the mesh belt It can be appropriately adjusted according to the size, shape, etc. of the object to be separated, such as replacement of item 2.

When separating the product and the sprue runner, the product and the sprue runner discharged from the molding machine are discharged in a state in which the product and the sprue runner are mixed in a loose manner at the take-out port. When dropped onto the upper surface of the vibrating plate 15 of the belt, the product slips downward without catching the surface of the mesh belt 2 due to the difference in shape between the product and the sprue runner, and falls below the lower end of the mesh belt 2. Since the sprue runner is easily caught on the surface of the mesh belt 2, the sprue runner is moved upward as the mesh belt 2 moves upward, and falls from the upper end to the outside, so that the two are separated. .

Since the frictional force between the product and the surface of the mesh belt 2 also poses a problem during separation, it is advisable to apply Teflon processing to the surface of the mesh belt. This also improves the heat resistance of the high-temperature parts taken out from the molding machine.

Further, the mesh size of the mesh belt and the inclination angle are also adjusted so as to be in an optimum state for product separation. It should be noted that the vibration of the mesh belt by the diaphragm 15 is used as a means for releasing the overlap in order to prevent the products and the sprue runners from overlapping and supporting the separation action. In addition, the round bar 16 attached to the vibrating plate is pushed up the part caught by the round bar 16 when the product is transferred upward while the product is caught on the belt mesh. To work.

The product / sprue-runner separator according to the present invention is configured as described above, and includes a mesh size of the mesh belt 2, an inclination angle, a moving speed, and a vibration generator corresponding to the articles to be separated. By appropriately changing the applied frequency of, it can be efficiently used for most product separations.

It should be noted that the mesh belt drive, the inclination angle control mechanism, the vibration imparting device, etc. may use other appropriate means.

[0017]

[Effect of device]

 As described above, according to the present invention, the resin molded product and the sprue runner can be separated with a device having a simple structure such as a belt conveyor, and the mesh size of the mesh belt 2, the friction coefficient, and the inclination angle. , The moving speed and the vibration frequency given by the vibration generator can be adjusted appropriately according to the product to be separated, so that the separation work can be performed efficiently, and it is necessary to manually perform the separation work as in the past. Disappears. Further, it can be easily installed and moved.

Further, in the molding machine, the molding time is longer than the separation time, and in the case of manual work, the waiting time of the hand is generated and the efficiency is low. On the other hand, according to the separation device of the present invention, Since no labor is required for separation, continuous operation at night is possible.
