[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating device for automatically separating a product after resin molding from a sprue runner.

[0002]

2. Description of the Related Art Conventionally, in a large molding machine, when removing a product from the machine, the product is taken out with various chucks.
Although it is possible to drop the sprue runner separately, it is difficult for small molding machines to automatically separate the sprue runner from the sprue runner when removing the product after resin molding. In addition, separation cannot be performed in response to the production of various types of products, and such separation work is performed manually.

[0003]

However, when the separating operation is performed manually, the molding time by the molding machine is longer than the time required for the separating operation, so that a waiting time occurs during the operation, resulting in a loss time.

SUMMARY OF THE INVENTION The present invention aims to obtain a product / sprue runner separator which can be separated for a wide range of products without requiring any manual operation.

[0005]

Means for Solving the Problems The present invention has the following structure to solve the above-mentioned problems. A mesh belt is rotatably mounted between pulleys supported on both ends of the frame body, and the frame body is supported on one side below so that the moving side of the mesh belt surface is higher, and a lifting mechanism is provided on the other lower side. It is possible to adjust the inclination angle of the mesh belt and to apply vertical vibration to the mesh belt moving through round bars arranged at right angles at intervals in the direction of travel of the mesh belt on the lower surface of the center of the upper mesh belt. A product sprue runner separator provided with a vibration device and configured to supply a product sprue runner to be separated to the central portion of the mesh belt.

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 are provided at the left and right ends of the horizontally long frame 1 so that a mesh belt 2 is wound around the left and right pulleys 3. The right pulley 4 is configured to be driven via a belt 7 by a motor 6 provided in the frame 1.

As shown in the figure, the lower surface of the frame 1 is supported on a column 9 from a mounting base 8 by a support shaft 10 on a pulley 3 side so that the inclination angle can be adjusted, and is fixed by a fixing device 11 using peripheral grooves and screws. The lower surface on the pulley 4 side is supported by a jack 12 attached to the mounting base 8 via a connecting rod 13, and when the jack 12 rises, the frame 1 is connected via the connecting rod 13.
Can be tilted with the support shaft 10 as a fulcrum as shown by a virtual line, and can be fixed to the tilted state by the fixing device 11. The pulley 4 drives the mesh belt 2 so that its surface faces in a high direction (the direction of the arrow in FIG. 2).

A vibration generator 14 is provided inside the frame 1. A vibrating plate 15 provided on the upper surface of the vibration generator 14 has round rods of about 5 mmφ at both ends perpendicular to the traveling direction of the mesh belt 2. 16 and 16, the moving mesh belt 2 comes in contact with the mesh belt 2 while being slightly lifted,
More vibration is applied to the mesh belt 2 from the back side.

Note that side wall plates 17 are provided on the left and right positions of the frame 1 in the traveling direction of the mesh belt 2 in order to prevent a product or the like supplied on the mesh belt for separation from falling outside due to vibration. The mesh belt 2 is provided
As shown in FIG. 3, a rivet guide 18 is provided, and a guide groove 19 is formed in the pulleys 3 and 4 corresponding to the rivet guide 18, so that the mesh belt 2 is correctly guided without moving laterally.

The inclination angle of the frame 1 supporting the mesh belt 2 is adjusted, the speed of the mesh belt 2 is adjusted,
The frequency of the vibration generator 14, the tension of the mesh belt 2, the replacement of the mesh belt 2, and the like can be appropriately adjusted according to the size and shape of the separation target.

When separating the product and the sprue runner, the product and the sprue runner discharged from the molding machine are:
Since the product and the sprue runner are discharged in a state of being mixed separately at the outlet, when these are dropped on the upper surface of the diaphragm 15 of the mesh belt, the product is meshed due to a difference in shape between the product and the sprue runner. The sprue runner slides down without falling on the surface of the belt 2 and falls below the lower end of the mesh belt 2, and the sprue runner is easily caught on the surface of the mesh belt 2. As a result, it falls from the upper end to the outside, and both are separated.

Since the frictional force between the product and the surface of the mesh belt 2 also causes a problem in separation, the surface of the mesh belt may be subjected to Teflon processing. By doing so, the heat resistance of the high-temperature component taken out of the molding machine is also improved.

Further, the size and the inclination angle of the mesh of the mesh belt are also adjusted so as to be in an optimum state for separating products. Vibration of the mesh belt by the vibration plate 15 is used as a means for releasing the overlap in order to prevent the product and the sprue runner from overlapping and supporting the separating action. In addition, the round bar 16 attached to the diaphragm acts as an aid when the product is transported upward with the product hooked on the belt mesh, the portion caught by the round bar 16 is pushed up, the hook is released, and the product slides down. I do.

The product / sprue runner separator according to the present invention is configured as described above, and the mesh size, inclination angle,
By appropriately changing the moving speed and the frequency applied from the vibration generator, it can be efficiently used for most product separation.

The mesh belt drive, the tilt angle control mechanism, and the vibration imparting device may use other appropriate means.

[0017]

As described above, according to the present invention, the separation between the resin molded product and the sprue runner is performed by a device having a simple configuration such as a belt conveyor, and the mesh size of the mesh belt 2 is reduced. Friction coefficient, inclination angle, moving speed,
By appropriately changing the applied frequency from the vibration generating device, it is possible to appropriately adjust and respond to the product to be separated, so that the separating operation can be performed efficiently, and it is not necessary to perform the operation manually as in the conventional case. Furthermore, installation and movement can be easily performed.

Further, in the molding machine, the molding time is longer than the separation time, and when it is performed manually, a waiting time is required and the efficiency is low. Since no manual operation is required, continuous operation at night is also possible.
