However, the conventional molded product take-out apparatus cannot meet this requirement. That is, the mold surface of the mold to which a plurality of molded products are attached is a surface vertical to the installation surface of the mold, and when the molded product is taken out from such a vertical mold surface, the chuck member is used. , The product holding surface must stand vertically so that it faces the mold surface. Then, when the chuck member moves to the product discharge position in this state and the holding of the molded product is released, as shown in FIG. 8, each of the plurality of molded products held is naturally dropped as it is, These cannot be sorted and stored for each cavity.

The present invention has been made based on the above circumstances, and its object is to sort a plurality of molded products attached to a vertical mold surface of a mold into cavities. An object of the present invention is to provide a molded product takeout device that can be stored as a package.

[0007]

The molded product take-out device of the present invention comprises a plurality of moldings attached to the vertical mold surface of one mold of the resin molding machine after the molding process by the resin molding machine is completed.

[0009]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an explanatory perspective view showing a time-dependent operation of a chuck member in a molded product take-out apparatus of the present invention. The chuck member 60 holding the molded product at the "product take-out position 10A" moves to the "product discharge position 10D" through the "standby position 10B", the "runner discharge position 10C". In addition, 10 is a base frame, 15 is a running path fixed to the basic frame 10, 20 is a runner running on the running path 15, 30 is a sleeve fixed to the runner 20, and 40 is a sleeve 30. A head 50 rotatably attached to the head 40 is rotatably attached to the head 40 and a support base for fixedly supporting the chuck member 60. M is a drive motor for moving the runner 20.

In the "product take-out position 10A", the chuck member 60 is vertically erected so that the product holding surface 61 thereof faces the mold surface (not shown) of the mold.

Next, the chuck member 60 moves to the "standby position 10B" which does not hinder the opening and closing of the mold while maintaining this posture. When the chuck member 60 has not reached the "standby position 10B", the opened mold cannot be closed.
From the viewpoint of efficiency, the movement from “A” to the “standby position 10B” is performed at high speed, and the movement from “standby position 10B” to “product discharge position 10D” is performed at low speed. By moving the chuck member 60 at a low speed, the chuck member 6
It is possible to surely perform the position control of 0, and to prevent a molded product from dropping while moving. As a means for switching the chuck member 60 moving at a high speed to a low speed, a speed control means using a light beam, a micro switch, or the like can be mentioned, but the details will be described later.

Next, the chuck member 60 moves to the "runner discharge position 10C". Then, "standby position 10
While moving from "B" to "Runner discharge position 10C",
The chuck member 60 is rotated 90 degrees around the horizontal axis α of the sleeve 30 and is rotated 90 degrees around the orthogonal axis β orthogonal to the horizontal axis α, and the product holding surface 61 thereof faces downward. It becomes a state.

At "runner discharge position 10C",
The runner connecting multiple molded products is discharged.
Further, in this "runner discharge position 10C", defective products among molded products can be discharged at the same time. The defective product can be detected by a sensor (not shown) provided at the “product take-out position 10A”.

Next, the chuck member 60 moves to the "product discharge position 10D" while maintaining the state in which the product holding surface 61 faces downward, and after reaching the "product discharge position 10D", of the molded product. Release the hold. As a result, each of the held molded products spontaneously falls while maintaining the mutual positional relationship, and is sorted into cavities into storage containers (not shown) that are divided according to the respective fall positions. Will be stored.

<Running of Traveling Element> The chuck member 60, together with the traveling element 20 which is driven by the driving force from the drive motor M, moves from the “product take-out position 10A” to the “product discharging position 10
Move to "D". Examples of means for causing the runner 20 to travel include means including a cross slide mechanism (see Japanese Patent Application No. 3-78341).
According to such means, the movement of the chuck member 60 between the “product take-out position 10A” and the “product take-out position 10D” and the approach / retract operation of the mold at the “product take-out position 10A”. Is preferable because it can be performed with high accuracy.

<Rotating Mechanism Around Horizontal Axis α> Head 4
0 is from "standby position 10B" to "runner discharge position 10"
While moving to “C”, it rotates 90 degrees about the horizontal axis α of the sleeve 30. FIG. 2 is an explanatory diagram showing a rotating mechanism of the head 40. In the figure, 41 is a rotating shaft of the head 40, 42 is a large diameter gear fixed to the rotating shaft 41, 43 is a small diameter gear meshing with the gear 42, and 44 is a rotating shaft of the small diameter gear 43. The rotating shaft 41 and the rotating shaft 44 are attached to the runner 20 to which the sleeve 30 is fixed via bearings, respectively, and the head 40, the large diameter gear 42, and the small diameter gear 43.
Moves in the direction indicated by the arrow together with the runner 20. 1
A rack 6 is attached to the base frame 10 so as to mesh with the small diameter gear 43. The mounting position of the rack 16 on the base frame 10 can be arbitrarily changed. When the small diameter gear 43 that moves together with the runner 20 meshes with the rack 16 and rotates, the large diameter gear 42 that meshes with the small diameter gear 43 rotates. This allows the head 4
0 rotates about the horizontal axis α of the sleeve 30. Here, the number of teeth of the rack 16 is 1/4 of the number of teeth of the large diameter gear 42.
Therefore, the rotation angle of the head 40 is 9
It will be 0 degrees.

<Locking Mechanism of Large Diameter Gear 42> The above rotating mechanism regulates the rotation of the head rotated 90 degrees about the horizontal axis α of the sleeve in that state. FIG. 3 is an explanatory diagram showing a lock mechanism of the large diameter gear 42 that rotates together with the head 40. In the figure, 45 is a large diameter gear 4
2 is a first regulating member receiver attached to the inner surface of
Reference numeral 6 denotes a second restricting member receiver mounted at a position rotated by 90 degrees from the first restricting member receiver 45. Reference numeral 70 denotes a restriction member that is attached to a sleeve (not shown) and that is displaced along the horizontal axis α. The tip 70A of the regulation member 70
Is the first restriction member receiver 45 or the second restriction member receiver 46.
The rotation of the large-diameter gear 42 is restricted by fitting it to. Reference numeral 17 is a cam member fixed to a specific position with respect to the rack 16, and 71 is a follower member that follows the cam surface of the cam member 17. The follower member 71 is fixed to the restricting member 70, and therefore the restricting member 70 is displaced through the follower member 71.

FIG. 4 shows a large-diameter gear 42 formed by the regulating member 70.
FIG. 3 is a schematic view of the lock mechanism of FIG. FIG. 6A shows a stage in which the small-diameter gear 43 has not reached the rack mounting position.
The front end 70A of No. 0 is fitted into the first restricting member receiver 45, and the rotation of the large diameter gear 42 is restricted. FIG. 6B shows a stage in which the small diameter gear 43 meshes with the rack. At this stage, the driven joint member 71 follows the cam surface (convex surface) of the cam member 17 and is separated from the large diameter gear 42. The restriction member 70 moves away from the first restriction member receiver 45, and the large diameter gear 42 can rotate.
FIG. 6C shows the stage where the small diameter gear 43 has passed the rack mounting position. At this stage, the driven node member 7
1 passes through the cam surface of the cam member 17, and the regulating member 7
The front end 70A of 0 is fitted into the second restricting member receiver 46, and the rotation of the large diameter gear 42 is restricted again.

<Rotating Mechanism Around Orthogonal Axis β> In the present invention, the chuck member is rotated 90 degrees about the horizontal axis α of the sleeve and 90 degrees about the orthogonal axis β. That is, the support base to which the chuck member is attached rotates 90 degrees with respect to the head. In this embodiment, the rotation about the orthogonal axis β (the rotation of the support base with respect to the head) is performed in conjunction with the rotation about the horizontal axis α of the sleeve (the rotation of the head with respect to the sleeve). FIG. 5 is an explanatory diagram showing a mechanism in which the sleeve is rotated about the orthogonal axis β along with the rotation about the horizontal axis α. In the figure, 35 is a bevel gear fixed to the sleeve 30, and 55 is a bevel gear that meshes with the bevel gear 35. The bevel gear 55 has the same diameter as the bevel gear 35, and is fixed to the rotating shaft 51 of the support base 50. When the runner (not shown) moves in the depth direction of the paper surface and the small diameter gear 43 meshes with the rack 16, the small diameter gear 43 and the large diameter gear 42 rotate. When the large diameter gear 42 rotates, the bevel gear 55 rotates in a direction in which the support base 50 tilts in the depth direction of the paper surface. Since the bevel gear 35 and the bevel gear 55 have the same diameter, the large-diameter gear 42 is
When the support base 50 is rotated by 0 degrees and stopped, the support base 50 is also rotated by 90 degrees (tilted) and stopped.

<Vehicle Speed Control Means> Next, a control means for switching the chuck member moving at a high speed to a low speed will be described. FIG. 6 is a schematic view of the speed control means of the runner as viewed from above the device. In the figure, 75 is a light beam generating means, and 76 is a light receiving part for receiving the light beam from the light beam generating means 75. At the stage where the small-diameter gear 43 has not reached the rack mounting position ((a) in the figure), the light beam from the light beam generating means 75 is received by the light receiving section 76. At this stage, the runner moves at high speed. Running. When the small diameter gear 43 meshes with the rack ((B) in the figure), the driven joint member 71 follows the cam surface of the cam member 17 and moves in a direction away from the large diameter gear 42. At this time, the light beam from the light beam generating means 75 is shielded by the driven node member 71, and the light receiving portion 76.
Does not reach When the light to the light receiving unit 76 is blocked, the detection signal is sent to the speed control unit 77, and the speed control unit 77 receiving this detection signal sends a deceleration signal to the drive motor M, whereby the drive motor M slows down.

The molded product take-out device of this embodiment has the following effects. (1) With the "rotation mechanism having the horizontal axis α as the axis" and the "rotation mechanism having the orthogonal axis β as the axis", the chuck member 60 is
The product holding surface 61 surely faces downward.
Since these rotation operations are performed in conjunction with the traveling of the traveling element 20, it is not necessary to separately provide a motor for rotation, and space efficiency is excellent. (2) The "large-diameter gear lock mechanism" restricts further rotation of the head rotated 90 degrees around the horizontal axis α of the sleeve. Therefore, the chuck member 60 can move to the "product discharge position 10D" while maintaining the state in which the product holding surface 61 faces downward. (3) The chuck member 60 is moved from the "standby position 10B" to the "product discharge position 10D" by the "runner speed control means".
When moving to, the moving speed is switched to a low speed. Therefore, the position control of the chuck member 60 can be surely performed, and a fall accident of the molded product during movement can be prevented. (4) As a result of the above series of operations, the “product discharge position 10
The chuck member 60 in “D” has its product holding surface 61.
Is facing downwards. Therefore, each molded product can be sorted and stored for each cavity.

[0022]
