In other words, in a plastic molding machine, the molded product can fall out of the mold and fall freely, so it is relatively easy to take it out, but it is necessary to do this reliably and to Full automation of the molding machine cannot be achieved unless alignment is made convenient for automatic packaging.

For this reason, various proposals have been made for the ejecting device for plastic molding machines. Alternatively, in order to shorten the take-out operation cycle, the molded product is automatically taken out by moving the flashing plate mechanically in conjunction with the movement of the movable guide plate. 36866
A number of proposals have been made, including the following:

However, when taking out the molded product automatically, conventional products are equipped with a gripping device using a robot or a chuck device using a suction cup, as seen in the public shaft of Japanese Patent Publication No. 53-9. If stacking is to be carried out, it becomes complicated, and especially in the case of a chuck device using a suction cup, a separate molded product stacking device is required.

[Means for Solving the Problems] Therefore, the present invention was created to solve the problems of the prior art. Specifically, the present invention was created to solve the problems of the prior art. a pallet that receives a container-shaped molded product; a transverse carriage that places the pallet and pulls it horizontally; an elevating carriage to which the pallet is transferred from the transverse carriage and that moves up and down; and the elevating carriage. The carriage at the upper boundary of about 1
An object of the present invention is to provide a molded product stacking device for a plastic molding machine, which is constituted by a molded product stacking device into which molded products are input after being turned 80 degrees and placed on a conveyor.

Hereinafter, the structure of the present invention will be explained in detail with reference to embodiments shown in the accompanying drawings.

First, the outline of this embodiment will be explained based on FIG. 1.

That is, the injection molding machine 1 injection molds molded products such as plastic barrels, plastic wash basins, lids and necks for plastic barrels, and containers such as baskets.
After molding, the molded product remains in the movable mold 4 attached to the side surface of the movable goo plate 3. 2 indicates a stationary mold, and the molded product is dropped from the movable mold 4 using an ejector turbine 5° or an air blower 6° (see Figure 2). It is guided by the described take-out device and turned 90 degrees and allowed to fall freely. That is, this take-out device is composed of a curved guide tube A, a funnel-shaped guide device B, and a receiving pallet C, and the curved guide tube A is inserted between the open molds 2.4.
The molded product remaining in the mold 4 is configured to be moved in an arc from above to cover the molded product before falling down, and
The funnel-shaped guide device B is provided directly below the downward opening to the curved guide tube, and furthermore, the packet c is provided below the funnel-shaped guide device B and can be pulled horizontally. . After covering the molded product onto the curved guide tube, the molded product is separated from the mold 4 by an ejector turbine 5'', an air blower 6'', etc., and the molded product that has fallen is released into the curved guide tube. The molded product is guided, reversed 90 degrees, and falls freely.The molded product that is falling is corrected in its falling position by a funnel-shaped guide device B.
It falls onto pallet C and places 11 on it. The pallet C is mounted on a pallet receiver 5, and the pallet receiver 5 is placed on a traversing carriage 6. When the traversing carriage 6 is pulled laterally, the pallet receiver 5 is inserted into the bifurcated portion at the tip of the swing arm 7 and held by the swing arm 7. Therefore, since the swing arm 7 is attached to the elevating carriage 8,

Next, these members and steps will be explained in more detail.

[About curved guide tube A]

In FIG. 2 and FIG. 3, which is a view taken in the direction of arrows 33 to S3, the illustrated device is a bent tube type molded product guide device mainly consisting of a bent guide tube A, and is installed on the die plate 3. has been done. When the molded product E is molded and the mold 2.4 is opened, the cylinder 14 on the slider 13 is actuated, and the bending guide tube A descends in an arc shape toward the mold 4 and the molded product E to cover the mold 4 and the molded product E. Next, the molded product E is dropped from the mold 4 using an ejector turbine of 5 degrees, an air blower of 6 degrees, etc., and the dropped molded product E is allowed to fall freely while being reversed by 90 degrees in the curved guide tube A.

The inner diameter of the curved guide tube is slightly larger than the outer shape of the molded product E, and the inner diameter of the curved guide tube is made slightly larger than the outer shape of the molded product E. Therefore, the knob 15 and thumbscrew 16 are loosened so that they can be easily removed from the pivot arm 17. In addition, the curved guide tube A is standardly a 90-degree elbow type in order to reduce the opening stroke of the mold 2.4, but it is used for flat molding such as lids for plastic barrels that easily change direction after falling. For product E, a 90 degree elbow type may be used.

Furthermore, in order to facilitate the replacement of the mold 2.4, the crank handle 18 is turned and the vertical feed screw 19 and guide bar 2 are removed.
0, and then turn the ratchet handle 21 to move the saddle 23 backward through the left and right feed screws 22, so that the entire body is moved backward from the front surface of the movable gouy plate 3. There is. Of course, at this time,
Remove the curved guide tube A.

Note that the bending guide tube A shown in FIGS. 4 and 5 is a special tool for flat molded products E such as bra barrel lids, but when this type of flat molded product E is dropped from the mold 4, When passing through the curved guide tube, it may turn 180 degrees and come out upside down. Therefore, from the vertical plane to the curved guide tube,
A plurality of thin cylinders 25 are arranged at a tilted position, the molded product E is stopped at this position, and then the rod 26 of the thin cylinder is depressed, and the molded product E remains as it is. , can fall freely and align in the same direction. Reference numeral 27 indicates an electromagnetic switching valve that operates the thin cylinder 25.

(Regarding the funnel-shaped guide device B) In FIGS. 3 and 6, the molded product E that exits the curved guide tube A and falls freely is provided with the funnel-shaped guide device B directly below it, so that the molded product E Even if the falling angle position of the drop is slightly shifted, it will be corrected so that it is horizontal at the fixed position.In other words,
tfIa dowel-shaped guide system r! The IB is composed of a funnel 28, and the funnel 28 is provided on a frame-shaped fixed block 30 assembled to both horizontal supports 29 of the take-out molding machine l, and the block 30 has slide guide rods assembled on both sides. A sliding block 32 that slides on the funnel 28 is provided, and a handle 33 that connects both blocks is provided on the sliding block 32, and by reciprocating the handle 33, the forward and backward position of the funnel 28 is adjusted. .

[About Palette C]

In FIG. 7 and FIG. 8, which is a view taken from arrows 37 to S7, the molded product E that has passed through the funnel-shaped guide device B, has been positioned and dropped, is placed in the ring-shaped pallet C that is waiting directly below it. Fall. The pallet C is mounted on a pallet receiver 5, and the pallet receiver 5 is placed on a traversing carriage 6. The traversing carriage 6 is traversed on the beam 48 by a currency drive. The end of the pallet receiver 5 that has been pulled horizontally is inserted into the space of the upper and lower bifurcated portions formed at the tip of the swing arm 7, and the inserted pallet receiver 5 is gripped and held by the swing arm 7. That is, the rods of a plurality of thin cylinders 35 provided on the lower surface of the swing arm 7 protrude and press the pallet receiver 5 against the lower surface of the bifurcated arm 7. During this pressing, if the pallet holder 5 deviates by one position relative to the traversing carriage 6, the pallet holder 5 returns to the lateral pull position, and when the next molded product E falls from the funnel-shaped guide device WtB to the pallet C, Because the fall is not done properly,
A plurality of suction cups 36 (see FIG. 9) are provided on the upper surface of the traversing carriage 6 to bring the pallet receiver 5 into close contact with the traversing carriage 6.

On the other hand, the lifting carriage 8 to which the rotating arm 7 is attached
As shown in FIG. 9 and FIG. It is supported by a lifting carriage 8 via a spring stack. On the saddle 37, there is a swing bearing 3B integral with the saddle 37, and a swing shaft 3 supported at both ends by the swing bearings 38.
9 and the pivot arm 7 fixed to the pivot shaft 39 are attached. A rotary actuator 40 for rotating the swing arm 7 is provided at both outer ends of the swing bearing 38.
is fixed.

Since the suction force of the suction cup 36 is greater than the elasticity of the stacked springs, the pallet receiver 5 can be suctioned to the traversing carriage 6 by the suction m36. In such a state,
As shown in FIG. 1O, when the pallet receiver 5 is clamped to the lower surface of the rotating arm 7 by the thin cylinder 35, the pallet receiver 5 is fixed to the traversing carriage 6, and as a result, the pallet receiver 5 is fixed to the traverse carriage 6. When the saddle 37 is pushed down, the suction 5136 is released, and the pallet receiver 5 is lifted by the restoring force of the spring stack. Therefore, the pallet support 5 is placed in the vertical position of the lifting carriage 8 without shifting its relative position on the plane. When the rotary actuator 40 operates, the rotating shaft 39, the rotating arm 7, the pallet receiver 5 clamped to the rotating arm 7, and the pallet C and molded product E accommodated in the pallet receiver 5 are moved together into one
Rotate 80 degrees. On the other hand, a l1M rotatable presser cover arm 9 is pivotally supported on the pivot shaft 39, and the presser cover arm 9 is provided with a stopper arm 43 which is appropriately controlled and has a wide opening. The presser cover arm 9 is held by a tension spring 44 and a stopper 49 while the pallet receiver 5 is rotating.

Therefore, when the pallet receiver 5 rotates and the molded product E hits the stopper arm 43 of the presser cover arm 9, the tension spring 4
4 and rotate the presser cover arm 9 together.

This is because when the pallet receiver 5 rotates 180 degrees and stops, the stopper arm 43 of the presser cover arm 9 holds down the molded product E in the pallet C so that it does not fly out.

[About molded product stacking equipment]

A molded product 11 is placed on the opposite side of the lifting column 42 from the lifting carriage 8.
A single stacking device 1D is attached. The molded product stacking device f
iD includes an upper guide tube lO, an upper guide tube bracket 45 that supports it, a lower guide tube 11, a lower guide tube bracket 4G that supports it, and a lower guide tube bracket 4.
It is composed of a lifting guide 50 of 6 and a lower guide lifting air cylinder 47. And the molded product g1m
The molding device is placed close to the conveyor 12 (see Fig. 1), and the upper guide tube lO and the lower guide tube 11 are special tools that are replaced for each molded product E with a different external shape. Therefore, the upper guide tube lO and the lower guide tube 11 are removably mounted on the upper guide tube bracket 45 and the lower guide tube bracket 4C, respectively.

Then, when the stopper arm 43 of the presser cover arm 9 is wide-opened, the molded product E is dropped into the molded product Iam device.
Iair on conveyor 12! I can sleep.

[About the return process]

At the same time, the par arm 43 is retracted and the swing arm 7 is moved to 18'.
It is reversed by 0 degrees to return, and then the elevating carriage 8 is lowered to the lower end. At this time, the lower surface of the pallet holder 5 clamped to the rotating arm 7 is
It stops through a slight gap a with the upper surface of the suction cup 36 on the top of the suction cup 4 (see FIG. 10).

Next, when a suction force is applied to the suction cup 36, the pallet holder 5 pulls down the saddle 37 together with the rotating arm 7 against the spring load.Next, when the clamp of the thin cylinder 35 is released, the pallet holder 5 moves into the elevating carriage. 8, the saddle 37 and the swing arm 7 are pushed up slightly by the elasticity of the spring stack, forming a gap between the upper and lower bifurcated parts of the pallet receiver 5 and the swing arm 7, and returning to the state at the beginning of the flash. Next, the traversing carry/shiro is pulled back to just below the funnel-shaped guide device and stops.

Although a general automatic unloading device is equipped with a sprue cutting device, this device is not shown in this embodiment. It is sufficient to hold the molded product E with a presser lid and cut it from below with an automatic 27 bar.
The pallet C may be a ring-shaped pallet as shown in FIG. 7, or a bucket-shaped pallet as shown in FIG. 10.

Furthermore, the special take-out tools (pallets, upper and lower guide tubes of the stacking device) of this embodiment are designed so that the inside of each special tool is divided into multiple boxes so that multiple molded products can be aligned, taken out, and stacked at the same time. It may be composed of partitions.

In summary, since the present invention adopts the configuration described in the claims, the following effects are achieved.

〔Effect of the invention〕

■ Catches free-falling molded products and carries them upwards.
Therefore, since the molded products are reversed approximately 180 degrees and stacked one after another, the process of taking out the molded products and stacking them can be performed using the same device, which shortens the work process and provides an inexpensive device.

(1) Using a pallet to receive molded products 11111 (or a plurality of molded products at the same time), the molded products are first picked up, pulled horizontally, carried upwards, turned around 180 degrees, and stacked, allowing for accurate stacking.

■ The molded product ejection device does not use conventional suction cup chucks or gripping fingers, but instead uses a wide free-falling guide member, resulting in an inexpensive device and prevents the molded product ejection device from malfunctioning due to mold malfunction. Even if a crushing accident occurs,
The t0 harm can be made minor.

■ A suction cup for pallet suction and a cylinder for pallet clamping are provided to eliminate as much as possible misalignment when transferring pallets from the traverse carriage to the unloading carriage (or vice versa), ensuring reliable operation. Not only can it be transferred, but since the molded products do not shift in position, they can be stacked reliably and contribute to complete automation.

Note that the present invention is not limited to the above-mentioned suction cup and cylinder.

Detailed Description of the Invention [ INDUSTRIAL APPLICATION FIELD The present invention relates to a molded product transfer and stacking device for a plastic molding machine. [Prior art and its problems] Generally, in order to fully automate a plastic molding machine, it is necessary to automatically transfer molded products from a mold. In other words, in plastic molding machines, molded products can fall out of the mold and fall freely, so their removal is difficult compared to other plastic molding machines. Although this is easy to do, complete automation of the molding machine cannot be achieved unless this is done reliably and the individual ronds are aligned in one direction to make it convenient for automatic packaging. For example, in order to eliminate the multi-step operation of inserting a gripping arm between molds, reciprocating movement towards the molded product, and pulling out, or to shorten the take-out operation cycle, proposals have been made to Many proposals have been made, including one configured to automatically take out the molded product by moving the gripping arm mechanically in conjunction with the movement of the goo plate (Japanese Patent Publication No. 53-36866). When taking out the molded product, the conventional one is equipped with a folding device using a robot and a chuck device using an I & board, as shown in Japanese Patent Publication No. 53-9, for example. If this is done, it becomes complicated, and a separate molded product stacking device is required, especially in the case of a chuck device using a suction cup. [Means for solving the problem] The present invention solves the problems of the prior art. It was created for the purpose of The pallet is transferred from the horizontal carriage, and the lifting carriage moves up and down, and at the upper end of the lifting carriage, the carriage is moved approximately
An object of the present invention is to provide a molded product transfer electrical connection device for a plastic molding machine, which is composed of a molded product stacking device into which molded products are placed after being turned 80 degrees and placed on a conveyor. Hereinafter, the structure of the present invention will be explained in detail with reference to embodiments shown in the accompanying drawings. First, the outline of this embodiment will be explained based on FIG. 1. In other words, the injection molding machine 1 injects container-shaped molded products such as plastic barrels, plastic wash basins, lids for plastic barrels, and baskets.
After molding, the molded product remains in the movable mold 4 attached to the side surface of the movable goo plate 3. 2 indicates a stationary mold, and the molded product is dropped from the movable mold 4 using an ejector turbine 5° or an air blower 6° (see Figure 2). It is guided by the described take-out device and turned 90 degrees and allowed to fall freely. That is, this take-out device is composed of a curved guide tube A, a funnel-shaped guide device B, and a receiving pallet C, and the curved guide tube A is inserted between the open molds 2.4.
The molded product remaining in the mold 4 is configured to be moved in an arc from above to cover the molded product before falling down, and
The funnel-shaped guide device B is provided directly below the lower opening of the curved guide tube A, and furthermore, the packet C is provided below the funnel-shaped guide bag vlB and can be pulled horizontally. . After covering the molded product on the curved guide tube, the molded product is separated from the mold 4 by an ejector turbine 5°, an air blower 6°, etc., and the molded product that has fallen is dropped into the curved guide tube A. It is guided, turns 90 degrees, and falls freely. The molded product that is falling is corrected in its falling position by the funnel-shaped guide device B, and falls onto the pallet C, *'fl. The pallet C is mounted on a pallet receiver 5, and the pallet receiver 5 is placed on a traversing carriage 6. When the traversing carriage 6 is pulled sideways, the pallet receiver 5 is inserted into the bifurcated portion at the tip of the swing arm 7 and held by the swing arm 7. Therefore,
Since the swing arm 7 is attached to the lifting carriage 8, when the lifting carriage 8 rises, the swing arm 7,
The pallet receiver 5 and the like are transported upward, and when they reach the upper end, the swing arm 5 rotates 180 degrees while pushing down the presser cover arm 9 that is waiting in the middle of rotation. The molded product stacking device opens at the rotated position. Therefore, by widening the presser cover arm 9, only the molded product E is dropped into the molded product M marketer aO and placed on the conveyor 12. These operations are performed one after another, and the molded products E are stacked one on top of the other. When an appropriate number of molded products E are stacked, the lower guide cylinder 11 of the molded product stacking device rises, and the stacked molded products E are conveyed to a packaging machine or the like by a conveyor 12. Next, these members and steps will be explained in more detail. [About the curved guide tube type] In FIG. 2 and FIG. 3, which is a view from arrow 33 to S3, the devices shown in these figures are curved tube type molded product guide devices that are mainly of the curved guide tube type. , is installed on the die plate 3. When the molded product E is molded and the mold 2.4 is opened, the cylinder 14 on the slider 13 is actuated, and the bending guide tube A descends in an arc shape toward the mold 4 and the molded product E to cover the mold 4 and the molded product E. Next, molding is performed by ejector turbine 5°, air blow 6°, etc. IE is dropped from the mold 4, and the dropped molded product E is rotated 90 degrees by the bending guide tube A and allowed to fall freely. The inner diameter of the curved guide tube A is slightly larger than the outer shape of the molded product E, and it is a special tool for each molded product E (for example, plastic sakaki, bra washbasin, seedling box, basket, container, bucket, etc.). Therefore, the knob 15 and thumbscrew 16 are loosened so that they can be easily removed from the pivot arm 17. In addition, the bending guide pipe Δ is designed to have a 45-degree elbow shape in order to reduce the opening stroke of the mold 2.4, but it is also important to note that the bending guide tube Δ is designed to have a 45-degree elbow shape in order to reduce the opening stroke of the mold 2.4. A 90 degree elbow type may be used for molded parts. Furthermore, in order to facilitate the replacement of the mold 2.4, the crank handle 18 is turned and the vertical feed screw 19 and guide bar 2 are removed.
0, the slider 13 is raised, and then the ratchet handle 21 is turned to move the saddle 23 backward through the left and right feed screws 22, so that the entire saddle 23 is moved backward from the front surface of the movable guide plate 3. . Of course, at this time, the bending guide tube A should be removed. Note that the bending guide tube A shown in FIGS. 4 and 5 is a special tool for flat molded products E such as bra barrel lids, but when this type of flat molded product E is dropped from the mold 4, When passing through the curved guide tube A, it may turn 180 degrees and come out upside down. Therefore, the TI of curved guide tube A! 15~ from the face
When a plurality of thin cylinders 25 are arranged at a 30 degree inclined position, the molded product E is stopped at this position, and then the loft 26 of the thin cylinders is sunk, the molded product E remains as it is. , can fall freely and align in the same direction. Reference numeral 27 indicates an electromagnetic switching valve that operates the thin cylinder 25. [About the funnel-shaped guide device B] In Figs. 3 and 6, the molded product E that leaves the curved guide tube A and falls freely has a funnel-shaped guide ￥i place B directly below it.
Because of this, even if the falling angle position of the molded product E shifts slightly, it will be corrected so that it becomes horizontal at the fixed position. That is, the funnel-shaped guide device B is composed of a funnel 28, and the funnel 2
8 is provided on a frame-shaped fixed block 30 assembled to both horizontal supports 29 of the extraction molding tat, and the block 30 is provided with sliding blocks 32 that slide on slide guide rods 31 assembled on both sides, The sliding block 32 is provided with a handle 33 that connects both blocks, and the forward and backward position of the funnel 28 is adjusted by reciprocating the handle 33. [Regarding Pallet C] In Fig. 7 and its 57 to S7 arrow views, and in Fig. 8, the molded product E that has passed through the funnel-shaped guide device B, has been positioned and dropped, is waiting directly below it. It falls into the ring-shaped pallet C. The pallet C is attached to the pallet receiver 5.
The pallet receiver 5 is placed on a transverse carriage 6/'), and the transverse carriage 6 is mounted on the beam 48.
The top is pulled horizontally by a suitable drive device. The end of the pallet receiver 5 that has been pulled horizontally is inserted into the upper and lower bifurcated space formed at the tip of the swing arm 7, and the inserted pallet receiver 5 is held by the swing arm 7. That is, the ronds of the plurality of thin cylinders 35 provided on the lower surface of the rotating arm 7 protrude, and the pallet receiver 5 is placed on the lower surface of the bifurcated portion of the rotating arm 7.
to press. During this pressing, if the pallet holder 5 is misaligned with respect to the traversing carriage 6, the pallet holder 5 returns to the lateral pulling position, and when the next molded product E falls from the funnel-shaped guide device B to the pallet c, Since the falling is not performed well, a plurality of suction holes 5136 (
(see Fig. 9) is provided, and the pallet receiver 5 is moved by the traversing carriage 6.
Closely contact. On the other hand, the lifting carriage 8 to which the rotating arm 7 is attached
As shown in FIGS. 9 and 10, a saddle 37 that is allowed to move up and down slightly is attached to its front surface, and the saddle 37 has two upper and lower parts that form an equilibrium state in the vertical direction. It is supported by the descending carriage 8 through spring loading.On the saddle 37, a pivot shaft whose both ends are supported by a Mi pivot bearing 38 and a vi pivot co-bearing 38 integrated with the saddle 37 is mounted. 39, and the swing arm 7 fixed to the swing shaft 39. A rotary actuator 40 for rotating the swing arm 7 is fixed to both outer ends of the swing bearing 38. Since the suction force of the suction cup 136 is made larger than the elasticity of the spring stack, the pallet receiver 5 can be suctioned to the traversing carriage 6 by the suction cup 36. In this state,
As shown in FIG. 10, when the pallet receiver 5 is clamped to the lower surface of the rotating arm 7 by the thin cylinder 35, the pallet receiver 5 is fixed to the traversing carriage 6, and as a result, the elevating carriage 8 When the saddle 37 of the example is pushed down, the suction of the suction cup 36 is released, and the pallet receiver 5 is lifted by the restoring force of the spring load. Therefore, the pallet support 5 can be replaced with the lifting carriage 8 without shifting its relative position on the plane.
The lifting carriage 8 rises along the lifting column 42 and stops at the upper end. Then, the rotary actuator 40 is activated, and the rotating shaft 39, the rotating arm 7, the pallet receiver 5 clamped to the rotating arm 7, And the pallet C and molded product E stored in the pallet receiver 5 are together 18
On the other hand, a rotatable presser cover arm 9 is pivotally supported on the pivot shaft 39, and the presser cover arm 9 is provided with a stopper arm 43 which is appropriately controlled and has a wide opening. The presser cover arm 9 is held by a tension spring 44 and a stopper 49 while the pallet receiver 5 is rotating. Therefore, when the pallet receiver 5 rotates and the molded product B hits the stopper arm 43 of the presser cover arm 9, the presser cover arm 9 is rotated together against the tension spring 44. This is because when the pallet receiver 5 stops rotating by 180 degrees, the stopper arm 43 of the presser cover arm 9 holds down the molded product E in the pallet C so that it does not fly out. [Regarding molded product M4 stacking fiD] A molded product stacking device is attached to the opposite side of the lifting column 42 from the lifting carriage 8. The molded product loading device is
The upper guide tube 10, the upper guide tube bracket 45 that supports it, the lower guide ftJ11, the lower guide tube bracket 46 that supports it, the elevation guide 50 of the lower guide tube bracket 46, and the F cylinder for lower guide elevation. 47
It is composed of and. The molded product stacking device tD is arranged close to the conveyor 12 (see FIG. 1), and also has an upper guide tube lO and a lower guide 111?11.
1 is a special tool that is attached to each molded product E having a different external shape. Therefore, the upper guide tube lO and the lower guide tube 11 are attached to the upper guide tube bracket 45 and the lower guide tube bracket 46, respectively. The membrane is freely placed. Then, when the stopper arm 43 of the presser arm 9 is widened, the molded products E are dropped into the molded product milking device and stacked on the conveyor I2. [Regarding the return process to 1] Close the stopper arm 43 and move the swing arm 7 to 180
Then, the elevating carriage 8 is lowered to the lower end. At this time, the lower surface of the pallet holder 5 clamped to the rotating arm 7 stops with the upper surface of the suction 1136 on the traversing carriage 6 through a slight gap a (
(See Figure 1O). Next, when a suction force is applied to the suction cup 36, the pallet receiver 5 pulls down the saddle 37 together with the swing arm 7 against the spring load. Next, when the clamp of the thin cylinder 35 is released, the pallet receiver 5 is released from the lifting carriage 8, and the saddle 37 and the swing arm 7 are pushed up slightly by the restoring force of the spring stack, and the pallet receiver 5 and the swing arm are A gap is formed between the upper and lower forks of 7, and the grip returns to the initial state. Next, the traversing carriage 6 is laterally pulled back to just below the funnel-shaped guide device and stops. Although a general automatic unloading device is equipped with a sprue cutting device, although such a device is not shown in this embodiment, before the pallet receiver 5 is transferred from the traversing carriage 6 to the elevating carriage 8, It is sufficient to hold the molded product E with a presser lid and cut it from below with automatic nippers.
The pallet C may be a ring-shaped pallet as shown in FIG. 7, or a brush-shaped pallet as shown in FIG. 10. Furthermore, the removal-only tools (pallets, upper and lower guide tubes of the stacking device) of this embodiment have a plurality of inner parts inside each dedicated tool so that multiple molded products can be aligned and taken out at the same time and stacked. It may also be composed of partitions divided into squares. In summary, since the present invention adopts the configuration described in the claims, the present invention has the following effects. [Effects of the invention] ■ Catches the free-falling molded product and carries it upward,
So I turned it around 180 degrees and did it one by one! ? ! Because it overlaps,
The process of taking out the molded products and stacking them can be performed using the same device, which shortens the work process and provides an inexpensive device. ■ A pallet that accepts one molded product (or multiple flits at the same time) is used to catch it, pull it horizontally, carry it upward, flip it about 1802 degrees, and stack the bonds, so the stacking can be a positive value. ■ Molding The product ejecting device does not use a suction cup chuck or gripping finger as in the past, but instead uses a simple guide member for free fall, making it an inexpensive device and preventing molded product ejecting from being caught in the vi position due to malfunction of the mold. Even if a pressure accident occurs, the damage caused by it can be minimized. ■ A suction cup for pallet suction and a cylinder for pallet clamping are provided to transfer pallets from a traversing carriage to an elevating carriage (or to We have tried to eliminate positional misalignment as much as possible during the process (reverse), so not only can we ensure reliable transfer, but since there is no misalignment of molded products, we can ensure reliable stacking and contribute to complete automation. Note that the present invention is not limited to the above-mentioned suction cup and cylinder. 4.
