Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for a manufactured product taken out from a mold.

In general, mold demolition is carried out by the punch-out method, in which the cast product is dropped from the flask along with time hardening, the punch-up method, in which the flask is fixed and the cast product is pushed up with time sand from below using a push-up plate, etc.; There is a known extraction method that takes out the cast product by grasping it and pulling it out after separation.
Among these, the extraction method is adopted as an effective method when the casting is a large item.

The present invention provides for intermittent K 1llfi cooling of the castings taken out using the above-mentioned extraction method until cooling packets for each frame.
This invention has been made for the purpose of providing a conveying device that is effective for large-size mold disassembly twins that can be transported, and embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes left and right frames extending in parallel in the front-rear direction, and between the left and right frames 1, a vibrating conveyor table 3 with a sand recovery hopper 2 is arranged extending in the front-rear direction, and a spring 4 is installed. Sand recovery hopper 2
Vibration motors 5 mounted on both sides of the VC are used to apply upward and downward mechanical pressure to the rounding of the cast product W. The conveyance table plate 6 of the finger conveyance table 3 has a small hole or slit for sand to fall, and in this embodiment, the conveyance plate 6 has a central part so that two cast products W can be conveyed in parallel. A partition wall 7 is provided on the upper surface, and side walls 8 are provided on both upper surfaces, and the direction of movement of the cast product W is regulated by these dams 8. Furthermore, the upper surface of the conveyor board 6 returns at regular intervals (it is formed on the surface of the uphill can with a step 9 for stopping, and by mooring the #Kishin W to this step 9 The structure W can be held at a constant position regardless of the application of vibration.

On the side of the carry-in side (the left side in the π1 figure) of the IO transport platform 3, a #made product pedestal 10 is installed, and a fallen product pedestal 101 is used to store products taken out from #inkstones and folded ( After passing through the process of removing the clay channel and sprue from the casting, one frame (in this example, two) of the castings W is placed in a stable sitting position suitable for transportation. . Further, a fixed stand 11 is installed on the side of the unloading side (the right side in FIG. 1) of the vibrating conveyance table 6.Furthermore, on the side of the fixed stand 11, a cooling device is connected in an annular manner on a horizontal plane and is moved intermittently. One packet 120 is facing each other. Although not shown, when loading the casting W into the cooling packet 12, a cooling packet holding device is used to hold the cooling packet 12 so that the cooling packet 12 does not swing.

Next, the cast product W on the cast product holder 10 is transferred to the transfer table plate 6.
The ninth conveying device that pulls the packets upward, sequentially feeds them, and loads them into the cooling packets 12 will now be described.The left and right upper frames 13 extend in the front-rear direction parallel to the cough frame 1 above the frame 1. are supported by pillars 14, and rails 15 are fixed to each of them, and on the rails 15 there is a rectangular frame shape longer than the carrier plate 6 for progressively feeding castings. No. 1:
, 1 A feed cart 16 is placed on the cart so that it can be horizontally reciprocated via a pair of front and rear wheels 17 placed on both left and right sides of the feed cart 16. A support frame 18 for the cylinder is framed on the upper center surface of the feed truck 16, and a bracket 1 is mounted on the upper part of the support frame 18.
A piston rod 21 of a feed cylinder 20 attached via a shaft 9 is connected to a beam 22 installed between the upper portions of the left and right columns 14. That is, the feed truck 16 is moved forward and backward by the operation of the feed cylinder 20 with a stroke fL that is slightly larger than the interval of the array 11Jl of the stepped portions 9 for preventing return on the conveyor plate 6, and when moving backward, the It has a length such that the rear part reaches above the casting holder 10 when it moves the most towards the carry-in side, and the front part reaches above the cooling packet 12 when it moves to IIT.

Further, groove-shaped rails 23 are formed on the inner surfaces of the left and right frames of the feed truck 16 over the entire length thereof,
Further, on the lower surface of the side frame, rotary shafts 24 which are slightly shorter than the carrier plate 6 and which extend parallel to the front and rear surface pressures are rotatably attached via bearings 25. A plurality of feed pawls 26 are vertically provided in parallel at intervals equal to the arrangement interval of the stepped portions 9 of the conveyor plate 6. Therefore, a feed cylinder 27 is attached to a bracket 28 at the center of the outside of both side frames of the feed truck 16.
The piston rod 29 of each force-feeding claw cylinder 27 is connected to an interlocking arm 60 protruding from the rotating shaft 24 . That is, each of the feed pawls 26 is swung in the left and right direction in unison by the operation of the feed pawl V cylinder 27, and has two positions: a feed position where the cast product W enters the conveyor line, and a retracted position where it deviates from the conveyor line. It is designed to be displaced to

Further, on the carry-in side of the feed cart 16, there is a pull-in cart 31 for pulling the casting W on the casting pedestal 10 onto the perturbation conveyor 5, and on the carry-out side, there is a pull-in cart 31 for cooling the casting W on the fixed table 11. Loading carts 38 for loading the packets 12 are installed respectively. The retractable cart 51 is formed into a small frame shape that fits within the frame on the garden side of the feed cart 16, and is horizontally attached to the rail 23 of the feed cart 16 via an appropriate number of wheels 32 arranged on both sides of the frame. It is mounted on an extractor that can be moved back and forth. A retraction cylinder 33 for moving the retraction truck 61 forward and backward is attached to the support frame 18 of the feeder truck 16 via a placket 34, and its piston rod 65 is connected to the retraction truck 61 via a placket 36. On the lower surface of the rear end of the pull-in truck 31, there are two left and right pull-in claws 37 hanging down for drawing the cast product W onto the vibrating conveyor table 6. In this state, that is, when the forward end is reached, the rear feed pawl 26 of the feed truck 16 also moves forward.
The spacing between the feeding pawls 26 is set to be equal to the spacing between the feeding pawls 26.

On the other hand, the loading cart 38 is formed into a small frame shape like the retracting cart 61, and has an appropriate number of wheels 39 on both sides.
The piston rods are mounted on the rails 23 of the feed truck 16 so as to be horizontally reciprocating, and the piston rods are connected to each other by the joint 4.
The loading cylinders 40 and 41 are directly connected to each other through the cylinders 40 and 41, and the loading cylinders 40 and 41 move forward and backward. That is, one first loading cylinder 40 is supported by the support frame 18 of the feeder east 16 via a placket, and the other first loading cylinder 40 is supported by the loading truck 38 via a placket 43. . On the lower surface of the front end of the loading cart 58, there are a pair of clamp arms 45, one on each left and right, each having a clamp claw gap at the lower end for grasping the casting W on the fixed base 11 and loading it into the cooling packet 12. It is attached. Each clamp arm 45 is fixed to one end of an arm shaft 47 rotatably attached to the lower surface of the loading truck 68 via a bearing 46, and a pair of left and right arm shafts 46 for each set is attached to the other end. They are interlocked by fixed gears 48, which drive the clamp cylinder 49.
The swinging (opening and closing) actions for gripping and releasing the clamp arm 45, which is the source, are synchronized. In addition, a placket 50 is attached to the upper front end of each 49-clamp cylinder loading cart 38.
The piston rods 51 are connected to interlocking arms 52 fixed to one shaft end of a pair of arm shafts 47, respectively.

As for the loading truck 58, when the feed truck 16 is at the rearward end and only the second loading cylinder 41 is extended, the clamp arm 45 is located directly above the fixed base 11, that is, at the kufunde position. When the feeding truck 16 is at the forward end (at the forward end and both the first and second loading cylinders 40, 41 are extended), the clamp arm 45 is inserted into the cooling packet 12, and both loading cylinders are extended. cylinder 40.41
Both loading cylinders 40,41
The stroke of the clamp arm 45 and the position of the clamp arm 45 are set. Both the first, wl, and second loading cylinders 40, 41 and the clamp cylinder 49 are kept in a contracted state until the cast product W is actually transported onto the fixing table 11 after the start of this transport device. The W! It is controlled by a built-in product presence detector (not shown). That is, at the beginning of operation, the loading operation @r is stopped and the clamp arm 45 is
This is to prevent interference with the castings of small objects loaded in the cooling packet 12 by preventing the insertion of the small objects into the cooling packet 12. This is a cooling packet in which a pull-out type disassembly fin for large objects, which is the object of the present invention, and a separate punch-out type disassembly fin for small objects are chained in a ring and are circulated and transferred intermittently. In a layout in which group 12 is shared, and the casting loading position of the punch-out type release fin in the cooling packet group is set upstream of the punch-out type release line, This is because, immediately after switching the type of use type Gelashi Twin from one for small items to one for large items, some of the cooling packets 12 that face the fixed base 11 in sequence are actually loaded with small items.

This embodiment is a book configured as described above, and its operation will be explained below. As shown in Fig. 7, each trolley 16, 31
．． 38 are all waiting at the retreat end and the feed claws 26 are closed, the cast product W is pulled out from the mold and has undergone the weir folding process to remove the clay runners, hot water spots, etc., and is suitable for stable conveyance. When the cast product is placed on the casting pedestal 10 in a state where it has been changed into a posture, the retracting cylinder 33 is operated to contract, and the feed cylinder 2o is subsequently operated to extend, so that the feed cart 16 and the retracting cart 51 are moved. Since the eaves are moved forward, the retracting claw 37 moves forward with the strokes of both the feed cart 16 and the retracting cart 31, and moves the casting W on the casting holder 1° to the transfer table plate 6 of the vibrating transfer table 5. Bring it upstairs. Note that at this point, both the first and second loading cylinders 40, 41 maintain the operation set and contracted state for the reason described above, so the clamp arm 45 does not enter the cooling packet 12 (the When the feed truck 16 reaches the forward end (see imaginary line in the figure), when the feed truck 16 reaches the forward end, the feed pawl cylinder 27 is contracted, and the feed pawls 26 are all swung to the retracted position at the same time as shown by the temporary push line in FIG. In this state, the feed cylinder 2o is contracted, the retraction cylinder 35 is extended, and the feed truck 16 and the retraction truck 61 are returned to their original positions, and at the backward end, the feed pawl cylinder 27 is extended, so that each of the feed pawls 26 is dynamically displaced to the feeding position shown by the solid line in FIG. 3 in preparation for feeding the casting W.

While the molding fins are in operation, the iI molded product W on the conveyor plate 6 is constantly subjected to vertical vibration to remove sand by the vibration sweater 5, but as described above, the upper sloped surface and the stepped portion 9 facing the feeding side are This prevents it from moving and keeps it in place. Note that since the cast product W is always thrown off by this vertical vibration, an extremely small pressing force for conveying and moving may be sufficient. Subsequently, when the casting W is placed on the casting cradle 10, the above action is performed again, and the casting W on the casting cradle 10 is carried onto the conveyor plate 6 by the retracting claw 67. Also, the casting W on the conveyor plate 6 is fed one pitch by the feeding claw 26. Below, casting product W
The same action is repeated each time a cast product is placed on the carrier plate 10.
When the pieces are sequentially fed one by one and transferred onto the fixed base 11 by the frontmost feeding claw 26, the detector detects this and the first and second loading cylinders 40°': 1 41 and a signal allowing the cranking cylinder 49 to start operating.

Therefore, after that, when the power feeding truck 16 and the retracting truck 51 return to the backward position, only the second loading cylinder 41 is extended and the loading truck 68 is moved from the backward end to the final position, that is, the clamp arm 45 is moved to the fixed position. When the clamp arm 4.5 is moved forward to a position directly above the clamp arm 11, the sleep pump cylinder 49 is activated and the clamp arm 4.5 is moved to a position directly above the clamp arm 4.5.
1 and prepares for the next conveyance (refer to the state shown in FIG. 1).

In such a state, when the next conveyance operation is performed, that is, the feed cart 16 and the retracting cart 31 are moved forward, this! 1st
In order to move the loading truck 38 forward by extending the loading cylinder 40 tons, the retracting pawl 37 carries the casting W onto the conveyor plate 6, and the feeding pawl 26 sequentially feeds the product W. moves forward with a stroke that is the sum of the stroke of the feed truck 16 and the stroke of the first loading cylinder 40 of the loading truck 38, and loads the casting W into the cooling packet 12 (see FIG. 6). Thereafter, the clamp is released by the contraction operation of the clamp cylinder 49, and the feed claw 26 is moved to the retracted position by the feed claw release cylinder 27, and then each carriage 16. ．． 51.38 are returned to their original positions by the contraction operation of the cylinders 20 and 40.41 and the extension operation of the cylinder 66, respectively. In this case, the second loading cylinder 41 of the present embodiment is once compressed and then the other cylinders 20 and 40 are moved forward to advance the clamp arm 44 until the clamp is released.
The extension operation is performed prior to the extension operation of the cylinder 33 and the contraction operation of the cylinder 33, but after the osteotomy casting W to be transferred to the fixing table 11 is detected, the extension state is maintained. It is also possible to use a method.

Furthermore, the method in which the loading cart 38 is moved forward and backward using two connected cylinders is effective when the pull-out type mold disassembly line and the punch-out type mold disassembly fin of the present invention share a group of cooling packets, as described above. However, if the packet group is not shared, or if the packet group is circulated even if the packet group is shared, the loading position of the punch-out type type disassembly twin is set upstream from that of the punch-out type disassembly fin. In this case, the second loading V cylinder 41 can be omitted. In addition, the castings W are loaded into the cooling packet 12 by a sequential feeding method such as the illustrated Kufunde claw method.]
There is no problem even if you change to the claw method, and the cast product W for 91 frames.
Although the explanation is made assuming that there are two cases, the present invention is not limited to this.

As described in detail above, the present invention is used as a rounding conveying device for loading castings pulled out of molds into cooling packets in a pulling-up type mold disassembly line. In addition to providing the cart so that it can be horizontally reciprocated, a retractable cart with a retracting claw is provided on one side of the feeding cart, and a loading cart with a loading claw is provided on the other side so as to be movable horizontally. , After the manufactured articles placed on the article cradle are carried onto the conveyor table, they can be transported sequentially and loaded into cooling packets one after another. In addition, by adopting the above configuration, the entire device can be arranged compactly and
It is now possible to freely set the loading pitch from the top of the product holder to the conveyor table, the rebitch on the conveyor table, and the loading pitch from the conveyor table to the cooling packet. This is advantageous in performing the overall layout of the deformed fins.
