Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention mounts an upper model and a lower model with a carrier which is attached to a model attaching / detaching station of a mold molding line and moves on the mold molding line. The present invention relates to a model setup device in a mold forming line that exchanges placed plates.

(Prior Art) Generally, in a continuous casting line using a sand mold, a molding line for continuously molding a mold is provided. This molding line is made as follows.

First, a plate (hereinafter, referred to as a plate) on which an upper model and a lower model required for each mold product are fixed is set in a carrier, and the carrier is set in an upper model forming machine and a lower model forming machine.

A predetermined number of molds are formed by the upper and lower molding machines, and then the carrier is returned to the loading / unloading station.

At the attaching / detaching station, the shaping completed plate is taken out of the carrier, and the next expected plate is set. Hereinafter, the same operation is repeated. still,
The shaped mold is carried to a pouring step.

By the way, the size of the plate, which depends on the size of the cast product, or the production quantity, for example,
There are various sizes, such as 1/1, 1/2, and 1/4, for the size 1 of the carrier. Then, upon modeling, these are appropriately combined in consideration of each production quantity.

(Problems to be Solved by the Invention) According to the above conventional technology, the work of assembling and attaching and detaching the plates is complicated, and the work takes a long time,
In some cases, the plates may be combined in an incorrect arrangement or direction, and there is a problem that molding defects occur.

That is, as described above, there are plates of various sizes, and the worker considers the correspondence between the upper model and the lower model, and also considers the direction of the runner to be connected to the gate. This is because plates of different sizes must be appropriately combined and arranged.

Further, when transporting the plate, a hoist or the like is used for heavy objects, and the position of the plate must be set by suspending the plate with the hoist, so that a difficult operation has to be performed.

The present invention has been made based on such a point, and an object of the present invention is to provide a model setup device in a mold forming line capable of performing a model setup operation quickly and reliably. is there.

That is, it is necessary to make the lower mold and the upper mold exactly correspond to each other, and as shown in FIGS. 14 (a) and (b), the upper mold is replaced with the lower mold. This is the reason why they are combined in a predetermined order different from that of the application.

 The operation of the embodiment will be described based on the above structure.

First, the combination operation in the case of using the quarter plate 63 will be described with reference to FIG. As shown in FIG. 16 (a), the 1/4 plate 63 shown in the figure is of a vertical type and is fed into the distribution traverser 37 from the loading roller mechanism 61. The lower mold is sent to the roller mechanism 73 of the transport means 5, and the upper mold is sent to the standby means 3.

By such an operation, the state shown in FIGS. 16 (h) and 14 is obtained.

Next, an operation of taking out a used plate (for example, a quarter plate 63) from the carriers 9, 9 will be described. 17th
As shown in the drawing, the plate 63 in the carrier 9 is pushed up above the carrier 9 by the plate pushing mechanism 153. In this state, the traveling base 109 of the removable traverser 106 travels in the direction of the carrier 9. By the traveling of the traveling base 109, the roller mechanism 125 is inserted below the plate 63.

Next, as shown in FIG. 18, when the plate pushing mechanism 153 is lowered, the plate 63 is placed on the roller mechanism 125.

Next, the plate transfer mechanism 135 moves in the direction of the carrier 9, and the plate retrieving mechanism 139 operates to lower the operating part 147 thereof. In this state, if the plate transfer mechanism 135 is retracted, the four plates 63
Placed on 17 This operation is performed separately and simultaneously by a pair of movable traversers 106 and 106 for the upper and lower dies.

Next, the taken-out plate 63 is moved onto the roller mechanisms 91 and 93 of the moving means 7. That is, as shown in FIG. 19, the traveling base 77 of the movable traverser 74 is caused to travel, and the roller mechanisms 91 and 93 are arranged at predetermined positions. In this state, as shown in FIG. 20, the plate 63 may be sent out onto the roller mechanisms 91 and 93 by driving the roller mechanism 117.

The traveling base 77 of the moving means 7 travels in the direction of the unloading means 13, positions the roller mechanisms 93 and 91 at locations corresponding to the unloading means 13, and sends out the plate 63 to the unloading means 13. At this time, the feeding from the transport means 5 to the moving means 7 proceeds simultaneously (FIG. 21). Thus, the removal of the used plate 63 is completed.

Next, the operation of attaching the plate 63 before use to the carriers 9 will be described. First, the roller mechanism of the moving means 7
On the plates 87 and 89, the plates 63 before use combined and sent by the conveying means 5 are placed. And the running base
77, and as shown in FIG.
87, 89 are located at locations corresponding to the removable traversers 106, 106.

In this state, the plate 63 is sent out onto the roller mechanism 117 of the removable traversers 106, 106 by driving the roller mechanisms 87, 89 as shown in FIG.

Next, as shown in FIG. 23, the traveling base 109 of the detachable traverser 106 is moved in the direction of the carrier 9.

Next, as shown in FIG. 24, the plate delivery mechanism 137 of the plate transfer mechanism 135 is driven to lower the operating part 143 thereof. Then, the plate 63 is moved above the carrier 9 by moving the plate transfer mechanism 135 in the direction of the carrier 9. At this time, the plate is stopped by the positioning mechanism 127. Next, the operating section 143 is raised, and the plate transfer mechanism 135 is returned to a predetermined position. Next, the plate pushing mechanism 153 is driven to raise each pushing pin 157. Thus, the plate 63 can be supported by the pins 157.

In this state, when the traveling base 109 is retracted as shown in FIG. 25, the plate 63 is in a state of being supported by the push-out pins 157. Thereafter, when the push-out pin 157 is lowered, the plate 63 is automatically mounted in the carriers 9, 9.

Thereafter, the same operation is repeated to exchange a plate with the carrier 9.

Although the description has been made by taking the 1/4 plate 63 as an example, the same order is used when plates 35 and 36 of other sizes are used.

According to this embodiment, the following effects can be obtained.

First, since the plate transfer operation, which has conventionally been performed manually, can be performed automatically, the burden on the operator can be reduced. In addition, the occurrence of defective products due to erroneous work can be prevented.

Further, since a hoist or the like which has been conventionally required can be made unnecessary, the space can be effectively used.

The loading means 1 is provided with a distribution traverser 37 for handling the 1/4 plate 63. By using the distribution traverser 37 and the standby means 3, the operation of assembling the 1/4 plate 63 can be easily performed. it can. Since the direction of each plate for taking the plate 63 into the carry-in roller mechanism 61 is unified, the direction can be set by the distribution traverser 37 depending on where to place the carrier 9.

Further, a positioning mechanism 127 is provided in the detachable traverser 106, whereby the plate can be accurately positioned at an appropriate position.

(Effects of the Invention) As described in detail above, according to the model setup device in the mold making line according to the present invention, it is possible to automatically perform the transfer of the plate, which has been conventionally performed manually, thereby facilitating the operation. And the time required for the operation can be reduced. Further, erroneous work can be eliminated, and occurrence of defective products can be prevented.
