Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ingot manufacturing line used as a casting molding material such as die casting.

[0002]

[Prior art and its problems]

 As shown in FIG. 1, this type of ingot manufacturing line is a molten metal distributor (not shown) installed on the starting end side of a forming conveyor 1 in which a large number of ingot forming dies are mounted in parallel in the moving direction. The molten metal in each ingot mold 1a is distributed and supplied to each ingot mold 1a by the container, and the molten metal in each ingot mold 1a is naturally solidified during the process of transporting each ingot mold 1a to the end of the molding conveyor 1 A shock is applied to each ingot mold 1a as if it were hit with a hammer by the demolding device 6 installed in the mold. The mold is demolded from each ingot mold 1a and synchronized with the conveying speed of the molding conveyor 1 It is received on the transfer conveyor 2 installed below. The ingot 5 received on the delivery conveyor 2 is transferred to the end portion of the conveyor 2 and is spontaneously dropped from the end portion to the guide roller 4 installed in front of the ingot 5 so as to be synchronized with the transfer speed of the delivery conveyor 2. It is transferred to the cooling conveyor 3 installed below it, and is transferred to the cooling water tank 7 by the cooling conveyor 3 for forced cooling. By the way, the ingot received from each ingot forming die of the forming conveyor on the delivery conveyor is allowed to spontaneously drop from the end of the conveyor to the guide roller, slipping off the roller and being inverted when delivered to the cooling conveyor. However, the ingots of different materials (product types) have different sliding conditions (speed) for sliding down the guide rollers, although they are transferred between the latching claws 3a that project at regular intervals on the cooling conveyor. In other words, in the case of an ingot formed of a material with good slip, the guide roller slides down quickly, but in the case of an ingot formed of a material with poor slide, it does not easily slide off the guide roller. .. Therefore, the transfer timing of transferring the ingot at the same speed from the end of the transfer conveyor to the cooling conveyor is shifted, and the ingot cannot be transferred reliably between the hooks 3a of the cooling conveyor. As a result, the ingot rides on the hooking claw, and is moved down into the cooling water tank by the cooling conveyor and is forcibly cooled and then moved up from the water tank to the packing line for stacking multiple ingots and band-wrapping. In the process, the ingot fell off from the cooling conveyor, and the production line had to be stopped and the ingot dropped, and some other work had to be done to restore it and restart it. In addition, when the ingot slides down the guide roller and moves onto the cooling conveyor, it jumps up due to the collision force of the ingot, and climbs over the latching pawl, or over the latching pawl and one end side of the ingot moves to the next or There is also a problem that it is not possible to transfer regularly between the hooks at appropriate positions on the cooling conveyor, such as getting caught between the hooks in the foreground. I had to get the production line running while making the modifications.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such conventional problems, and the technical problems to be solved are different depending on whether the ingot is made of a material having poor sliding properties or the ingot formed of a material having good sliding properties. Depending on the sliding condition (speed) of sliding down the guide roller, you can change the falling timing of the ingot from the end of the transfer conveyor to the guide roller with a simple operation to place the ingot between the hooks at the appropriate positions on the cooling conveyor. It can be reliably delivered, and while holding the ingot's bounce up due to the drop collision force when sliding on the guide roller and transferring onto the cooling conveyor, place the ingot between the hooks at appropriate positions on the cooling conveyor. An ingot manufacturing line equipped with an ingot delivery control device that can be stored in a regular manner An object of the present invention is to provide.

[0004]

[Means for achieving the object]

 The technical means taken by the present invention to achieve the above object is to install an ingot delivery control device at the conveyor end side of the delivery conveyor installed between the molding conveyor and the cooling conveyor, and to control the ingot delivery. The device is movable forward and backward from the end of the delivery conveyor, and an ingot guide member that receives the ingot together with the conveyor, an operation handle that moves the ingot guide member forward and backward, and a front and back forward from the end of the delivery conveyor. It is characterized in that it comprises an ingot pressing member rotatably supported by a front end portion of an ingot guide member which is movably protruded so as to vertically extend toward a cooling conveyor.

[0005]

[Action]

 Thus, according to the above-mentioned technical means of the present invention, when manufacturing an ingot from a slippery material, the operation handle of the ingot delivery control device is turned to move the front end of the ingot guide member to the end of the delivery conveyor. By significantly changing the amount of protrusion from the part to the front, the timing at which the ingot falls onto the guide roller is delayed, and when manufacturing an ingot from a material with poor slipperiness, turn the operating handle to move the ingot guide member. By changing the amount of protrusion of the front end from the end of the delivery conveyor to the front, the ingot can be dropped onto the guide rollers earlier. As a result, the guide roller is adjusted to the falling timing according to the sliding condition (speed) of the sliding ingot, and the ingot slides on the cooling conveyor at a speed synchronized with the transfer speed of the cooling conveyor. In other words, the latching pawls protruding at regular intervals on the cooling conveyor pass under the guide rollers, and the latching pawls at appropriate positions are adjusted so that the ingot slides down onto the cooling conveyor in accordance with the passage timing. Make sure to put the ingot in between. When the ingot slides down the guide roller and is transferred onto the cooling conveyor, the ingot holding member holds up the bounce caused by the drop impact force so that it is regularly placed between the hooks.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. A molding conveyor 1, a transfer conveyor 2, a cooling conveyor 3, a guide roller 4 have a well-known structure and are molded by each ingot molding die 1a of the molding conveyor 1. The impacted ingot 5 is applied to each ingot mold 1a as if it was hit with a hammer of the demolding device 6, and the ingot 5 is demolded from each ingot mold 1a and received on the transfer conveyor 2 and the transfer conveyor 2 After being transferred to the end portion of the cooling roller 3, the guide roller 4 is slid down from the end portion to the guide roller 4 to slide down, and between the latching claws 3a projecting at a constant interval on the cooling conveyor 3. It is transferred to the cooling water tank 7 by the cooling conveyor 3 and is forcibly cooled. Installing deploy ingot transfer control device 8 on the end side.

The ingot delivery control device 8 controls the falling timing of the ingot 5 that naturally falls from the terminal end of the delivery conveyor 2 to the guide roller 4, and also slides down the guide roller 4 to transfer onto the cooling conveyor 3. It acts to prevent the ingot 5 from bouncing up by the drop impact force of the ingot 5, and can be moved forward and backward from the terminal end of the delivery conveyor 2 together with the conveyor 2 from each ingot forming die 1a of the forming conveyor 1. The ingot guide member 8a for receiving the ingot 5, the operation handle 8b for moving the ingot guide member 8a back and forth, and the front end of the ingot guide member 8a projecting forward from the end of the delivery conveyor 2 are rotatable. The ingot retainer that is rotatably supported by the shaft and vertically hung down toward the cooling conveyor 3. It consists of a wood 8c.

[0008] The ingot guide member 8a is two round bar members cut into appropriate lengths, and these two round bar members are mounted on the installation base 8d mounted on the machine frame 9 with bolts 10 and delivered to the delivery container. The supporting plates 8e arranged at the front and rear of the yard 2 at intervals of the conveyors (both chains in the drawing) are fitted and supported so that they can be moved back and forth, and the rear ends thereof are connected by the connecting plate 11 to connect the connecting plates. 11 and the operating handle 8b is installed over the standing plate 12 fixedly erected at the center of the installation base 8d, and the front end thereof is connected by the connecting rod 13 to attach the ingot pressing member 8c to the connecting rod 13. A pivot support is attached so that it can rotate freely.

The operation handle 8b is configured such that the front end portion of the ingot guide member 8a is projected forward (to the guide roller 4 side) from the end end portion of the delivery conveyor 2 or is recessed rearward from the end portion. 8a is slid back and forth to adjust the falling timing of the ingot 5 onto the guide roller 4 appropriately. It is operated from the middle of the axial direction to the rear end of the long screw rod 14 with a male screw engraved on the outer circumference of the front end. The rod 15 is fixedly attached to form a substantially T-shape, and the rear end side of the long screw rod 14 to which the operating rod 15 is attached can be freely pivoted to a standing plate 16 fixedly erected in the center of the connecting plate 11. It is supported by penetrating it in a fixed state in the front-rear direction, and is threadedly fitted into the female screw hole 17 of the upright plate 12 fixedly installed at the center of the installation base 8d (see FIG. 3).

The ingot pressing member 8c functions to prevent the ingot 5 from jumping up due to a drop collision force when the guide roller 4 slides down and is transferred onto the cooling conveyor 3, and is cooled from the end portion of the transfer conveyor 2. A weight 19 corresponding to the weight of the ingot 5 is attached to the lower end edge of the hanging plate 18 having a length (height) that is approached toward the conveyor 3 and a width corresponding to the interval between the ingot guide members 8a on both sides. A pipe 20 rotatably fitted to and mounted on a connecting rod 13 that connects the front end of the ingot guide member 8a, and the upper end edge of the ingot guide member 8a is hung down toward the cooling conveyor 3 and brought closer to the ingot guide member. It is attached so that it can rotate freely over the front end of 8a.

Next, an example of how to use the ingot delivery control device configured as described above will be described. The installation base 8d is attached to the machine frame 9 with bolts 10 and the ingot guide member 8a is installed between the delivery conveyors 2. And an ingot delivery control device 8 on the terminal end side of the delivery conveyor 2 in a state of being substantially flush with the conveyor level (chain level) (see FIG. 2). When manufacturing the ingot 5 of the slippery material by supplying the molten metal of the slippery material to the ingot molding die 1a of the molding conveyor 1, the operation handle 8b is turned to transfer the front end of the ingot guide member 8a to the transfer conveyor. The amount of protrusion from the end of 2 to the front is increased as shown by the chain double-dashed line in FIG. As a result, the ingot 5 received from the ingot molding die 1a of the molding conveyor 1 on the delivery conveyor 8a and transferred to the terminal end of the conveyor 8a is projected forward without dropping from the terminal end. The ingot guide member 8a is transferred to the front end portion and dropped from the front end portion to the guide roller 4 (see FIG. 4), and the guide roller 4 is slid and transferred between the hooks 3a of the cooling conveyor 3. To do. That is, by changing the front end portion of the ingot guide member 8a so as to increase the protrusion amount from the terminal end portion of the delivery conveyor 2 to the front side, the timing of dropping the ingot 5 from the delivery conveyor 2 to the guide roller 4 is delayed. When manufacturing the ingot 5 made of a material with poor slipperiness while delivering it between the hooks 3a of the cooling conveyor 3, the front end of the ingot guide member 8a is projected forward from the end of the delivering conveyor 2. By changing the amount so that it is smaller than the case of the ingot 5 with good slippage, the timing at which the ingot 5 falls onto the guide roller 4 is accelerated and the ingot 5 is transferred between the hooks 3a of the cooling conveyor 3. To Then, when the ingot 5 dropped from the delivery conveyor 2 slides down on the guide roller 4 and is transferred to the cooling conveyor 2, the ingot 5 is pressed down from the position immediately before sliding down on the cooling conveyor 3 until it is securely set between the hooks 3a. It is pressed by the member 8c to prevent the ingot 5 from jumping up due to a drop impact force so that the ingot 5 is regularly housed between the hooks 3a (see FIGS. 5 and 6).

Thus, according to the ingot manufacturing line of this embodiment, the operation handle 8b of the ingot delivery device 8 installed and arranged on the terminal end side of the delivery conveyor 2 is turned to deliver and deliver the front end of the guide member 8a. By performing an operation so as to change the amount of protrusion from the end of the conveyor 2, the ingot 5 is dropped from the transfer conveyor 2 to the guide roller 4 at a drop timing according to the sliding condition (speed) of the ingot 5 sliding down the guide roller 4. Thus, the ingot 5 can be transferred onto the cooling conveyor 3 at the same transfer speed of the cooling conveyor 3. That is, the ingots 5 are adjusted so that the ingots 5 slide down from the guide rollers 4 onto the cooling conveyor 3 in accordance with the passage timings at which the latching claws 3a protruding at a constant interval of the cooling conveyor 3 pass under the guide rollers 4. The ingot 5 can be reliably placed between the hooks 3a at appropriate positions. Moreover, when the ingot 5 slides down on the guide roller 4 and is transferred onto the cooling conveyor 3, the ingot 5 can be regularly accommodated between the latching pawls 3a by holding down the bounce caused by the drop impact force by the ingot pressing member 8c. ..

7 to 9 show other embodiments of the ingot delivery device 8, respectively, and FIG. 7 shows an ingot pressing member 8c which is curved as shown in the drawing so that it can be rotated to the front end of the ingot guide member 8a. The ingot 5 is slidably mounted so that the ingot 5 slides down on the guide roller 4 and presses it in the middle so that the ingot 5 does not fall to the cooling conveyor 3 side due to the impact force when the ingot 5 spontaneously falls on the guide roller 4. It was done. In other words, the ingot 5 that falls from the delivery conveyor 2 while being inverted falls on the cooling conveyor 3 in the same posture as that on the delivery conveyor 2 in which the ingot 5 falls to the cooling conveyor 3 side without sliding down the guide roller 4 and is inverted. The certainty of the delivery is improved so that the passenger does not get on the vehicle. By the way, if the ingot 5 rides on the cooling conveyor 3 in the same posture as that of the delivery conveyor 2, a problem in operation in a packing line where a plurality of ingots 5 are stacked and band-fixed, for example, a predetermined number is arranged in a line. However, when stacking several stages and banding them, the photoelectric sensor with the ingot that is sequentially transferred to the packing line by the cooling conveyor 3 as a cant has a different reflection state depending on the front and back sides. Cause problems. In FIG. 8, the front end portion of the ingot guide member 8a is curvedly extended as shown in the example, and when the ingot 5 is naturally dropped onto the guide roller 4, the curved extension portion 8a 'is slidably dropped to guide the guide roller 4a. By suppressing the impact force when it falls into the ingot and at the same time making the gap with the guide roller 4 close to the thickness of the ingot, it is possible to suppress rattling of the ingot when falling and to slide down smoothly along the guide roller 4. .. FIG. 9 shows that the front end of the ingot guide member 8a and the ingot pressing member 8c are curved as shown in FIGS. 7 and 8 to make sure the delivery of the ingot to the cooling conveyor 3 by the synergistic action of both. It is an improved layer.

[Effect of the device]

 Since the production line of the ingot of the present invention is constructed as described above, it has the following operational effects.

An ingot guide member, which is movable forward and backward from the end of the delivery conveyor and receives an ingot, is provided on the conveyor end side of the delivery conveyor installed between the molding conveyor and the cooling conveyor, and the ingot guide member. The operating handle for moving the guide member back and forth and the front end of the ingot guide member, which projects forward and backward from the end of the transfer conveyor, are rotatably pivoted and hung down toward the cooling conveyor. Since an ingot delivery control device composed of an ingot pressing member is installed, the operation handle of the ingot delivery control device is turned and the front end of the ingot guide member is delivered to the front end of the delivery conveyor, and the amount of protrusion to the front is greatly changed. The delivery conveyor to guide It is possible to delay the timing of the ingot falling onto the roller, and by rotating the operation handle, the front end of the ingot guide member is changed slightly from the end of the transfer conveyor to the front, so that the transfer conveyor moves to the guide roller. It is possible to accelerate the falling timing of the ingot. That is, each hook that protrudes at a certain interval on the cooling conveyor passes under the guide roller, and the ingot slides down onto the cooling conveyor in accordance with the passing timing. The ingot falls according to the sliding condition (speed) of the ingot. It can be adjusted so that the ingot drops from the transfer conveyor to the guide roller at the timing. Moreover, when the ingot slides down on the guide roller and is transferred onto the cooling conveyor, the ingot holding member can prevent the bounce up due to the impact force of the drop, so that the ingot can be securely fit between the hooks.

Therefore, according to the present invention, depending on the sliding condition (speed) of sliding down different guide rollers depending on the ingot molded from a material with poor slip and the ingot molded from a material with good slip, By changing the falling timing of the ingot from the end part to the guide roller with a simple operation, the ingot can be reliably delivered between the latching pawls at the appropriate positions of the cooling conveyor, and the guide roller slides down. Ingots that can solve all the problems in the past, in which the ingots can be housed regularly between the latching pawls at appropriate positions of the cooling conveyor while suppressing the bounce of the ingot due to the drop collision force when transferring onto the cooling conveyor, It becomes a production line.
