Abstract

PURPOSE:To enhance productivity and respectively give optimum molding conditions and keep proper molding cycles even in a case that two or more types of articles different in molding conditions are molded with a single molding equipment by a structure wherein a standby station is provided at the foregoing stage of a preheating station so as to proceed each mold one by one station independently from other mold. CONSTITUTION:By releasing to stopper of a standby station 8, molds are brought into the state rollingly shiftable on travelling rails. By shifting a handling device, a mold 90 is loaded on a lift conveyer 57 to be shifted to a standby station 9 for standing-by. When a detection device recognizes that no mold is present in a preheating station 1, the mold is shifted to the mold rotating device 17 of the preheating station 1. After that, by rotating the prime mover 19 of the rotating device 17, the mold is heated with hot air blasted from hot air blasting nozzles or small orifices 16. After heating by timing for a certain period of time, the presence or absence of a mold in the following process or in a first casting station 2 is detected so as to convey the mold in the first casting station 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a slush molding device, and particularly to a slush molding device suitable for automated production of a wide variety of slush molded skins.

(Prior art) Conventionally, equipment for automated production of slush-molded skins consists of a conveyor on which a large number of molds are successively mounted at regular intervals, a preheating device arranged at the same intervals as the molds on the conveyor, and a casting machine. There is known an apparatus in which a conveyor is moved in small increments every time all processes are completed by combining a molding apparatus, a curing heating apparatus, etc., and the molds are conveyed one process at a time to form them one after another.

(Problems to be Solved by the Invention) Although the conventional slush molding apparatus has the advantage of being able to automate the production of slush molded products with a relatively simple mechanism, it is difficult to process all of the molds on the conveyor in one process at a time. Since the process is sent to the next process one after another, if there is a difference in the time of each process, the time of each process must be adjusted to the time of the longest process. Therefore, in each process except the process that requires the longest time, each mold This method has disadvantages in that there is a waiting time and the productivity for the mold surface is extremely low.

In addition, as a means to shorten the molding cycle in this case, a method has been adopted in which each process that requires a long time is divided and distributed to a considerable number of stations that take equal time.
In this case, the device becomes long and a large number of molds are required.

In addition, when molding two or more types of molds with different molding conditions are simultaneously installed in one molding machine, the optimal molding conditions should be given to each mold, but the above-mentioned Due to process time constraints, molding had to be performed under similar conditions, resulting in defects in molded products due to overheating or overcooling.

The present invention addresses such drawbacks of the prior art and maximizes the productivity for each mold surface, resulting in the same productivity as before with a minimum number of mold surfaces, and two types of molding conditions under different molding conditions. Compact slush molding that provides optimal molding conditions for each mold and maintains an appropriate molding cycle even when molding the above types of molds is installed simultaneously in one molding machine. The purpose is to provide a device.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the inventor of the present application analyzed and researched each process of slush molding, and found that in slush molding, the time required for preheating the mold is generally the longest. It has been discovered that the time required for the following steps, namely the casting step, curing heating step, cooling step, and demolding step, can be made shorter than that. By keeping the preheating process, which is the first process of molding, longer than any other process, and moving each feeding device independently of each other for the following process times, the following processes can be performed without causing the mold to stagnate. , it is possible to create a situation where the process proceeds sequentially to the previous process. That is, the time of each process is not subject to equal restrictions on the time, and the process can be immediately moved to the next process when the process set under the optimum conditions for each mold is completed.

The feature of the present invention, which was completed based on this idea, is that the slush molding device is equipped with at least preheating, casting, curing heating, cooling, and molded product removal stations, and a conveyor that transports the mold between the stations. There is a standby station in front of the heating station, so that molds can be immediately sent to the preheating station.
The slush molding apparatus has a conveyor that has the function of conveying each mold individually, station by station.

By configuring the slush molding equipment as described above and operating the conveyors between each station independently, molding can be performed under the optimal molding conditions specific to each mold, and there is no waiting time between processes. In order to avoid this, the production efficiency of molds can be improved, and a standby station is installed to transport molds that have completed the final demolding process at high speed and wait at this standby station, so that the previous mold can be used as a spare. After finishing the heating process and moving to the next process, the next mold can start the preheating process without delay, and each process can proceed without waste and without stagnation.

This conveys the molds to the return conveyor.

The operation of the slush molding apparatus of this embodiment will be explained below by following each step of slush molding.

Initially, the slush molding apparatus of this embodiment starts molding from a state in which there are no molds at all in the lower stage and molds with an arbitrary number of surfaces are present in the standby station in the upper stage.

As the first step, the waiting station (8
) is lowered, the rotation shaft (12) of the mold (90) is released from the notch (47) of the stopper (48), and the travel rail (73) is lowered.
) on which the mold can freely roll and move.

Then, the electric motor (81) of the return conveyor (59) is activated to move the handling device (80) directly above the mold.

Next, the cylinder (76) is extended to lower the carrier (78), and the mold (90) is inserted from above using the notch (77).
The rotating shaft (12) is sandwiched between the two.

Thereafter, the electric motor (81) is started again to move the handling device (80), move the mold (90), and drive pulley (
73) Push and move the upper part to lift the mold onto the lift conveyor (57) (83), start the lift conveyor (57), and move the mold to the lower waiting station (9).

Then, the mold detection device installed in the preheating station (1) detects the presence or absence of a mold in the preheating station (1), and if the mold is present in the preheating station, the mold is placed in a standby station. Wait at step (9). When it is confirmed by the detection device that there is no mold in the preheating station (1), the slider (71) of the tact feed conveyor (50) is moved directly below the mold using the signal as a trigger, and the cylinder ( 72), the rotating shaft (12) of the mold (90) is held from below by the claw (68) of the slider (71), and the electric motor (6
3) is rotated to push and roll the mold (90) on the running rail (59), and the movable rail (29) of the mold rotating device (17) of the preheating station (1) is continuous with the running rail (59). After moving the mold (90), the cylinder (72) is retracted and the slider (71) is lowered to
) and move the slider towards the waiting station again.

At this time, the lift conveyor (57) and the return conveyor (59) repeat the same operations as before to transfer the mold to the standby station (9) and wait there.

Now, the mold (90) transported into the preheating station (1) in the previous step is moved to the mold rotating device (17).
Extend the cylinder (35) and push out the pin (22), and insert the pin (22) into the hole (14) of the handle plate (15) on both sides.
22) is inserted and fixed to the movable rail (29).

Then, while rotating the prime mover (19) of the rotating device (17), hot air is injected from the hot air injection nozzle or small hole (16) to heat the mold.

Then, after heating to a certain temperature by heating for a certain period of time preset by a timer or by measuring the temperature moment by moment with a thermometer, hot air is jetted from the nozzle or small hole (16) and the mold (90 ) is stopped, and the pin (32) of the mold rotating device (17) is removed from the hole (14) of the handle plate (15) to be free.

Then, the next step is the first casting station (2)
If there is a mold in the first casting station (2) of the next process, the mold remains in the preheating station (1) and the mold is transferred to the first casting station. If it is detected that there is no mold, the tact feed conveyor (51) is operated in the same way as the previous tact feed conveyor (50), and the mold is transported into the first casting station (2). .

The tact conveyor (51) (52) (53) (
54) It is most preferable to control (55) by confirming and detecting the presence or absence of the mold before transporting it, as described above, but in reality, as mentioned earlier, the time for each process is usually determined by preheating. Since the time is the longest, there is almost no mold in the next step at the end of each step, and each step progresses without a hitch.

Therefore, the time required for each step is all set by a timer, and in certain cases, a device for detecting the presence of a mold at each station may not be necessary.

In addition, when installing a wide variety of molds into the slush molding apparatus of this embodiment, the following steps can be performed by intentionally setting the molds to remain in the preheating station (1) for a long time. It can be made to proceed smoothly.

Next, the subsequent steps will be explained. As mentioned above, while the mold (90) is being conveyed from the preheating station (1) to the first casting station (2), it is detected that the mold is not present in the preheating station (1). , the tact feed conveyor (50) operates in the same way as the previous time, and sequentially transfers the molds in the standby station (9) to the preheating station (1).
).

Now, the mold transported into the first casting station is
A post-casting process coupled to a mold rotation device (17) takes place. To explain the casting process step by step, the reservoir tank lifting device (38) is operated and the bed (40
The reservoir tank (36) placed on the tank (36) is lifted up, and the openings are aligned with the mold, which is held in an attitude with the opening facing downward, and the openings are aligned with each other and the reservoir tank (36) is joined together by a joining device (not shown).

After that, the reservoir tank lifting device (38) is lowered, and the bed (
40) After stopping the mold and reservoir tank (36)
The slush raw material is put into the mold, and a semi-molten skin is attached to the molding surface.The mold is then rotated forward and reverse while still being joined together, and the mold is connected again to the reservoir tank (3) on the upper side.
6) is held in the lower position, and then the bed (4) is raised to hold the lower side of the reservoir tank (36), and the coupling device (not shown) is released to separate the reservoir tank (36) and the mold. Separate and place the reservoir tank (36) on the bed (40)
The first casting station process is completed by lowering the lift (40) and returning it to the original position to stop the reservoir tank (36).

When the first casting process is completed, the next process, the first casting process, is completed.
The first casting station (2) is conditioned on the fact that there is no mold in the cure heating station (3).
The mold (90) is transported into the first cure heating station (3) by a tact conveyor (52) between the mold and the first cure heating station (3), and the semi-molten skin attached to the mold (90) is removed. Cure.

In the same manner, the molds are sequentially transported to the second casting station (4) and the second cure heating station (5) to carry out the casting process and heating process, respectively, to form the solid skin formed in the previous process. Form a foam layer on the back. After these processes are completed, the cooling station (6) for the next process
When a signal indicating that there is no mold exists, the tact feed conveyor (56) is activated to convey the mold to the cooling station (6), and while the mold is rotating for a certain period of time, it is cooled from the shower nozzle (42). Water is injected into the mold for a certain period of time to cool it, and then air is blown from an air injection nozzle to drain water from the mold and the skin. After the cooling process is completed, the mold is removed from the cooling station (6) by the tact conveyor (56), triggered by the absence of the mold at the take-out station (7), which is the next process, or by an operator's operation. Move to take-out station (7). At the take-out station (7), the worker is kept in a position facing the worker so that the skin can be easily removed from the mold. Retrieval station (7
) is transferred to the lift (84) of the lift conveyor (58) waiting just below the take-out station (7).
The mold carrier (10) of the mold is scooped up from below and conveyed to the upper stage, and then transferred to the conveyor (59).
is conveyed to the standby station (8) and stands by.

Note that the conveyance speed of the conveyor (59) at this time can be set to a considerably high speed since it is not related to the molding process.

In this way, one mold completes a series of slush molding steps, and then the slush molding skin is automatically molded by repeating the inter-process cycle in sequence.

(Effects) The slush molding apparatus of the present invention focuses on the fact that there are differences in the time required for each step of the sludge uni method or for each mold.
．． Traditionally it was continuous. The function of the feed conveyor that sends the molds between each station is divided into individual parts, and the molds are sent to the next station only by the relationship between one station and the next station, regardless of other parts. By configuring the mold as shown in FIG. By transporting the molds at high speed in areas other than the necessary steps, the overall number of molds per unit time of each mold can be greatly increased.

In conventional slush molding equipment, when production demand changes and the number of molds installed and operated in the equipment decreases, the number of molds per unit time decreases in proportion to the decreased number of molds, reducing wasted time. Although this occurrence was unavoidable, the slush molding apparatus of the present invention has the advantage of being able to always maintain a constant number of molds per unit time even if the number of mold faces changes.

The slush molding device of the present invention can set optimal conditions individually for molds with different molding conditions.
It has the effect of preventing quality deterioration due to overheating and overcooling of the epidermis, and contributing to reductions in raw materials and energy consumption.

Furthermore, since the slush molding equipment of the present invention has a higher operating rate for each mold than conventional equipment, the number of molds held can be reduced compared to conventional equipment with the same production capacity, and the equipment can also be made smaller. It has the advantage of being able to

Further, when the slush molding apparatus of the present invention is implemented in the form of the previous embodiment, the molds are only mounted on the rails in the lower tact feeding conveyor section and the upper conveyor section, and are not connected equally. Since there is no need for IJ, it is easy to change molds due to changes in production plans, and the equipment can be operated without having to go through IJ.

Also, if the number of molds is within the number of waiting stations,
Can be loaded and unloaded freely.
