Description

Parallel wet pulp molding machine {Pulp molding machine}

The present invention relates to a parallel wet pulp molding apparatus, and more particularly, comprising a plurality of forming means and a plurality of adsorption means for reciprocating the upper portion of the conveyor means to form a primary pulp molding in any one of the plurality of forming means. During the forming time, the parallel wet pulp molding is carried out to transfer the priming pulp formed by the adsorption means to the conveyor means to shorten the suction time and transfer time of the priming pulp molding to maximize the production per unit time to enhance the product competitiveness. Relates to a device.

In general, pulp moldings are manufactured using pulp as raw materials, and are mainly used in various fields such as shock-absorbing packaging materials and cases, and have been widely used because of their useful value.

In addition, the method for producing the pulp molding, the pulp solution is formed by mixing the de-melting pulp and water in an appropriate ratio, such as 1: 9, and then sucked it into the mold mold, the pulp raw material of the pulp solution is adsorbed and fine The pulp material or water is sucked and recovered into a separate storage tank, and the pulp molding is completed when the primary pulp molding adsorbed to the mold is dried by a drying furnace or a separate heat source.

In addition, the apparatus for manufacturing pulp molding as described above is largely divided into a dry pulp mold molding apparatus and a wet pulp molding apparatus, the former dry pulp mold molding apparatus is a high-precision packaging such as a casing to wrap a cell phone in a box, etc. It is used to manufacture a packaging material and the manufacturing cost is expensive, and the latter wet pulp molding machine is used to manufacture a low-precision packaging material such as an egg plate which seats a large number of eggs and the manufacturing cost is low.

Here, precision refers to the surface roughness of the pulp molding, and the pulp molding manufactured with high precision has a smooth surface to prevent damage to the surface of the electronic product when packaging expensive electronic products, and pulp manufactured with low precision. Molded products are intended to reduce the manufacturing cost of mass production for the purpose of packaging products regardless of surface roughness.

On the other hand, the latter pulp mold forming apparatus includes a molding unit for forming a primary pulp molding in a pulp solution, a conveyor unit provided on one side of the molding unit and transferring the primary pulp molding formed in the molding unit, and one side of the conveyor means. It is composed of a drying furnace for drying the moisture contained in the primary pulp moldings provided to the conveyor means.

The molding unit may be installed at a storage tank for storing a pulp solution, a lower mold to be freshwater from the storage tank, and a lower mold installed at a lower end of the lower mold, and provided at an upper portion of the upper mold and the cylinder for elevating the lower mold. It consists of an upper mold.

Referring to the operating state of the conventional wet pulp molding apparatus configured as described above, first, the pulp material is sucked to the surface of the lower mold by sucking the pulp solution in the state in which the lower mold of the molding part is in the fresh water in the storage tank to form the primary pulp molding. do.

In addition, the lower mold on which the primary pulp molding is adsorbed is raised by the upward operation of the cylinder, and is mutually engaged with the upper mold provided at the upper portion.

And when the upper and lower molds are engaged, the suction force is blocked in the lower mold and the suction force is generated in the upper mold so that the primary pulp molding is turned over from the lower mold to the upper mold.

Then, the upper and lower molds are separated and the lower molds are lowered and immersed in the storage tank, and the upper molds are reversed and positioned at the upper portion of the conveyor means, and the upper molds block the suction force so that the primary pulp molding is dropped into the conveyor means.

Thereafter, the primary pulp molding is transferred to the drying furnace along the conveyor means, and the moisture contained in the primary pulp molding is dried by the drying furnace to complete the pulp molding.

However, in the above case, the upper mold has a shorter transfer time for reciprocating the lower mold and the conveyor means than the time at which the lower mold forms the primary pulp molding, so that the upper mold during the lower mold forms the primary pulp molding. Operation is stopped, there is a problem that the output per unit time is low.

In order to solve the above problems, Korean Patent No. 10-419294 (name: valve device for rotary pulp mold forming machine), the pulp mold forming apparatus is rotated in one direction by the driving means, the upper and lower surfaces of the rotating body The mold is coupled to the upper side, and the upper side of the mold is coupled to the transfer mold driven up, down, left and right by a transfer device.

In the operation state of the pulp mold forming apparatus, the mold mounted on the lower surface of the rotating body forms the first pulp molding in the fresh water in the storage tank for storing the pulp solution, and is then rotated in one direction by the rotating body. When positioned on the upper surface, the mold located on the upper surface is transferred to the lower surface.

Then, the transfer mold is transferred to the mold die transferred to the upper surface to be engaged with the mold on the upper surface, and then the primary pulp molding is transferred to the transfer mold by the operation as described above.

In addition, the matched transfer mold and the upper surface mold is separated, the transfer mold is raised and conveyed to the right to take over the primary pulp molding to the conveyor means.

In addition, the upper mold is rotated to the lower surface by the rotation of the rotating body and the lower mold is rotated to the upper surface to take over the primary pulp molding to the transfer mold by the method described above.

Therefore, as the molds mounted on the upper and lower surfaces of the rotating body are repeatedly rotated in one direction rotation of the rotating body, it is intended to shorten the time for forming the primary pulp molding in the storage tank.

However, in the case of the rotary type, that is, the rotary type, when the mold installed on the upper surface of the rotating body is rotated to the lower surface by one direction rotation of the rotating body, the tip point of the mold first obtained in the storage tank and the mold rotated on the lower surface are When the fresh water is completely immersed in the storage tank and subsequently rotated to the upper surface by the rotation of the rotor, the suction time of the pulp solution at the rear end point of the mold is different from each other, thereby forming a first pulp molding having an irregular thickness.

That is, the mold mounted on the rotating body sucks the pulp solution and is located on the upper surface while absorbing the primary pulp moldings formed thereby, and the suction force is blocked only when positioned on the upper surface to transfer the primary pulp molding to the transfer mold. In the mold, the pulp solution is sucked with suction force from the tip of the mold first received in the storage tank according to the one-way rotation of the rotating body while the suction force is continuously generated, and then the diving is completed by continuous rotation. The rear end, which is the symmetry point, is obtained last, and the pulp raw material adsorption thickness is different at the interval between the end and the end of the pulp solution suction time.

Therefore, in the case of the rotary pulp molding machine, there is a problem that the pulp molding product loses the reliability of the pulp molding by forming the first pulp molding having an irregular thickness due to the different time taken to suck the pulp solution from one mold by the rotation of the rotating body. .

In addition, the installation of the upper and lower molds on the one rotating body and also providing a vacuum pressure to the upper and lower molds, and the installation of the equipment is complicated by applying a system that blocks them, so that maintenance is difficult due to failures in the future. In addition, there was a problem that the maintenance cost is increased.

It is an object of the present invention to solve the above problems is composed of a plurality of forming means for forming the primary pulp molding and a plurality of adsorption means for transferring the primary pulp molding to the conveyor means while reciprocating the upper portion of the forming means. And the first pulp molding formed in the other forming means is transferred to the conveyor means by the suction means during the suction time for forming the first pulp molding in any one of the plurality of forming means. The purpose of the present invention is to provide a parallel wet pulp molding apparatus that maximizes the production per unit time by shortening the product competitiveness.

Another object according to the present invention is a wet pulp mold by forming a first pulp molding of a constant thickness as a constant suction force to the whole of the lower mold as the lower mold to be stored in the storage tank is vertically elevated while maintaining the horizontal state Another object of the present invention is to provide a parallel wet pulp molding machine for improving the product reliability of the pulp molding according to the molding machine.

It is a general technical idea that the upper molds 164 and 174 are formed in a symmetrical shape and a plurality of through holes are formed to facilitate the adsorption of the pulp solution and the primary pulp molding by vacuum pressure.

The operation state of the parallel wet pulp molding apparatus configured as described above is as follows.

3A to 3C, for convenience of description, the first forming means 120 formed on the left side with respect to the conveyor means 20 installed in the center of the frame 110 is referred to as a first zone I, and on the right side. The installed second forming means 130 is called the third zone (III), and the zone in which the conveyor means 20 is located is called the second zone (II).

First Zone I-See FIGS. 3A and 3B.

The first lower mold 124 dehydrated in the first storage tank 122 of the first forming means 120 with the first adsorption means 160 positioned on the first forming means 120 is deposited. The pulp solution is sucked by pneumatic pressure, and among these, pulp material in the form of dry matter is adsorbed on the mold mold to form a primary pulp molding on the surface of the first lower mold 124.

In addition, the first lower mold 124 is raised by the lifting operation of the first elevating means 126, and the rising height of the first lower mold 124 is the surface of the pulp solution fresh water in the first storage tank 122. It is desirable to make the excess.

In addition, the first upper mold 164 fixed to the end of the first rod 162a is lowered by the lowering operation of the first lifting cylinder 162 in the first adsorption means 160, so that the first lower mold 124 ) And the first upper mold 164 are engaged with each other. In this case, when the first lower mold 124 is raised, the first upper mold 164 is also lowered to form a mutually engaged state.

In addition, when the vacuum pressure transmitted to the first lower mold 124 is blocked in the mutually engaged state as described above, the suction force for sucking the primary pulp molding disappears, and the first upper mold 164 generates a vacuum pressure to The suction force is applied to the primary pulp molding by the vacuum pressure, and thus the primary pulp molding is adsorbed on the upper mold 154.

In this case, the primary pulp molding adsorbed to the first upper mold 164 simultaneously sucks the residual pulp molding and the moisture remaining in the primary pulp molding by the suction force of the first upper mold 164. Allow to shorten the drying time.

Thereafter, the first lower mold 124 is lowered, the first upper mold 164 is raised to return to the initial position, and the first pulp molding is transferred from the first lower mold 124 to the first upper mold 164. Perform the transported operating state.

On the other hand, the first lower mold 124 is a fresh water in the pulp solution of the first storage tank 122 to suck the pulp solution with the vacuum pressure opened to produce a primitive pulp molding, the primary pulp molding is adsorbed The first adsorption means 160 is moved to the right by the first cylinder 144 of the first transport means 140 and is located in the second zone II.

Second Zone (II)-See FIG. 3C.

In the state where the first adsorption means 160 is positioned above the conveyor means 20, the conveyor means 20 continuously moves a belt having a traveling direction toward the drying furnace 30.

In addition, the first upper cylinder 164 coupled to the end of the first rod 162a by lowering the first rod 162a at the lowering pressure of the first lifting cylinder 162 of the first adsorption means 160 is provided. Descends.

In this case, when the first upper mold 164 lowered to a predetermined depth cuts off the vacuum pressure to remove suction force for adsorbing the primary pulp molding, the primary pulp molding containing moisture is in the first upper mold 164. The free fall by its own weight is seated on the belt upper surface of the conveyor means (20).

In some cases, when the primary pulp molding is not dropped from the first upper mold 154 in a state in which the vacuum pressure is blocked, the primary pulp molding is forcibly removed from the first upper mold 164 by receiving air from the compressor. You may.

In addition, the primary pulp moldings seated on the belt upper surface of the conveyor means 20 enters the drying furnace 30 according to the guide of the belt, and the moisture contained in the primary pulp moldings is rolled by the drying furnace 30. The final pulp molding is formed.

Thereafter, the first upper mold 164 is returned to an initial state along the first rod 162a by the rising pressure of the first elevating cylinder 162 to the first zone (I) by the first transfer means 140. Move.

Here, the first upper mold 164 blocks the vacuum pressure while entering the second zone (II) without the lifting operation to shorten the transfer time of the primary pulp molding, so that the primary pulp molding is the conveyor means 20. It can also be seated in).

 On the other hand, when the first adsorption means 160 is located in the second zone (II), the second adsorption means 170 maintains the state located above the second forming means 130 in the third zone (III). .

At this time, in the second molding means 130, the first pulp molding material in which the pulp material of the pulp solution is adsorbed on the mold surface is formed on the second lower mold 134, which is the first pulp molding in the first zone (I). During the transfer time transferred to the conveyor means 20 of the second zone (II) after being turned over to the first upper mold 164 by mutual engagement of the first forming means 120 and the first upper mold 160 In the second forming means 130, the suction process of sucking the pulp solution to form the primary pulp molding is performed at the same time, thereby shortening the transfer time and the suction time.

The second lower mold 134 of the second forming means 130 is lifted by the second lifting means 136 and the second upper mold by the second lifting cylinder 172 of the second adsorption means 170. As the 174 is lowered and engaged with each other, the primary pulp moldings are turned over to the second upper mold 174 and then separated from each other, which is the first molding means 120 and the first forming means 120 in the above-described first zone (I). Since the operation relationship with the first adsorption means 160 is the same, a detailed description thereof will be omitted.

That is, in the second zone (II), the primary pulp molding adsorbed on the first upper mold 154 of the first adsorption means 160 is transferred to the conveyor means 20, and in the third zone (III), the second molding is carried out. The primary pulp molding formed on the second lower mold 134 of the means 130 forms a state of being adsorbed by the second upper mold 174 of the second adsorption means 170.

In addition, the first transfer means 140 is slid to the left, that is, the first position (i) to position the first adsorption means 160 in the first zone (I) and the second adsorption means 170 by the second transfer means 150. It is located in this second zone (II).

In addition, the first adsorption means 150 located in the first zone (I) adsorbs the primary pulp molding by the above-described operating state, and the second upper mold 174 located in the second zone (II) has a vacuum pressure. Blocking the primary pulp molding adsorbed to the second upper mold 174 is forced to fall through the free fall due to its own weight or air provided by the compressor (not shown) to be seated in the conveyor means (20).

In addition, the primary pulp molding seated on the conveyor means 20 is transferred to the drying furnace 30 through the conveyor means 20 to dry the moisture contained in the primary pulp molding to form a final pulp molding.

Here, the first and second transfer means 140, 150 is provided with a separate control device (not shown) to be paused when located in each zone, the control device is a timer for controlling the time, for example It is a general technical idea that a limit switch detecting a position by a sensor or a contact or a position detecting sensor using an infrared light is used.

In addition, in the above description, the operating state in which the first and second upper molds 164 and 174 of the first and second adsorption means 160 and 170 are elevated is described as a main point. The molds 164 and 174 are conveyed to the left and the right while being fixed to the first and second conveying plates 142 and 152 and the first and second forming means of the first and second forming means 120 and 130. 2 Lower molds 124 and 134 are formed to be elevated to the height to be engaged with the first and second upper molds 164 and 174, thereby reducing the engagement and transfer time, lowering the overall installation cost and maintenance costs It can also be configured to reduce.

Therefore, it is composed of a plurality of molding means and adsorption means, and interworked with each other repeatedly to reduce the transfer time and suction time due to the overlap of the suction time for the formation of the primary pulp molding and the transfer time transferred to the conveyor means to reduce the production per unit time It has the effect of strengthening the product competitiveness by maximizing.

In particular, during the time of forming the first pulp molding in the first zone and transferring it to the first adsorption means and transferring it to the second zone, in the third zone, the time for adsorbing the first pulp molding and the second molding means and the second adsorption means As the time for mutual engagement becomes longer, the moisture contained in the primary pulp molding is sucked by the suction force due to mutual coupling, thereby reducing the drying time of the primary pulp molding in the drying furnace.

That is, in this case, the suction force is generated in the lower mold as the pulp molding is taken over from one zone and transferred to the second zone, while the pulp molding is formed in another zone and the mutual engagement time of the upper and lower molds becomes longer. In the upper mold is to release the air to remove the moisture contained in the primary pulp molding there is an effect to shorten the drying time in the subsequent drying furnace.

 In addition, the first and second lower molds 124 and 134 of the first and second forming means 120 and 130 respectively installed in the first zone (I) and the second zone (II) have different shapes. By installing a mold, one device can produce pulp moldings of different shapes.

As such, a plurality of forming means for forming the primary pulp molding and an upper mold means for transferring the primary pulp molding to the conveyor means while reciprocating the upper portion of the forming means are used to transfer the primary pulp molding in any one of the plurality of molding means. The primary pulp molding formed on the other forming means during the suction time to be formed is transferred to the conveyor means by the upper mold means, thereby maximizing the production per unit time by shortening the suction time and the transfer time of the primary pulp molding product. It has the effect of strengthening.

In addition, as the lower mold to be stored in the storage tank is vertically elevated while maintaining the horizontal state, the pulp according to the wet pulp mold forming apparatus is formed by forming a first pulp molding having a constant thickness by generating burrs of a constant suction force into the entire lower mold. There is an effect to improve the product reliability of the molding.

In addition, the molding means is formed in the form of a mouth as compared to the conventional molding means according to the rotary structure of the device is simplified, as well as easy maintenance due to the failure of the device and also has the effect of reducing the cost of maintenance.
