Description

  The present invention relates to a pile device, and more particularly, to an improvement of a pile device that stacks a plurality of stacked bodies, which are long plate-like bodies, in a stacked state.

  In recent years, a bumper removed from a vehicle is crushed by a crusher when it is reused as a resource. However, before being crushed by a crusher, in many cases, the bumper has a complicated three-dimensional shape.

  On the other hand, the bumper that is removed from the vehicle is formed while having a material display with different materials depending on the so-called vehicle manufacturer and production time. Become.

  Therefore, the bumper removed from this vehicle is rolled with a rolling mill, and the volume display is reduced to a plate shape without losing the material display. At the same time, when there are a large number of bumpers to be volume-reduced in a substantially plate shape, it is necessary to collect them.

  For example, the piling device disclosed in Patent Document 1 is a device that stacks and stacks plate materials that are stacked, and in particular, when a plate material is further stacked on a previous plate material, the surface of the previous plate material is damaged. Consideration is not given.

  Therefore, when using this piling apparatus, it is possible to bundle a large number of stacked bodies, which are bumpers that have been rolled by a rolling mill and reduced in volume into a substantially plate shape, in a stacked state. It is possible to improve the efficiency in transporting the stacked body that is a long plate-like body by using a truck.

Japanese Patent Laid-Open No. 2000-255865 (abstract, refer to paragraphs 0006 to 0008 and FIGS. 1 to 4 in the specification)

  However, in the proposal disclosed in Patent Document 1 described above, there is basically no problem in that the stacked bodies that are a large number of long plate-like bodies can be gathered into a stacked state, Considering the actual situation, there is a slight defect.

  That is, a bumper that has been rolled by a rolling mill that is a stacked body and volume-reduced in a plate shape is crushed by a crusher after crushing, and when stacked, There is no need to worry about the appearance of the scratching phenomenon.

  In view of this, in the proposal disclosed in Patent Document 1, consideration is given to avoiding the occurrence of a scratch phenomenon in the previous stacked body, that is, the subsequent stacked body is directly connected to the previous stacked body. In order to avoid stacking on the stack, a receiving device is provided to put a breath, so when the stack is a bumper that has been rolled by the above rolling mill and reduced in volume to a plate shape. The equipment of this receiving device is completely useless.

  A bumper that has been rolled by a rolling mill as a stack and reduced in volume to a plate shape has various lengths. Therefore, if the above receiving device is provided, the configuration is complicated. There is a bug to make.

  The present invention was devised in view of such a current situation, and the object of the present invention is to reduce the volume into a substantially plate shape by rolling with a large number of long stacked bodies, for example, a rolling mill. It is another object of the present invention to provide a piling apparatus that is optimal for expecting an improvement in versatility by making it possible to collect a large number of bumpers in a stacked state.

In order to achieve the above-described object, the problem-solving means of the present invention allows the accommodation of the stacked body descending from the opening formed at the upper end and climbs from the base end to the tip at both upper end portions of the opening. A receiving means provided with a rail that becomes a slope ,
Guide means provided on the rail and moving along the rail ,
It said guide means in a direction down the upward slope at eliminating backward Then both the external force acting in a direction to climb the uphill external force acting from the object to be stacking member coming is moved towards the said guide means in the transport means It is characterized by moving forward .

Therefore, in the present invention, the guide means retreats along the rails provided at the upper ends on both sides of the opening in the receiving means under the action of the external force from the stacked body moving above the receiving means . , The upward movement of the receiving means of the stacked body becomes possible, and when the base end of the stacked body descends into the receiving means after the dredging , the leading end of the stacked body and the guide means The tip of the stacked body is also lowered into the receiving means, and the stacked body is accommodated in the receiving means as a whole.

  Then, when the external force action is canceled from the state where the guide means is retreated by climbing the climbing gradient at the upper end portion of the receiving means, the guide means moves forward to descend the climbing gradient, and the tip of the next stacked object is It will be ready to abut or carry.

  At this time, the guide means does not have a driving means, and descends at the upper end portion of the receiving means with the inclination and the own weight of the climbing gradient. It will not descend and will not produce an impact or impact sound.

  In addition, by repeating so-called raising and lowering of the above-described guide means, it is possible to accommodate a large number of stacked bodies in the receiving means in a stacked state and collect them.

It is a schematic longitudinal cross-sectional view shown in one operating state of the pyring apparatus by this invention. FIG. 2 is a schematic plan view showing the pile device of FIG. 1. It is a schematic longitudinal cross-sectional view which shows the operation state of the pyring apparatus following FIG. It is a figure which shows the operating state of the pyring apparatus following FIG. 3 similarly to FIG. It is a figure which shows the operating state of the pyring apparatus following FIG. 4 similarly to FIG. It is a figure which shows the operating state of the pyring apparatus following FIG. 5 similarly to FIG.

In the following, the present invention will be described based on the illustrated embodiment. A piling device according to the present invention collects a long plate-like body, which is a large number of stacked bodies, in a stacked state, and is shown in FIGS. As shown in FIG. 2, the receiving means 1 and the guide means 2 are provided, and the conveying means 3 is further provided.
And the receiving means 1 accept | permits accommodation of the to-be-stacked body W descend | falling from the opening part formed in the upper end, and the rail 11 which becomes a climbing gradient from a base end to a front-end | tip is provided in the both-side upper end part of this opening part. .
Further, the guide means 2 is provided on the rail 11 and moves along the rail 11.

  In the illustrated embodiment, a long plate-like body that is a stacked body W (see FIG. 1) gathered by the piling apparatus is not shown in detail, but is a rolling mill that is removed from the vehicle and is a rolling means in advance. Bumpers that have been rolled and reduced in volume to a plate shape.

  Further, a large number of bumpers subjected to volume reduction processing, which are collected in a stacked state by this piling device, are also transferred to a specialized factory or the like where the crusher is installed by transferring the receiving means 1 as it is, although not shown. In addition, a large number of sheets are compressed in the receiving means 1 by an appropriate compressing means, and are bundled together with a band or the like under the compressed state, taken out from the receiving means 1 and used for transportation by truck.

  The description will be made under such a premise. First, the receiving means 1 accommodates a large number of stacked bodies W in a stacked state, and as long as the receiving means 1 can be arbitrarily configured, Is formed into a frame structure having a predetermined mechanical strength so that the weight can be reduced as much as possible.

  This is because, as described above, since the bumper removed from the vehicle has a complicated three-dimensional shape as it is, when it is transported as it is to a specialized factory where a crusher is installed, the transportation efficiency is reduced. Make it worse.

  Therefore, as described above, it is proposed that the bumper removed from the vehicle is rolled with a rolling mill in advance to reduce the volume to a substantially plate shape. This specialized factory also installs the rolling mill for this volume reduction processing. If it is put into practice, there is a concern that the transportation efficiency will decline.

  Therefore, it is best to reduce the volume of the bumper removed from the vehicle to a plate shape, so that the so-called site where the bumper is removed from the vehicle is optimal, but considering the actual situation of this type of site, a rolling mill is installed at each site. The feasibility of making proposals to reduce bumper volume is low.

  Based on the above, the rolling machine that reduces the volume of the bumper that has been removed from the vehicle to a substantially plate shape is the same, but the pile device of the present invention collects the bumper that has been rolled by the rolling machine and reduced to a substantially plate shape. In addition, it is preferable that the vehicle can be moved by being loaded together with the conveying means 3 on a loading platform in a vehicle having a driving structure such as a truck or a loading platform in a vehicle having a towing structure such as a trailer. It is preferable that 1 is formed in a frame structure to reduce the weight.

  Next, the receiving means 1 accommodates a bumper that has been rolled by a rolling mill and reduced in volume to a substantially plate shape. As described above, the bumper to be removed from the vehicle is the same for each vehicle manufacturer. Even if it is a maker, since it is formed in arbitrary three-dimensional shapes for every vehicle model, when this is rolled and volume-reduced processing to a substantially plate shape, length will vary.

  That is, the volume-reduced bumper accommodated in the receiving means 1 has various lengths. Therefore, if the dimension in the length direction of the receiving means 1 is regulated, there is a high possibility that the bumper will be defective. .

  Therefore, the receiving means 1 shown in the figure is formed in a side groove shape having no barrier in the length direction, that is, in such a manner that the cross-sectional shape in the short side direction is formed in a square U shape, and the length varies. In addition to allowing accommodation of the stacked body W, the stacked body W accommodated in a stacked state is taken into consideration so as not to protrude out of the receiving means 1.

  By the way, since the receiving means 1 is formed in a frame structure, it is easy to visually recognize from the outside of the state of accommodation of the stack W with respect to the receiving means 1 and a large number of sheets accommodated in the receiving means 1 This is advantageous in terms of facilitating the band hanging work when bundling the stacked objects W and the sling work when lifting with a crane.

  As for the width dimension in the short direction of the receiving means 1, from the viewpoint of collecting a large number of stacked bodies W in a stacked state, as shown in FIG. 2 is preferably set to be larger than the width dimension in the vertical direction in FIG. 2, thereby causing a problem that the stacked body W conveyed from the conveying means 3 falls out of the receiving means 1. It is no longer expressed.

  Further, the length dimension in the longitudinal direction of the receiving means 1 is set to be larger than the length of the bumper subjected to volume reduction processing, that is, the length corresponding to the expected length of the bumper. In the case where the length is set to exceed the assumed length, the above-described barrier may be provided in consideration of so-called transportability.

  And in the conveyance means 3, when mounting the to-be-stacked body W and transferring this, it is preferable to have a width dimension which is sufficient in order not to make the to-be-stacked body W interfere with a peripheral part. .

  On the other hand, the receiving means 1 takes the following considerations in order to make the guide means 2 described later function.

  That is, first, the guide means 2 is mounted on the upper end portion of the receiving means 1 so as to straddle the upper end opening of the receiving means 1 (see FIG. 2). From this state, the guide means 2 is indicated by an arrow in FIG. As shown, it is movable at the upper end of the receiving means 1 from the proximal end, which is the left end in FIG. 2, toward the distal end, which is the right end in FIG.

  The guide means 2 is also located at the upper end of the receiving means 1 and is movable from the distal end toward the proximal end, that is, advanceable.

  Further, the guide means 2 has a main body portion 21 that abuts the tip of the stacked body W (see FIG. 1) and carries (see FIG. 4) and is connected to the main body portion 21. It has a plurality of rollers 22 as a mechanism.

  As a result, the main body portion 21 may be basically formed in an arbitrary shape, as long as it is sufficient to abut and carry the tip of the stacked body W. The flat table 21a is formed in a shape having a partition 21b.

At this time, in this main body portion 21, the partition 21 b is provided in the center of the moving direction which is the left-right direction in FIGS. 1 and 2 of the flat table 21 a and is erected in a direction crossing this moving direction. The so-called front part or rear part, which is the left and right parts in FIG. 1 and FIG. 2, of the flat table 21a defined by the partition 21b can be used for supporting the stack W.

  Such a configuration is advantageous in that it is not necessary to consider so-called front and rear when the guide means 2 is mounted on the upper end of the receiving means 1, and it is advantageous in that durability is also improved.

  On the other hand, the plurality of rollers 22 as the traveling mechanism is sufficient as long as it enables the movement of the main body 21 as a result. Therefore, it is sufficient if the rollers 22 are held rotatably with respect to the main body 21 with an arbitrary structure. As shown in the figure, it is pivotally supported by a bracket 21c connected to the lower surface of the flat table 21a.

  Incidentally, the constituent material of the roller 22 may be arbitrarily selected as long as it exhibits a predetermined rolling function. For example, from the viewpoint of weight reduction, noise prevention, and cost, It is good to form with a synthetic resin material.

  As for the state of arrangement of the rollers 22, in order to bring the front end of the stacked body W into contact with and support the main body 21 in a stable state, it is arranged on the so-called front and rear side of the main body 21. It is preferable to be provided, and so long as there is no special purpose, it is good to arrange so-called right and left.

  Further, the stopper of the roller 22, that is, the stopper of the guide means 2 is the four corners 1 a (see FIG. 2) in plan view of the receiving means 1, and the roller 22 is brought into contact with the four corners 1 a, Derailment of the guide means 2 from the upper end of the receiving means 1 is prevented.

  On the other hand, the receiving means 1 for mounting the guide means 2 has the rails 11 at the upper ends of both side portions forming the upper end opening that the guide means 2 spans. However, while allowing the roller 22 to be placed in the guide means 2 described above, the guide means 2 has an inclination that is an upward gradient from the base end that is the left end in FIG. 1 to the tip that is the right end in FIG.

  At this time, this inclination is such that the angle θ (see FIG. 1) with respect to the horizontal is 2 to 5 degrees, and when the guide means 2 climbs the climbing slope that is inclined, it is assumed that it can climb without difficulty.

  As described above, when the inclination of the rail 11 formed on the upper end portion of the receiving means 1 is 2 to 5 degrees, the guide means 2 can climb the climbing gradient with a slight external force action, and the external force action. When the guide means 2 goes down this inclined climbing slope, it is possible to go down at a low speed, and when the angle θ is, for example, 10 degrees or more, it goes down at a high speed. In comparison, the occurrence of impact and impact sound can be avoided.

  Incidentally, the above-mentioned rail 11 can be easily revealed by forming the upper end portion forming the above-mentioned upper end opening with, for example, an angle material having a L-shaped cross section as a mold material. As long as it is made to appear, a free structure other than the above-described angle material may be selected.

However, when the upper end portion forming the upper end opening is formed of an angle material as a mold material because of having the rail 11, the mechanical strength against so-called bending can be increased, and the upper end portion of the receiving means 1 can be increased. This is advantageous in that it can prevent mischievous deformation, maintain the posture of the rail 11 and ensure the movement of the guide means 2.

  And when using the angle material which is a type | mold material in order to form the rail 11, the hook along the rail 11 can be formed together, and it is derailed from the rail 11 of the guide means 2 by formation of this hook. This is advantageous in that it can be effectively prevented.

  By the way, the bumper whose tip is brought into contact with the guide means 2 or carried and reduced in volume, which is the loaded object W, is transported to the pile device side by an arbitrary means. It is conveyed by the conveying means 3.

  That is, in view of the situation in which this piling apparatus is used, in many cases, this bumping apparatus is used after the bumper removed from the vehicle is rolled with a rolling mill and subjected to volume reduction processing in a substantially plate shape.

  At this time, the bumper discharged from the rolling mill and reduced in volume to a plate shape is not delivered to the piling apparatus as it is, but once delivered to the conveying means 3 and placed in a so-called stable state. It will be normal to be handed over to this piling device.

  That is, since the tip of the bumper that has been reduced in volume to a plate shape and is discharged from the rolling mill is usually displaced so as to be violated in an arbitrary direction, the displacing tip is exposed to the main body of the guide means 2. Accordingly, it is difficult to bring the bumper 21 into contact with or accurately carry the bumper 21. Therefore, the bumper after volume reduction discharged from the rolling mill is normally delivered to the conveying means 3 once.

  Therefore, even in the illustrated pile device, the bumper that has been subjected to volume reduction processing as the stacked body W is infinitely moved by the driving unit 3, that is, not shown in detail in the drawing. The belt conveyor having the belt 31 (see FIG. 2) is transported to the piling apparatus side.

  By the way, in this piling apparatus, it is only necessary to supply the reduced volume bumper as the stacked body W as a result. Therefore, even if the reduced volume bumper is supplied by an operator, that is, manually. Of course it is good.

  In particular, when this piling apparatus is set at a location away from the rolling mill, the bumper reduced in volume by the rolling mill is manually piled without using the conveying means 3 including the belt conveyor. It may be delivered to the device.

  On the other hand, when the belt conveyor which is the conveying means 3 is used, this belt conveyor can receive the bumper which has been volume-reduced by the rolling mill and can convey it directly to the piling apparatus.

  At this time, the front end of the belt conveyor that is the conveying means 3 is arranged so that the tip of the bumper subjected to volume reduction as the stacked body W conveyed by the belt conveyor does not interfere with mischief. Needless to say, it is important to position the stacked body W above the upper end position of the receiving means 1 in order to ensure that the tip of the stacked body W is brought into contact with the guide means 2.

  And as long as the front-end | tip of a belt conveyor is positioned above the upper end position in the receiving means 1, the base end used as the rolling mill side of a belt conveyor may be below a front-end | tip, and conversely, it is positioned higher. Also good.

  Incidentally, when the front end position of the belt conveyor is positioned higher than the upper end position of the receiving means 1, it is advantageous in that the upper end position of the receiving means 1 can be raised and the receiving means 1 can be raised.

  In addition, it is preferable that the belt conveyor which is the conveyance means 3 preferably has a rib on the surface of the infinite belt 31 to increase the sliding resistance with respect to the stacked body W1, thereby improving the conveyance effect.

  In the pile device of the present invention formed as described above, a large number of long plate-like bodies, which are the stacked bodies W, are collected in a stacked state as follows.

  That is, first, the stacked body W as a volume-reduced bumper conveyed from the conveying means 3 contacts the main body 21 of the guide means 2 whose tip is mounted on the upper end of the receiving means 1. In this state, since the transport of the stacked body W by the transport means 3 is continued, the guide means 2 is inclined so as to have an upward slope formed at the upper end portion of the receiving means 1 by the action of an external force. 11 is moved backward (see FIG. 3).

  Then, as shown in FIG. 4, when the backward movement of the guide means 2 is continued and the rear end of the stacked body W comes away from the front end of the transport means 3, as shown in FIG. The rear end of W falls to the inside of the receiving means 1, and at this time, the leading end of the stacked body W is separated from the guide means 2 and falls to the inside of the receiving means 1. Be contained.

  On the other hand, since the external force that has been applied to the guide means 2 mounted on the upper end portion of the receiving means 1 is eliminated, the guide means 2 has an upward slope as shown by an arrow in FIG. At this time, the guide means 2 does not have a drive source and descends by its own weight. Therefore, the weight of the guide means 2 is lowered at a high speed. Without generating a shock or impact sound compared to the case where the vehicle descends at a high speed.

  Then, as shown in FIG. 6, the guide means 2 lowered to the base end of the sloped rail 11 waits for the contact of the leading end of the next stacked body W conveyed by the conveying means 3, and after In the state shown in FIG. 1, the above-described operation is repeated, and a plurality of volume-reduced bumpers, which are the stacked bodies W, are accommodated in the receiving means 1 in a stacked state.

  In the above description, it has been described that the stack W to be collected by the pile device of the present invention is composed of a bumper that is removed from the vehicle, rolled by a rolling mill, and reduced in volume to a substantially plate shape. From the intended point of view, the stack W to be gathered by the piling apparatus is not limited to the bumper described above, but may be other long plate-like bodies, and the effects in this case are not different.

  In the above description, the receiving means 1 constituting the piling apparatus according to the present invention is formed in a frame structure and placed on the loading platform of a truck or a trailer. However, the receiving means 1 functions. Then, the receiving means 1 may be composed of a loading platform itself in a truck or a trailer. In this case, the guide means 2 may be mounted in a state where it cannot be separated from the receiving means 1. It may be transported separately from the means 1 and mounted when used.

  Further, in the above description, the traveling mechanism that is connected to the main body portion 21 in the guide means 2 and allows the movement of the main body portion 21 along the rails 11 includes the roller 22. As long as movement is possible, instead of this, the surface of the rail 11 is subjected to a smooth surface treatment by using Teflon (registered trademark) or the like, and the traveling mechanism has a projection whose surface is processed by Teflon (registered trademark), or It may be a flat surface.

  Furthermore, in the above description, the example of the case where the piled body W which is a long plate-like body is put together in a stacked state is described as an example of the present invention. Of course, even if the body W is not a long plate-like body but a short plate-like body, it can be used, and the action and effects in that case are not different.

  It is suitable for stacking stacked objects, which are a large number of long plate-like bodies, in a laminated state.
