Description

Description: TECHNICAL FIELD The present invention relates to a work processing machine using a forklift. Hereinafter, for convenience of explanation, a description will be given of an example of crushing and reducing the volume of an empty container for business use by a press.

BACKGROUND ART When consuming chemicals, kerosene, lubricating oils, edible oils, foods, paints, etc. in factories for production and production, 18-liter cans and
Commercial containers made of metal or synthetic resin, such as 20-liter cans or drums, are convenient and often used.

When such a commercial container is finished using chemicals or the like, it is piled up in a corner outside the factory or the like and discarded collectively.However, if the shape of the container remains, it requires a large space to leave before disposal. In addition, in the case of disposal, a large number of vehicles cannot be mounted on the carrier of the transport vehicle, and many vehicles are required, resulting in high disposal costs.

Therefore, as shown in FIG. 11, a hydraulic pump, a hydraulic tank, a hydraulic valve, an electric switchboard, etc. are built in the base 50, while the mounting plate 51 is
, A hydraulic cylinder 53 is attached to the mounting plate 51, a crushing plate 55 is fixed to the lower end of the syringe rod 54, and the commercial empty container W is inserted between the crushing plate 55 and the base 50. Has been put into practical use by crushing the container W to reduce the volume.

However, such a press device requires a space for accommodating an empty container on a large base, and further requires that a hydraulic cylinder having a stroke greater than the height of the empty container be provided upright, and the device is extremely bulky. When the building is low, it is difficult to install, and since it is not a production machine, expensive ones are necessary but difficult to purchase.

Furthermore, in actual factories, the number of empty containers is not so large as to always use the press equipment, but the number generated and accumulated every day is enormous, and it is necessary to install dedicated expensive equipment, which reduces cost. And space.

DISCLOSURE OF THE INVENTION In view of the above problems, the present invention provides a work processing machine capable of easily and inexpensively crushing or reducing an empty container for business use without using a bulky and expensive device. Make it an issue.

The inventor of the present invention has found that a forklift generally installed in a factory or the like can lift a load with a large lift when the fork is lifted, and can increase or decrease the lifting speed and lift by operating an accelerator, and can obtain a large stroke. Attention was paid to the fact that it was not so bulky, and the present invention was completed.

Therefore, the work processing machine using the forklift according to the present invention is fixed to the ground by a riding plate on which the front wheel of the forklift rides (the rear wheel may also ride at the same time) and the upper limit of the fork lifting operation. A fork lift, preferably a fork lift increased by the lift plate and the abutment, which are two load final support points. Is converted into a compressive force, and the compressive force is applied to the work.

The present invention has a great effect if it is used for crushing or reducing the volume of an empty container for business use, but it is used for other work such as packing, demolition, crushing and loosening, draining and squeezing, and cutting using a cutting blade. It can also be applied to applications. Furthermore, it is also possible to convert the compressive force into another force, for example, a pulling force or an extruding force and use the attachment to act on the work, for example, to tear the work.

The forklift may be an engine-type or battery-type forklift, as long as it has front wheels and lifts the load by lifting the fork. The workpiece may be processed upright or may be processed sideways. The processing direction may be a fork rising direction, or a horizontal direction or a fork lowering direction provided with a conversion mechanism. In this case, the structure of the conversion mechanism is not particularly limited. The structure of the receiving plate is not particularly limited as long as the receiving plate is fixed to the ground by a riding plate and regulates the upper limit of the fork lifting operation. For example, the position of the receiver may be fixed, or the position may be adjusted automatically or manually. When the mounting position is adjustable, the empty stroke of the fork can be reduced depending on the size of the work.

More specifically, the present invention more specifically provides a base plate fixed on the ground by a riding plate, a receiving plate supported by the base plate, and for regulating an upper limit of a fork lifting operation, and provided so as to be able to advance and retreat with respect to the receiving plate. And a movable plate that is moved forward and backward by a fork, and the work can be strongly compressed between the movable plate and the receiving plate.

When the work processing direction is the fork lowering direction, the receiving plate is mounted on the base plate, or the base plate has the function of the receiving plate. The connection structure between the riding plate and the base plate is not particularly limited as long as the base plate can be fixed on the ground by riding the forklift. For example, the riding plate may be placed or locked on the front edge of the base plate, may be integrally formed, can be detachably attached to the base plate by a horizontal or vertical connecting pin, and can be raised and tilted by the horizontal connecting pin. May be attached.

When the work processing direction is the fork ascending direction, a support member is erected on the base plate, a receiving plate is fixed to an upper end of the support member, and a movable plate is slidably supported on the support member,
The movable plate is directly or indirectly lifted by a fork, and the work can be strongly compressed between the movable plate and the receiving plate. A support, a plate, or the like can be employed as the support member. In the case of a support, one or more support posts may be provided on the left and right.

The receiving plate is fixed vertically to the fork ascending direction by the support member. However, if a mechanism for converting fork lift into a lateral force is provided, the receiving plate may be fixed in parallel to the fork elevating direction. The supporting member supports the movable plate vertically below the receiving plate so that the work can be strongly compressed between the movable plate and the receiving plate. The movable plate is not always necessary because it can be compressed.

In addition, it is possible to selectively use gentle compression and shock compression by adding an effective device to the work processing. For example, when compressing an empty can from which the lid has been removed, it is preferable to attach a checker plate having a large number of protrusions to the facing surface of the receiving plate and the movable plate so as to easily release the air inside the can.

It is good in terms of space to employ a mechanism for increasing the power by using a pulley as the boosting mechanism. Specifically, a locking plate locked to a fork, a plurality of wheel means supported at mutually symmetrical positions on the left and right sides of the movable plate, one end on the receiving plate, and the other end on the locking plate. It can be constituted by at least a pair of wire means fixed to the wheel means and installed on the wheel means so that the fork lift can be increased in the middle. The wheel means may be a pulley or a sprocket. In the case of a pulley, the wire means can use a wire rope, belt, roller chain or ring chain. In the case of a sprocket, a roller chain is used.

Description of a preferred embodiment [First embodiment] Figs. 1 to 4 show a first embodiment of the present invention. In the drawing, pillars (support members) 11, 11, 11, 11 are erected at four corners of a substantially square base plate 10,
A support plate 12 for restricting the upper limit of the fork lifting operation is fixed to the upper ends of the columns 11, 11, 11, 11. Four pillars 11, 1
A movable plate 14 is slidably supported below the receiving plate 12 at 1, 11, and 11 while maintaining a horizontal state.
The lower position is positioned by lower large diameter portions 13, 13, 13, 13 of 1, 11, 11 and a pair of receiving brackets 17, 17, 17, 17 are provided on the lower surface of the base plate 10 on the right and left sides respectively. It is fixed at a distance and protruding forward.

Outside the right and left receiving brackets 17, 17, two mounting plates 15, 15 are respectively mounted on the outer side of the mounting brackets 19, 19, and are connected by horizontal connecting pins 18, 18 so as to be able to stand up and tilt. As shown in FIG. 2, the work-up processing machine can be stored in a small space by raising the riding plate 15 as shown in FIG.

Also, since the mounting bracket 19 of the riding plate 15 is set to be offset from the width center of the riding plate 15 and is set outside the receiving brackets 17 and 17 on the base plate 10 side, the mounting bracket 19 is provided between the tires 34 and 34 of the forklift 30. Accordingly, the left and right sides of the two riding plates 15, 15 can be interchanged to adjust the distance between the two. Further, from the viewpoint of safety, it is preferable to take measures such as stopping the rising plate 15 around the work processing machine with a chain or the like so that the rising plate 15 in the standing state does not suddenly fall forward.

The riding plate 15 is thick enough to allow the forklift 30 to ride, and is set to withstand the load. The wheel stopper 16 is fixed to the upper surface of the front end, and unevenness for preventing slippage is engraved on the entire upper surface. Has been established.

The work processing machine of this example is used in combination with a forklift, but the forklift 30 basically has the following structure. That is, the fixed mast 32 is supported on the vehicle body side so that the inclination angle (see A in FIG. 4) can be adjusted. A movable mast 33 is slidably supported by the fixed mast 32, and can be driven to rise with a predetermined lift by a hydraulic cylinder or the like. This movable mast
The left and right forks 31 are supported by 33, and the forks 31 can be adjusted to adjust the left and right distance.

Next, the method of use will be described. Ride plate
After 15 is knocked down to the state shown by the solid line in FIG. 2, as shown in FIG.
Then, the front wheel 34 is moved forward until it hits the tire stopper 16 of the riding plate 15 so as to ride on a position forward of half of the riding plate 15, and the fork 31 is inserted into the space below the movable plate 14 between the columns 11. .

When the movable mast 33 is raised by appropriately operating the accelerator of the forklift 30 in such a state, as shown in FIG.
Since the fork 31 lifts the movable plate 14, if the commercial empty container W is put on the movable plate 14, the commercial empty container W
When the fork 31 is sandwiched between the movable platen 12 and the movable platen 14 and further raised by acceleration, the receiving platen 12 is fixed on the ground by the pushing action of the climbing plate 15 on which the forklift 30 has climbed, and is resistant to fork lift. Is the ultimate support point for the fork, so the fork lift
The commercial empty container W is converted into a compressive force by the receiving plate 15 and the receiving plate 12, and is strongly compressed by the receiving plate 12 and the movable plate 14 to be crushed. The compression force at this time is determined by the forklift force of the forklift 30. Further, in order to efficiently transmit the fork lift to the movable platen 14, it is preferable that the movable platen 14 is located at the root side of the fork 31. When taking out the work W after compression, the fork 31 may be lowered and taken out from the work processing machine.

When the forklift 30 has been compressed or returned to the transportation business, move the forklift 30 backward, raise the riding plate 15 and then fork the forklift 30
It is sufficient to insert the 31 below the base plate 10 or below the receiving plate 12, lift it up, transport it to an appropriate place, and store it.

Also, the fork 31 can be inserted above the movable plate 14 to perform strong compression between the fork 31 and the receiving plate 12. In addition,
It can be used in a structure in which the movable platen 14 is removed, a larger space can be formed below the receiving plate 12, and a large work can be compressed.

Second Embodiment FIGS. 5 to 8 show a second embodiment of the present invention. In the figures, the same reference numerals as those in FIGS. 1 to 4 indicate the same or corresponding parts. In the present embodiment, holding plates 20, 20 are erected on both sides of the upper surface of the receiving plate 12 and fixed by welding or the like, and recesses are formed at the upper edges of both holding plates 20, 20 in the vicinity of the riding plate 15 side. A locking plate 21 is mounted on the left and right recesses so as to extend in the width direction of the receiving plate 12, and a reinforcing plate 22 is fixed on the upper surface of the locking plate 21 so as to extend in the width direction.

As shown in FIG. 5, three guide pulleys (wheel means) 24, 25, and 26 are rotatably supported on each of the left and right holding plates 20, 20, one on the riding plate 15 side and two on the opposite side. The two guide sheaves 24 and 25 on the opposite side are arranged at a predetermined distance in an oblique direction.

As shown in FIG. 5 and FIG.
The mounting shafts 280, 280 are attached so as to extend in the width direction at a predetermined interval from each other, and the movable platen 14 is reinforced by the mounting shafts 280, 280. Wheel means) 28, 28 are rotatably mounted.

The mounting plate is fixed to the opposite side of the riding plate 15 by a mounting bracket, and the booster mechanism is configured as described above.

It is to be noted that, instead of using two roller chains 29, 29 on one side, a single roller chain is similarly laid and the middle is fixed to the receiving plate 12 with a mounting bracket, and the same effect is exerted. Also, the riding plate 15 and the base plate 10
Is connected by two horizontal connecting pins 18 to ensure the strength of the connection against a high load, while at the time of standing, one horizontal connecting pin 18 is pulled out to stand.

Next, the method of use will be described. When the drum W is crushed, the front wheel 34 of the forklift 30 is ridden on the riding plate 15 until it hits the tire stopper 16, and the fork 31 is inserted below the locking plate 21 so that the fork lift is transmitted to the locking plate 21 as it is. The locking plate 21 is located on the base side of the fork 31.

When the locking plate 21 is lifted with the fork 31 in such a state,
The two right and left roller chains 29, 29, 29, 29 are each pulled upward, and the two left and right moving pulleys 28, 28, 28, 28 are lifted upward.
Can be compressed between

At that time, the lift of the fork 31 is doubled by the moving pulley 28 and the roller chain 29 turned back there,
Since a compressive force twice the lift of the fork 31 acts on the drum W, the strong drum W can be reliably crushed and reduced in volume without using the large forklift 30.

By the way, two moving pulleys may be lifted by one roller chain on each of the left and right sides.
Since there are only two moving pulleys on the roller chain of the book, the movable platen may be overturned, that is, it may be biased, and the moving pulleys may be connected with a support member or the front and rear moving pulleys may be synchronized. It is necessary to provide a mechanism for moving up and down, for example, a synchronization mechanism using a sprocket and a chain. In this embodiment, two roller chains on the left and right, and thus four roller chains

INDUSTRIAL APPLICABILITY According to the present invention, a front plate of a forklift is caused to ride on a riding plate, and the receiving plate is fixed to the ground by the riding plate. There may be two possible load ultimate support points, i.e., points that ultimately receive a load, whereby the fork lift, preferably the increased fork lift, is converted to a compressive force and applied to the workpiece directly or by another attachment. To work on the workpiece.

As a result, it is possible to construct a work processor useful for a variety of uses, from soft processing to shocking processing for a wide variety of works. In particular, even though a large processing stroke can be obtained, the maximum height of the work processing machine is up to the maximum height of the movable mast of the forklift and does not become bulky, so that it can be easily applied to an ordinary factory building.

Also, when the work needs to be processed, the forklift can be run to the work processing machine to perform the processing using fork power. In addition, expensive mechanical equipment such as hydraulic pumps and valves are not required, and a reliable and highly reliable work processor that can be used for a long time without any failure can be constructed. In addition, when work processing is not required, the forklift can be used for transportation work, while the work processing machine may be installed in an industrial corner or the like, which is advantageous in terms of space, and particularly requires low cost. Ideal for waste disposal. In other words, when a forklift is used as a work processing machine, there is no need to mount components or install equipment, and the work processing machine can be used immediately by lifting a pallet loaded with loads, while the original forklift can be used immediately. Can be returned to use.
