Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting tvC for load-bearing units, such as Ropings Q-Red or similar units, used to support items during transport or storage. The term "load-distribution unit" refers to other types of equipment, even those manufactured by
It also includes units used to support all objects, which, when manufactured, are moved in various assembly, control cabinets or test stations. The term also encompasses other types of load-bearing units designed to facilitate the transfer of the load being supported.

For loading pallets and similar types of load-bearing units, handling operations, such as transporting items from a storage area to another location or transfer vehicle, may be carried out using a Hawklit truck, manually movable fluid-operated lifting device or similar. It is carried out by

Particularly when the transfer distances are short, manually movable devices are used, for example, for transfer operations on lorries or for short-distance transfers in warehouses and the like. As a result, suitable equipment usually has to be carried on the valley transfer vehicle and the corresponding equipment has to be available in the required number in the room where the transfer is to be carried out. For load-bearing units utilized for continuous production, these must be placed on a suitable conveyor, such as a Hubbert conveyor housing, a roller conveyor, or moved between production stations using air impulses. The compressed nitrogen must be supplied to the trough unit and directed by a nozzle towards the floor, thereby directing the air jet from one station to another. The unit has a lifting effect that makes it easier to transport the entire unit.

It is an object of the invention to provide a device which can be used with various types of load-bearing units and which facilitates the transport of the units without the need for any additional transport equipment. The device is particularly suitable for transporting goods over short distances, for example indoors, during loading and unloading of goods on lorries or similar operations. Transfer is accomplished by applying slight manual force. Moreover, although the device according to the invention is based on the use of compressed air, for example on a small container of compressed air provided in a load-bearing unit, the air consumption during the transfer movement is lower than that of known devices of the air-damped type. This means that long-distance transfer can be carried out using a small amount of air, and 11c can be repeatedly transferred over short distances.

The device according to the invention is adapted to be used in conjunction with a load-bearing unit and is characterized by the following features: ing. The device consists of a number of devices mounted on a load support unit, each of which includes a piston member 41 movable in the direction towards the support;
This piston member has a spherical support member II! in the direction toward the support surface! Each device also has an inlet member in communication with a gas outlet under pressure, the inlet member being provided so that the spherical support member is movable in a direction from the four parts.
Facilitating the supply of the gas to a portion adjacent to the end of the piston portion opposite to the C end, and further providing communication between the four portions and an inlet member adjacent to the end on the piston portion side. The spherical support member is provided with a passage 41 to facilitate sliding movement to a position extending outward from the narrowed end on the side of the piston part, thereby being supplied to the side of the input part. The gas moves the piston member and (the housing) the spherical support member back into a position where the spherical support member is in contact with the support surface, at which point the gas flow passes over the spherical support member and the flowing gas is directed against the spherical support member. It is made so that it does not come into contact with the surrounding wall part in the four parts of the enclosure.

Below are the two East m according to this invention? lI't Tri
I will explain this in more detail with reference to the 3J diagram.

The embodiment shown in FIGS. 1 and 2 has a cylindrical enclosing housing l.
In this housing l, a piston fd is arranged so that it can slide over a limited distance. The housing 1 also includes an inlet member 3 which communicates with a source of pressure R1. Four hemispherical portions extend from the end face of the piston member opposite to the inlet member 3, and this recess is provided with a VC so as to completely surround the pan-rule-shaped spherical support portion. The washer-shaped abutment member 6 is attached to this end of the piston member from which the hemispherical recess extends, and the hole provided at the center of the washer-shaped abutment member B is smaller than the diameter of the sol-shaped J*-shaped support hole 5. It has a small diameter and is held in a 6g position completely enclosed by its ball-shaped spherical support member. - On the inlet side, from the end face of the piston member λ facing 10,000, a hole 7 extends in a direction toward the hemispherical Yotsubehiro; The passage 7j widens and transforms into a passageway M at the end 7j, which serves as a valve seat for a longitudinally extending valve member arm extending through the passage r2.

Although the embodiment described above is mounted on a more load-bearing unit as shown for example in Figure 1, Figure 1 shows the loading pallet as a complete unit, designated by the reference IO;
To the unit 10, the floor surface t7t is oriented toward the same surface as the floor surface t7t, and support members 7 are fixed to the unit 10. Each of the supporting members / / , //' has a first,
Referring to Figure 2, a device of the type 7 is arranged, the inlet member 3 of which is attached to a pipe device 7.2 connected to a compressed air container 13, said container 13 having a flow-restricting 5F member/4.
Even if ' is provided, each device is arranged such that the l-shaped spherical support member j is oriented towards the floor casing or similar surface on which the load support unit IO is arranged, and the support member i
i.

//’ is attached.

If the valve member/41F is not shaded, i.e. if compressed air is not supplied to the inlet member 3 and the load support unit IO is in the rest position, each device is operated in the first position shown in FIG. The positioning unit (load support unit) /θ is supported on the supporting floor surface at the r donkey end face of the supports 5lfA' //, 7 //, as usual.

If it is desired to move the load-bearing unit IO, the valve f5 (1, $/) will be affected and the compressed air will flow through the pipe arrangement connected to the inlet port 3 of the kettle arrangement. The compressed air is supplied to each unit from the compressed air container 13 via the I
As a result, the supplied compressed air flows from the hole 7 through the passage t1 into the hemispherical quadrant, thereby causing the pole-shaped spherical member j to move around to the support part of the lower part 1118 of the load-bearing unit IO. When exercise is performed, two selective effects can occur.

If the support part is a completely flat floor surface located just below the end face of the support member / / , / /' surrounding the device,
7. The ball-shaped spherical support shrine j is in contact with its support surface at a position corresponding to the first position shown in FIG. The supplied compressed air then passes through the round spherical support member 6 and flows into a small enclosing air passage formed in conjunction with the washer-shaped member 6 surrounding it. The air pressure acting on the upper surface of the ball-shaped spherical support member j therefore causes a lifting movement of the load-carrying unit lO, whereby said support member j, due to the air flowing around it, There is no mechanical contact with the supporting member! is arranged primarily in a non-frictional manner with respect to the parts surrounding it. Negative for this? The dr support unit can be moved by applying very little manual force.

As already explained, one selective effect is that the valve member/
4' is affected, this effect is obtained during the transport movement when the supporting surface, for example the floor surface, shoulders small irregularities. By the initial sliding movement of the l-shaped spherical support member j relative to the piston member λ, the support member j
If the valve member 3 comes out of contact with the support surface, said sliding movement is carried out until the part of the valve member member adjacent to the inlet member 3 assumes a contact position against the cooperating valve seat within the passage, which Refreshing air is no longer supplied to the hemispherical quadrant, but instead acts on the bore 7 and the end of the piston member λ adjacent to this bore 7. As a result, the piston member moves in the direction towards the support surface until the ball-shaped spherical support member j comes into contact with the support surface. Since the spherical support member j at the time of contact is not affected by any lifting force caused by the compressed air supplied to the recess V surrounding it, the spherical support member j is moved against the valve member by the continuous sliding movement of the piston member λ. The valve member is moved from its sealing contact position with respect to the 9P seat adjacent to the inlet member 3.

For this reason, compressed air is supplied to the hemispherical recess ≠ via the passage rr7. As a result, a lifting position is obtained in which the ball-shaped spherical support member j is mainly in a non-frictional contact state as described above.

During the transport movement, the piston member thus assumes various relative positions to the surrounding housing, depending on the irregularities present on the support surface.

However, there is also another position within t from which the piston member λ facilitates such a transport movement where the spherical support member j is in contact with the support surface.

This condition may occur, for example, when the load support unit IO is moved over a deep hole enclosure or support surface with metal fittings, in which case it is desirable to prevent air from escaping from the device. As shown in FIG. This can be prevented because the cedar spherical support cap comes into contact with the washer-shaped abutment member 6. This ensures that the load support unit IO does not come into contact with the support surface due to the load support, etc.
Air leakage from devices that do not act as support devices can be completely eliminated.

For example, Kutsuzuri M is similar! If passing n/J meeting @-1
When the spherical support member during the transfer movement receives a sudden force, the support part side! is clearly a hemispherical concave V
1) K y can move quickly in the direction toward the bottom of the
Such movement causes the surrounding air passageway to expand for only a short period of time, resulting in excessive air leakage. This leakage, however, is reduced because the valve member is in sealing contact with the valve seat formed by the passageway l and oriented towards the hemispherical four-portion, the supply of this recess into said recessed portion being intermittently. This means that the air consumption is 1! This also results in a decrease in t'x.

In the embodiment described above, a recess V surrounding one spherical support member
is described as hemispherical. However, in view of the fact that such a design is often undesirable from a manufacturing standpoint, a modified IM example is shown in FIG. This embodiment basically overlaps the part provided corresponding to the previous embodiment, but the recess portion is provided as a cylindrical recess, and the washer-shaped abutment member t is formed thicker, The inner edge portion of the hole provided at the center is formed to have a diameter that fits the spherical support member j. According to this embodiment, when compressed air is supplied, four parts ≠
An air passage surrounding the spherical support member J is obtained by the cylindrical wall surface of the housing, and such an air passage is also formed between the spherical support member and the hole provided at the center of the washer-shaped abutment member B. Ru. The operation of this embodiment is as described for the previous embodiment.

During the transfer movement, when the spherical support member j rolls on the support surface, friction occurs between the part of the valve member that is in contact with the spherical support member j and the outer surface of the support member j, causing the valve to A side blade is added to the side.

Such a force occurs when the longitudinal axis of the chip member is located on the centerline of the spherical support member j. However, this problem arises, for example, when the contact surface of the valve member 2 is curved to reduce its size. This problem can be solved in various ways, such as by covering the contact WJ with a suitable friction-reducing material.

A preferred method is to displace the longitudinal axis of the valve member with respect to the center of rotation of the spherical support member, so that the spherical support member! to convert the rotational movement of the valve member into a rotational movement of the valve member, and convert the aforementioned lateral force t into a rotational force acting on the valve member.

One spherical member like the hole already explained! If it does not come into contact with the support part, there is no leakage of air because the Fi valve member 2 is in part, and the spherical support surface j is in contact with the washer-shaped abutment member 6. If the part of the mating member 6 in contact with the spherical support member j is coated with a suitable flexible sealing material such as rubber, synthetic plastic or the like,
Spherical support part l! It should be understood that the 'sealing obtained between the JIAj and the washer-shaped surgical member 6' (r- can be further facilitated).

It should be explained that this twenty-one safety force formula against air leakage is based on the fact that the valve member in the closed button position is no longer in contact with the spherical support member j.

The invention is not limited to the embodiments shown and described, since obviously many modifications can be made within the scope of the inventive concept.

In one embodiment, the piston member λ can be constructed as a unit with two coupling members kN connected at appropriate positions surrounding the spherical support member j. Since the concave portion can be formed in a shape that allows the above-mentioned washer-shaped coupling member B to act, the abutment member 6 can be omitted. Moreover, it has been mentioned that the piston part side parts are arranged in the enclosing groove l so that they can slide a limited distance 'f'.

In the illustrated embodiment described, this means that the piston member 2 is constructed with two different diameters, a first guide-blocking part and a second part with a smaller diameter /6. This is achieved by forming a surface between said diameters and using a joint 177 as a movement limiting member on the cooperating abutment surface of the nozzle l. It is clear that a corresponding movement restriction can be obtained by using other known devices, which makes it possible to form the piston member λ with a constant outer diameter M to reduce manufacturing. In addition, the device is preferably placed on the piston side, 2
It can also be an integrated part with the unit arranged as a cylinder which is allowed to move over a limited distance*t.

For applications where low air consumption is the primary objective, the valve member 2 can also be removed from the arrangement, in which case the closure is placed at the lower edge of the recess 6 surrounding the spherical support member. It can only be obtained for

It should also be mentioned that obviously the compressed air can be supplied in other ways than from the container 13 provided in the load-bearing unit 10.

Compressed air can therefore be supplied to the load-bearing unit 10VC by means of hoses connected to the available compressed air source.

The invention is in no way limited to the embodiments described and shown, since, as mentioned above, many variations are possible;
These examples serve merely as examples within the scope of the inventive concept and the claims.
