Description

The present invention relates to a dock shelter, which is an airtight device for bringing a building entrance and a transport vehicle into close contact with each other without a gap.

A dock shelter is an airtight device for bringing a building (warehouse, factory, etc.) into close contact with a transport vehicle (truck, container, etc.) without any gaps. Using a dock shelter helps prevent outdoor and indoor air inflows and outflows and keeps the room temperature constant. It is also suitable for places that require a clean environment because it can block the invasion of rain, wind, dust, and pests.

As a conventional dock shelter, there is one disclosed in Japanese Patent Application Laid-Open No. 10-267520 (Patent Document 1). In the dock shelter disclosed in the same document, at least one of the left and right side pads is provided so as to be movable and driveable, and the distance between the side pads is adjusted so as to correspond to each width of the transport vehicle of different sizes. The upper curtain is driven up and down along the front surface of the side pad, and the bottom pad can be adjusted in height so as to correspond to the height of each vehicle floor of transport vehicles of different sizes. The upper curtain and each pad are electrically movable.

The operation procedure of the dock shelter having such a configuration is as follows. First, the truck driver gets out of the driver's seat and opens the rear door of the truck. Then, push the side pad switch to move the side pad to an appropriate position. Then, the truck driver gets on the truck and touches the putt. The driver gets off and presses the switch to lower the upper curtain. The upper curtain stops where it hits the truck roof. After that, luggage is taken in and out between the building and the transport vehicle.

Japanese Unexamined Patent Publication No. 10-267520

In the conventional dock shelter as disclosed in Patent Document 1, there is a convenience that the side pad in the horizontal direction and the upper curtain in the vertical direction can be moved according to the size of the truck. However, it is necessary to operate the side pad and the upper curtain separately twice, and there is a problem that the operability of the operator (truck driver, etc.) is poor.

Therefore, the present invention has been made in view of such a problem, and an object of the present invention is to provide a new and improved dock shelter capable of improving the operability of an operator. ..

(First Embodiment)
The dock shelter according to the first embodiment will be described with reference to FIGS. 1 to 3. The dock shelter 100 is for bringing the carry-in entrance of a building (warehouse or factory) into close contact with a transport vehicle (truck or container) without a gap, and has a floor height of the second floor (for example, a height of 1 m). It is provided on the floor line FL. As shown in FIG. 1, the dock shelter 100 includes a fixed pad 110 that covers one side of the transport vehicle, a movable pad 120 that covers the other side of the transport vehicle, and upper pads 130 and 140 that cover the upper side of the transport vehicle. To be equipped. The fixed pad 110 and the movable pad 120 are also collectively referred to as a side pad.

As shown in FIG. 2, the dock shelter 100 can change the positions of the movable pad 120 and the upper pad 130 according to the size of the transport vehicle. The movable pad 120 and the upper pad 130 are at the positions shown by the broken lines in FIG. 2 in the case of a large transport vehicle (for example, a 10-ton vehicle). That is, the movable pad 120 is located away from the fixed pad 110, and the upper pad 130 is above. Further, in the case of a small transport vehicle (for example, a 2-ton vehicle), the movable pad 120 and the upper pad 130 are moved to the positions shown by the solid lines in FIG. That is, the movable pad 120 is in a position close to the fixed pad 110, and the upper pad 130 is below.

The operation method of the dock shelter 100 configured as described above will be described with reference to FIG. When the transport vehicle arrives, the driver of the transport vehicle operates the dock shelter 100 as follows. First, the driver of the transport vehicle gets out of the driver's seat and opens the rear door of the transport vehicle. Then, as shown in FIG. 3, the operating lever 132 is operated to move the upper pad 130 to an appropriate height, and the movable pad 120 is manually moved to an appropriate position. Then, the driver gets on the transport vehicle and comes into contact with the fixed pad 110 and the movable pad 120. After that, luggage is taken in and out between the building and the transport vehicle.

According to such a dock shelter 100, the size of the opening can be set according to the type of transport vehicle (two types, large and small). However, this dock shelter 100 can only be used in two patterns, maximum and minimum, and when each putt is stopped in the middle, a gap is generated between the transport vehicle and the putt. In addition, it is necessary for the driver to once go up to the floor line FL, which is the floor height of the second floor (for example, 1 m, which is a height close to the height of the loading platform of the transport vehicle), and then move to the transport vehicle. It was. Conventionally, since the position where the operator operates the dock shelter 100 is not the ground line GL (for example, height 0 m) which is the floor height of the first floor, it is difficult to move and there is a problem in safety. As described above, the dock shelter 100 has some problems. Hereinafter, embodiments that can solve such problems will be described.

FIG. 5 is a diagram conceptually showing a configuration in which the movable pad 220 moves. FIG. 6 is a diagram showing an operation method of the dock shelter 200. First, the configuration of the dock shelter 200 will be described with reference to FIG. In the following description, duplicate description may be omitted with respect to the point that the configuration can be the same as that of the first embodiment.

The dock shelter 200 of the present embodiment is for bringing the carry-in entrance of a building (warehouse or factory) into close contact with a transport vehicle (truck or container) without a gap, and as shown in FIG. 4, the transport vehicle It includes a fixed pad 210 that covers one side, a movable pad 220 that covers the other side of the transport vehicle, and a curtain 230 that covers the upper side of the transport vehicle. A pad operation unit 222 for moving the movable pad 220 and a curtain operation unit 232 for winding and unwinding the curtain 230 are provided at close positions. The dock shelter 200 is provided on the floor line FL, which is the floor height of the second floor. Hereinafter, each component will be described in detail.

(Fixed pad 210)
The fixed pad 210 covers one side of the transport vehicle (left side of the paper in FIG. 4). As shown in FIG. 4, the fixed pad 210 has a rectangular parallelepiped shape fixed to the floor line FL. The fixed pad 210 uses a material that softly absorbs the complicated shape of the transport vehicle, and has very high adhesion. The fixed pad 210 can alleviate the impact when the vehicle body of the transport vehicle hits. More specifically, the fixed pad 210 may be configured by using a cushioning material such as urethane inside and covering the outside with a cover made of vinyl chloride resin. Further, the fixed pad 210 may be configured by stacking a plurality of pads in the vertical direction. The fixed pad 210 can be configured in the same manner as the fixed pad 110 of the first embodiment or a general pad (side pad) except for the points not described here.

(Movable pad 220)
The movable pad 220 covers the other side of the transport vehicle (on the right side of the paper in FIG. 4). The movable pad 220 can move in a direction closer to and away from the fixed pad 210 (left-right direction). A wheel is provided below the movable pad 220, and a rail R for guiding the movement of the movable pad 220 is provided below the wheel. The structure of the pad portion of the movable pad 220 itself can be configured in the same manner as the fixed pad 210.

The movable pad 220 can be moved and operated by the pad operation unit 222. As shown in FIG. 4, the pad operation unit 222 is provided on the left side of the dock shelter 200. The pad operation unit 222 is provided at a position (for example, within 1 m) in the vicinity of the curtain operation unit 232 for operating the curtain 230, which will be described later. The curtain operation unit 232 is composed of a loop-shaped chain, and hangs down at a height that can be operated by the operating driver. The operator can operate the curtain operation unit 232 from the ground line GL, which is the floor height of the first floor.

The movable pad 220 is connected to the pad drive unit 224 above the movable pad 220. FIG. 5 is a diagram conceptually showing a configuration in which the movable pad 220 moves. As shown in FIG. 5, the pad drive unit 224 is provided with a rail 224a in the movable range of the movable pad 220. Two runners 224b are arranged on the rail 224a so that they can run. The lower ends of the two runners 224b are connected to both ends of the movable pad 220, respectively.

One end of the pad operating portion 222 is rotated by a turning portion 224c provided at the end of the rail 224a and connected to a runner 224b arranged near the fixed pad 210, and the other end is connected to the runner 224b. Is directly linked to. By pulling one end of the pad operating portion 222, the movable pad 220 moves in a direction away from the fixed pad 210. Further, by pulling the other end of the pad operating portion 222, the movable pad 220 moves in the direction approaching the fixed pad 210. In this way, the driver who is an operator can operate both the curtain 230 and the movable pad 220 at the same position, and the operability is improved.

(Curtain 230)
The curtain 230 is a roll-type curtain that covers the upper part of the transport vehicle. The curtain operating portion 232 for operating the curtain winding shaft 234 is provided at a position near the pad operating portion 222 on the left side of the dock shelter 200. The curtain operation unit 232 is composed of a loop-shaped chain, and hangs down at a height that can be operated by the operating driver. The operator can operate the curtain operation unit 232 from the ground line GL. When the operator rotates the loop-shaped chain in one direction, the curtain winding shaft 234 rotates to raise the curtain 230, and when it is rotated in the other direction, the curtain 230 lowers. Such a mechanism can be configured in the same manner as a general roll curtain or roll screen.

Further, the curtain 230 is provided with one or more cuts 110a in the hanging direction of the curtain 230. It is prevented that the vehicle body of the transport vehicle hits the curtain 230 and is damaged. Further, since the curtain 230 is easily deformed along the shape of the transport vehicle, the airtightness can be improved.

The upper pad 240 is provided above the fixed pad 210 and the movable pad 220. The upper pad 240 has a substantially triangular prism shape in which an inclined surface 240a is provided in the front-rear direction. The curtain winding shaft 234 described above is provided on the upper portion of the inclined surface 240a. In this way, the curtain winding shaft 234 is provided behind the position where the curtain 230 hangs down. It is prevented that the transport vehicle hits the curtain winding shaft 234 and is damaged.

The upper pad 240 of the present embodiment has a different function from the upper pad 130 (or a general upper pad) of the first embodiment. The airtightness of the upper part of the dock shelter 200 can be sufficiently enhanced by the curtain 230. Therefore, the upper pad 240 does not need to be configured in the same form (material or the like) as a general pad.

According to the curtain 230 described above, the heights of various transport vehicles can be adjusted as compared with the upper pads 130 (FIGS. 1 to 3) of the first embodiment. That is, the upper pad 130 shown in FIGS. 1 to 3 could only be used in two patterns, maximum and minimum. If it is stopped in the middle of use, a gap will be generated and the effect of the dock shelter 100 is likely to be lost. The curtain 230 can improve this point.

The configuration of the dock shelter 200 has been described above. Next, the operation (operation method) of the dock shelter 200 will be described with reference to FIG. FIG. 6 is a diagram showing an operation method of the dock shelter 200.

Bring the transport vehicle close to the fixed pad 210. The driver of the transport vehicle gets off. As shown in FIG. 6, the driver unwinds the curtain 230 at the curtain operation unit 232. Unwind until it sticks to the transport vehicle. The movable pad 220 is moved by the pad operation unit 222. Move in the direction close to the fixed pad 210. The order of the operation of the putt operation unit 222 and the operation of the curtain operation unit 232 may be either first. Since the pad operation unit 222 and the curtain operation unit 232 are close to each other, they can be operated at one place, and the operability of the operator is improved.

The driver who has completed the work of transporting the luggage in the warehouse can return the dock shelter 200 to the initial state by the reverse operation of the above. It should be noted that the person who returns the dock shelter 200 to the initial state may not be the driver of the transport vehicle but another person such as a warehouse manager. Also in this case, since the pad operation unit 222 and the curtain operation unit 232 are close to each other, they can be operated at one place, and the operability of the operator can be improved.

(Effect of the second embodiment)
As described above, according to the present embodiment, the pad operation unit 222 for operating the movable pad 220 and the curtain operation unit 232 for operating the curtain 230 are provided at close positions, so that the operator Can be moved to cover both the sides and top of the transport vehicle in one place. In this way, the operability of the operator can be improved.

Further, since the curtain winding shaft 234 is provided behind the position where the curtain 230 hangs down, it is possible to prevent the transport vehicle from colliding with the curtain winding shaft 234, and the curtain winding shaft 234 is damaged. Can be prevented.

Further, since the curtain winding shaft 234 is provided above the inclined surface of the upper pad 240, even when the curtain winding shaft 234 is provided behind the position where the curtain 230 hangs down, the inclined surface of the upper pad 240 causes the curtain winding shaft 234. The curtain 230 can be smoothly wound and unwound.

Further, since the curtain 230 is provided with one or more cuts in the hanging direction of the curtain 230, it is possible to prevent impact and damage when the transport vehicle hits the curtain 230.

Hereinafter, other embodiments to which the first and second embodiments are applied will be described. In the following embodiments, the points different from those of the first and second embodiments will be mainly described, and duplicate explanations may be omitted for the same points as those of the first and second embodiments. ..

(Third Embodiment)
The dock shelter 300 of the present embodiment is the dock shelter 200 of the second embodiment, in which the fixed pad 310 and the movable pad 320 are used instead of the fixed pad 210 and the movable pad 220. Other points are the same as those of the dock shelter 200 of the second embodiment, and thus the duplicate description will be omitted.

The distance between the fixed pad 310 and the movable pad 320 (opening width of the dock shelter 300) is characterized in that, as shown in FIG. 7, the distance between the fixed pad 310 and the movable pad 320 becomes narrower in the direction in which the transport vehicle travels toward the building. That is, the fixed pad 310 is a trapezoidal pillar having a trapezoidal view in a plan view. The movable pad 320 is also a trapezoidal note with a trapezoidal view in plan view. The slopes of the trapezoidal pillar of the fixed pad 310 and the trapezoidal pillar of the movable pad 320 are arranged so as to face each other. In this way, the distance between the fixed pad 310 and the movable pad 320 (opening width of the dock shelter) becomes narrower in the direction in which the transport vehicle advances toward the building, as shown in FIG.

As the movable pad 320, the same one as the fixed pad 310 may be arranged in a different direction. Further, the fixed pad 310 and the movable pad 320 may be triangular prisms instead of trapezoidal columns.

The movable pad 320 is at the position shown by the broken line in FIG. 6 in the case of a large transport vehicle (for example, a 10-ton vehicle having a vehicle width of about 2240 mm). That is, the movable pad 320 is located away from the fixed pad 310. The distance D1 between the fixed pad 310 and the movable pad 320 at this time is about 2.5 m. Further, in the case of a small transport vehicle (for example, a 2-ton vehicle having a vehicle width of about 1740 mm), the movable pad 320 is moved to the position shown by the solid line in FIG. That is, the movable pad 320 is in a position close to the fixed pad 310. At this time, the distance D2 between the fixed pad 310 and the movable pad 320 is about 2 m.

The configuration of the dock shelter 300 has been described above. The operation (operation method) of the dock shelter 300 is the same as the operation of the second embodiment, but the operability is improved as follows for the driver of the transport vehicle. That is, the angle of the door of the transport vehicle in which the door of the loading platform is opened can be matched by the inclination that the opening widens toward the outside. That is, it is easy to absorb the unevenness of the door of the transport vehicle. Normally, in order to obtain such an effect, it is necessary to use a special material or composition for the side pad, but in the present embodiment, it can be realized at low cost.

(Effect of the third embodiment)
As described above, according to the present embodiment, the distance between the fixed pad 310 and the movable pad 320 is configured to be narrower in the direction in which the transport vehicle advances toward the building, so that the transport vehicle stops. Even if the pad is tilted, a gap is unlikely to occur between the fixed pad 310 and the movable pad 320.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the claims, which naturally belong to the technical scope of the present invention. Understood.

For example, in the second embodiment described above, the configuration in which the upper pad 240 is provided has been described, but the present invention is not limited to such a configuration. The upper pad does not have to be provided. Further, an upper pad having a shape different from that of the upper pad 240 may be provided.

The above-described embodiment, application example, and modification can be implemented in any combination.
