Description

The present invention relates to a dock shelter, which is an airtight device for closely contacting a building entrance with a transportation vehicle without a gap.

The dock shelter is an airtight device that allows the entrance of a building (such as a warehouse or factory) and the transport vehicle (such as a truck or container) to be in close contact with each other without any gap. By using a dock shelter, it helps prevent inflow and outflow of outdoor and indoor air, and helps maintain a constant room temperature. In addition, it can block the invasion of rain wind, dust, and harmful insects, so it is suitable for locations that require a clean environment.

As a conventional dock shelter, there is one disclosed in JP-A-10-267520 (Patent Document 1). The dock shelter disclosed in the document is provided with at least one side pad of the left and right side pads so as to be movable, and adjusts the distance between both side pads so as to correspond to each lateral width of transport vehicles of different sizes, The upper curtain is driven up and down along the front surface of the side pad, and the height of the bottom pad can be adjusted so as to correspond to the heights of the floors 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 the proper position. Then, the truck driver gets on the truck and contacts Pat. The driver descends and presses the switch that lowers the upper curtain. The top curtain stops where it hits the truck roof. After that, luggage is taken in and out between the building and the transport vehicle.

JP, 10-267520, A

The conventional dock shelter as disclosed in Patent Document 1 has the convenience that the lateral side pad and the vertical upper curtain can be moved according to the size of the truck. However, the side pad and the upper curtain need to be operated in two separate operations, which poses a problem that the operability of the operator (such as a truck driver) is poor.

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

In order to solve the above problems, according to the present invention, there is provided a dock shelter for closely adhering an entrance of a building to a transportation vehicle without a gap, and a fixed pad covering one side of the transportation vehicle, and the fixed portion. The movable pad that is movable with respect to the pad and covers the other side of the transport vehicle, and the curtain pad provided on the fixed pad and the movable pad can be wound and unwound. A dock shelter, comprising: a curtain that covers the upper side of the vehicle; and a pad operation unit for operating the movable pad and a curtain operation unit for operating the curtain, which are provided in close proximity to each other. Will be provided.

According to such a configuration, since the pad operation unit for operating the movable pad and the curtain operation unit for operating the curtain are provided in the close positions, the operator can place the side of the transport vehicle at one place. It can be moved so that the upper part is covered together. Here, the vicinity position means a state in which an operator can operate in one place without moving, for example, a pad operating part and a curtain operating part are provided within 1 m. In this way, the operability of the operator can be improved.

The present invention can be applied in various ways. The following application examples can be combined as appropriate.
For example, the gap between the fixed pad and the movable pad may be configured to become narrower in the direction in which the transport vehicle advances to the building. As a specific example, the fixed pad and the movable pad may be trapezoidal columns or triangular columns that have the same shape and are symmetrically arranged, and the slopes of the trapezoidal columns or triangular columns may be arranged to face each other. .. Even if the direction in which the transportation vehicle stops is inclined, a gap is unlikely to form between the fixed pad and the movable pad.

The curtain winding shaft may be provided behind the position where the curtain hangs down. It is possible to prevent the transportation vehicle from colliding with the curtain winding shaft and prevent the curtain winding shaft from being damaged.

As an example of a specific configuration in which the curtain winding shaft is provided behind the position where the curtain portion hangs, an upper pad is provided above the fixed pad and the movable pad, and the upper pad is inclined in the front-rear direction. A surface may be provided (for example, a triangular prism or a trapezoidal prism), and the curtain winding shaft may be provided above the inclined surface. Even when the curtain winding shaft is provided behind the position where the curtain hangs down, the inclined surface of the upper pad allows the curtain to be smoothly wound and unwound.

The curtain may be provided with one or two or more cuts in the hanging direction of the curtain. According to this structure, it is possible to prevent impact and damage when the transportation vehicle hits the curtain.

According to the present invention, it is possible to provide a dock shelter capable of improving the operability of a worker. Other effects of the present invention will be described in the modes for carrying out the invention described later.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and the drawings, constituent elements having substantially the same functional configuration are designated by the same reference numerals, and duplicate description will be omitted.

(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 closely contacting the entrance of a building (warehouse or factory) and a transportation 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. Equipped with. The fixed pad 110 and the movable pad 120 are 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 transportation vehicle. The movable pad 120 and the upper pad 130 are located at positions indicated by 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 located 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 line in FIG. That is, the movable pad 120 is located closer to the fixed pad 110, and the upper pad 130 is located below.

An operation method of the dock shelter 100 configured as 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 operation 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 contacts the fixed pad 110 and the movable pad 120. After that, load and unload luggage 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 or small). However, this dock shelter 100 can be used only in two patterns of maximum and minimum, and when each pad is stopped halfway, a gap occurs between the transport vehicle and the pad. It is also 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 close to the height of the bed 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, the height is 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, an embodiment capable of solving such a problem will be described.

(Second embodiment)
A dock shelter 200 according to the second embodiment will be described with reference to FIGS. 4 to 6. FIG. 4 is a diagram showing the configuration of the dock shelter 200. FIG. 5 is a diagram conceptually showing a configuration in which the movable pad 220 moves. FIG. 6 is a diagram showing a method of operating the dock shelter 200. First, the configuration of the dock shelter 200 will be described with reference to FIG. Note that in the following description, repeated description may be omitted for points that can be configured in the same manner as in the first embodiment.

The dock shelter 200 of the present embodiment is for closely contacting the entrance of a building (warehouse or factory) and a transportation vehicle (truck or container) without any gap, and as shown in FIG. 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 are provided. A pad operating section 222 for moving the movable pad 220 and a curtain operating section 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 transportation vehicle (on the left side of the paper surface 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 transportation vehicle, and has a very high adhesion. The fixed pad 210 can reduce the impact when the body of the transport vehicle hits. More specifically, the fixed pad 210 may be configured such that a cushioning material such as urethane is used inside and the outside is covered with a vinyl chloride resin cover. 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 that are not described here.

(Movable pad 220)
The movable pad 220 covers the other side of the transportation vehicle (the right side of the drawing in FIG. 4). The movable pad 220 is movable in a direction toward and away from the fixed pad 210 (a left-right direction). Wheels are provided below the movable pad 220, and rails R that guide the movement of the movable pad 220 are provided below the wheels. The configuration itself of the pad portion of the movable pad 220 can be configured similarly to the fixed pad 210.

The movable pad 220 can be moved and operated by the pad operation unit 222. The pad operation unit 222 is provided on the left side of the dock shelter 200, as shown in FIG. 4. The pad operation unit 222 is provided at a position (for example, within 1 m) near a curtain operation unit 232 for operating the curtain 230 described later. The curtain operating unit 232 is configured by a loop-shaped chain, and hangs down to a height that can be operated by the operating driver. The operator can operate the curtain operating 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 driving unit 224 above it. 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 travel. The lower ends of the two runners 224b are connected to both ends of the movable pad 220, respectively.

The pad operation part 222 has one end turned by a turning part 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 thereof is runner 224b. Are 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 a direction approaching the fixed pad 210. In this way, the driver who is the 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 side of the transportation vehicle. The curtain operating section 232 for operating the curtain winding shaft 234 is provided on the left side of the dock shelter 200 in the vicinity of the pad operating section 222. The curtain operating unit 232 is configured by a loop-shaped chain, and hangs down to a height that can be operated by an operating driver. The operator can operate the curtain operating unit 232 from the ground line GL. When an operator rotates this loop-shaped chain in one direction, the curtain winding shaft 234 rotates and the curtain 230 rises, and when it rotates in the other direction, the curtain 230 descends. Such a mechanism can be configured similarly to a general roll curtain or roll screen.

Further, the curtain 230 is provided with one or two or more cuts 110a in the hanging direction of the curtain 230. The curtain 230 is prevented from hitting and being damaged by the vehicle body of the transport vehicle. Further, since the curtain 230 is easily deformed along the shape of the transportation vehicle, 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 with an inclined surface 240a provided in the front-rear direction. The curtain winding shaft 234 described above is provided above the inclined surface 240a. In this way, the curtain winding shaft 234 is provided behind the position where the curtain 230 hangs. This prevents the transport vehicle from hitting the curtain winding shaft 234 and being 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 portion of the dock shelter 200 can be sufficiently enhanced by the curtain 230. Therefore, the upper pad 240 does not have to be formed in the same form (material etc.) as a general pad.

According to the curtain 230 described above, compared with the upper pad 130 (FIGS. 1 to 3) of the first embodiment, it is possible to match the height of various transportation vehicles. That is, the upper pad 130 shown in FIGS. 1 to 3 could only be used in the two patterns of maximum and minimum. If it is stopped halfway, a gap is 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 (operating method) of the dock shelter 200 will be described with reference to FIG. FIG. 6 is a diagram showing a method of operating the dock shelter 200.

The transport vehicle is brought close to the fixed pad 210. The driver of the transport car gets off. The driver unwinds the curtain 230 with the curtain operating section 232 as shown in FIG. Unwind until it is in close contact with the transport vehicle. The movable pad 220 is moved by the pad operation unit 222. The fixed pad 210 is moved in a direction close to the fixed pad 210. Either the operation of the pad operation unit 222 or the operation of the curtain operation unit 232 may be performed 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 for the operator is improved.

A driver who has completed the work of transporting the luggage in the warehouse can return the dock shelter 200 to the initial state by performing the operation reverse to the above. It should be noted that the dock shelter 200 may be returned to the initial state not by the driver of the transport vehicle but by 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, the operation can be performed at one place, and the operability of the operator can be improved.

(Effects 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 in the proximity position, so that the operator Can be moved in one place to cover both sides and top of the transport vehicle. 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, it is possible to prevent the transportation vehicle from colliding with the curtain winding shaft 234 and prevent the curtain winding shaft 234 from being 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, the inclined surface of the upper pad 240 causes The curtain 230 can be smoothly wound and unwound.

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

Hereinafter, another embodiment to which the first and second embodiments are applied will be described. In the following embodiments, points different from those of the first and second embodiments will be mainly described, and the same points as those of the first and second embodiments may not be repeatedly described. ..

(Third Embodiment)
The dock shelter 300 of the present embodiment is the dock shelter 200 of the second embodiment described above, except that a fixed pad 310 and a movable pad 320 are used instead of the fixed pad 210 and the movable pad 220. The other points are the same as those of the dock shelter 200 of the second embodiment described above, and thus redundant description will be omitted.

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

The movable pad 320 may be the same as the fixed pad 310, but may be arranged with its orientation changed. Further, the fixed pad 310 and the movable pad 320 may be triangular prisms instead of trapezoidal columns.

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

The configuration of the dock shelter 300 has been described above. The operation (operating method) of the dock shelter 300 is the same as the operation of the second embodiment, but the operability is improved for the driver of the transport vehicle as follows. That is, the inclination of the opening that expands outward allows the door of the luggage carrier to match the angle of the door of the opened transportation vehicle. That is, it is easy to absorb the unevenness of the door of the transportation vehicle. Usually, in order to obtain such an effect, it is necessary to use a special material or structure 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 gap between the fixed pad 310 and the movable pad 320 is configured to become narrower in the direction in which the transport vehicle advances toward the building, and thus the direction in which the transport vehicle stops. Even if is tilted, a gap is unlikely to form between the fixed pad 310 and the movable pad 320.

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. It is obvious to those skilled in the art that various changes or modifications can be conceived within the scope described in the claims, and naturally, these also belong to the technical scope of the present invention. Understood.

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

The above-described embodiments, application examples, and modified examples can be implemented in any combination.
