Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a picking lift carriage used for taking out and transporting necessary articles from a rack of a warehouse in which various articles are three-dimensionally stored.
[0002]
[Prior art]
Conventionally, when a necessary article is taken out from a rack storing articles (goods) mainly in a distribution center or the like, the pallet is supported by a fork of a forklift, and the article is loaded on the pallet and is lowered to a predetermined place. The vehicle is transported and loaded on a truck or the like, or it is carried on a transport vehicle called a cart with a fence standing and fixed on three sides of the carriage to a predetermined place.
[0003]
[Problems to be solved by the invention]
Therefore, when loading and unloading articles using the pallet, the passage width between the racks of the warehouse is very narrow, so it is not only easy to load articles but also because of the problem of collapse of the loaded articles. Therefore, there is a problem that the work efficiency is low due to the lack of properties and, therefore, the amount of articles to be loaded is limited.
[0004]
Moreover, even if it is going to use the conventional cart, since three sides are surrounded by the fence, it is difficult to load an article when loading it from the rack, and therefore unloading using the cart is not practical. In other words, picking forks that are widely used at present are placed on a work platform connected to a fork that supports the pallet, on the ground or in the air (the first level of the rack is the ground level, the second and higher levels are in the air). Used for removing or storing items from the rack, but the scope of work is limited due to safety standards, so even if a picking wheel is used, work is performed with the wheel close to the safety fence on the picking fork side. As a result, it has been extremely difficult to ensure the cargo handling work and the safety of the work in the conventional cart.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a movable carriage, a rear fence standing on the back of the carriage, and a range extending from the left and right sides of the rear fence to the middle positions on both sides of the carriage. In a picking lift vehicle composed of a side fixed fence standing on the side and a side movable fence that is connected to the side fixed fence so as to be folded back outward and closes or opens the first half of both sides of the carriage. In the lower part of the side movable fence, a fixed wall having a low height and fixed to the carriage is provided.
[0006]
By providing a fixing means for fixing the movement of the side movable fence at the open / closed position, the side movable fence can be operated in a stable state.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to embodiments shown in the drawings.
[0008]
A picking lift carriage 1 according to the present invention has wheels 2 and 2 (one of the front and rear casters) and a rear fence 4 that covers the entire width of the carriage 3 at the rear of the carriage 3 that can be supported by a fork of a forklift. Are fixedly erected, and side fixing fences 5 and 5 which are fixedly erected in a range up to an intermediate position in the longitudinal direction of both sides of the carriage 3 are integrally formed on both sides of the rear fence 4 by connecting members 6, 6. It has a structure having a shallow U-shaped fence in plan view.
[0009]
Side movable fences 7 and 7 that open or close the first half of both sides of the carriage 3 are folded back to the outside of the side fixed fences 5 and 5 by hinges 8 and 8 at the front portions of the side fixed fences 5 and 5. It is pivoted so that it can.
[0010]
On both sides of the carriage 3 in a range where the side movable fences 7 and 7 are provided, fixed walls 9 and 9 made of a plate material or a frame material having a height of about 100 to 200 mm are erected. When the article is loaded on the carriage 3, it does not fall off to the side.
[0011]
The rear fence 4, the side fixed fences 5, 5 and the side movable fences 7, 7 are all gate-shaped frames 4 a, 5 a, 7 a and a plurality of vertical fences 4 b, 5 b arranged in parallel in the vertical direction. , 7b and a plurality of reeds 4c, 5c, 7c. However, this configuration may be an appropriate structure.
[0012]
The side movable fences 7, 7 are provided with a fixing means for making a fixed state at the open / close position. For example, the fixing means is configured such that one of the vertical rods 7b of the side movable fence 7 can be moved up and down, and its lower end is dropped into the fixing hole 10 on the cart 3 side so as to be fixed so that it cannot be opened and closed. . In addition, when folded back, the side fixing fence 5 may be fixed using a clamp-shaped fixing tool.
[0013]
Therefore, in order to take out an article from the rack using the above-described carriage 1, first, the side movable fences 7, 7 are overlapped on the outer side surfaces of the side fixed fences 5, 5, as shown in FIG. Then, the carriage 3 is supported by the fork of the forklift and lifted to the height of the rack, and the article is transferred from the rack onto the carriage 3. At this time, since the front half of the carriage 3 is opened from the front side as well as the left and right sides, even a large article can be easily transferred, and the second half area of the side part is secured by the side fixing fences 5 and 5. Since it is enclosed, it can be combined with the rear fence 4 to prevent the articles from collapsing and can be safely loaded, and since there are fixed walls 9, 9 on both sides of the front half of the carriage 3, The operator is prevented from sliding down.
[0014]
After lowering to the ground with a forklift, the side movable fences 7 and 7 are closed and fixed, so that the three sides are surrounded by the fences 4, 5, and 7 and transported without collapsing the cargo directly to the truck etc. Can be loaded.
[0015]
The connecting tool 6 is a pivoting hinge so that one of the side fixing fences 5 and 5 can be folded inward, and wheels 2, 2... Are provided at the lower ends of the fences so that the base plate 3a can be removed. In this case, the storage space may be reduced by using an L shape in plan view when stored.
[0016]
【The invention's effect】
As described above, according to the present invention, since both sides of the front half of the carriage can be opened at any time, it is easy to lift the cart directly with a forklift and load articles from the rack onto the cart. By lowering the side movable fence and closing the side movable fence, the three sides are surrounded by the fence and can be transported to a predetermined place without collapsing.
[0017]
Especially when loading goods, both sides of the front half of the carriage can be opened to load goods, so even large articles can be easily loaded in a narrow passage. At the time of loading, the rear fence and side fixed fence can be used. It is safe because the articles are prevented from collapsing, and a large amount of articles can be loaded, so that the work efficiency can be improved.
[0018]
If a fixed wall having a low height is provided on the lower carriage of the side movable fence, the article and the operator are not dropped when the article is loaded, and the safety can be further improved.
