Description

Storage space and backflow space shared material turnover frame capable of automatically lifting and lowering and trolley

Technical Field

The utility model relates to a material transport technical field especially relates to a storage space and all revolving racks of material and dolly of can going up and down automatically of backward flow space sharing.

Background

In the prior art, a large amount of materials in a factory area need to be transported to the side of an operation station from a material preparation area by using a transporting device for processing by an operator at the station, and after the processing is finished, the processed materials are transported back to the material preparation area from the side of the operation station or directly sent to the next operation station.

The most common transfer equipment is various customized material transfer racks, or direct outsourcing trolleys and the like. Generally, the chassis of the transfer apparatus is also used as a carrying part, on which a plurality of turnover boxes (such as open plastic boxes of various specifications) can be stacked, and a plurality of materials such as workpieces to be processed are contained in the turnover boxes. The chassis of the prior transfer equipment is designed to be lower (close to the ground), which aims to improve the capacity of a loading area above the chassis as much as possible and simultaneously reduce the gravity center of stacked materials on the chassis as much as possible so as to prevent the materials (and turnover boxes) from dumping.

Meanwhile, in order to facilitate the operator to identify and manage the workpieces at different stages, at least a "storage space (for storing the workpieces to be processed)" and a "reflow space (for storing the workpieces that have been processed and are waiting to be sent out or other objects to be collected)" are generally defined near the work station. An operator generally takes a workpiece from the storage space, conveys the workpiece to be machined to a machining station, and conveys the machined workpiece to the reflow space after machining is completed.

In the prior art, the "storage space" and the "reflow space" are generally arranged in parallel in the spatial layout. Because if the two spaces are stacked one above the other, the workload of the operator is increased. For example, if the "storage space (a plurality of turnover boxes for storage)" is stacked above the "return space (a plurality of turnover boxes for recycling materials)", the operator can directly take the workpiece from the "storage space" each time the operator takes the workpiece to be processed, but the operator needs to move the "storage space (a plurality of turnover boxes for storage)" above each time the operator returns the processed workpiece, so that the opening of the "return space (a plurality of turnover boxes for recycling materials)" can be exposed, and the processed workpiece can be put in the opening; then, the "storage space (containers for storage)" temporarily set aside is reset and superimposed on the "reflow space" (if not returned, the earliest two-space parallel arrangement state is actually returned). This significantly increases the workload on the operator.

In the prior art, the storage space and the reflow space are arranged in the upper and lower positions on the spatial layout (similar to a bookshelf, regardless of who is on the upper side or who is on the lower side) through a customized turnover frame (and the internal grid division thereof). Obviously, such an arrangement of upper and lower positions can save the floor space of the material stack to a considerable extent, but certain technical problems still exist: the grid division inside the turnover frame is fixed, the applicability to materials with different volumes and different quantities is poor, and the dynamic requirements of operators on the space of the material turnover frame in the operation process can not be particularly met. The dynamic requirements here mean: in the beginning stage, the requirement on the storage space is generally the largest, and the requirement on the reflow space is the smallest (even unnecessary); in the process stage, the requirement on the storage space is gradually reduced, and the requirement on the backflow space is gradually increased.

In addition, the material turnover frame divided into the fixed grids cannot control the ground clearance of the turnover boxes at the uppermost layer (directly used by operators) when the turnover boxes with different numbers are placed. When the number of layers is small, the position of the turnover box at the uppermost layer (directly used by an operator) is very low, and the operator needs to bend over to carry the turnover box; when the number of layers is large, the position of the turnover box at the top layer (directly used by an operator) is high, the operator needs to stretch and put the turnover box at hand, the safety is not high, the physical strength is consumed, and the evaluation of a human-computer interface is poor.

Thus a dilemma arises in the prior art: if the storage space and the reflux space are arranged in parallel, the occupied area of the stack is large, and the space utilization rate is too low; if the storage space and the backflow space are superposed up and down, an operator is inconvenient to operate and cannot meet the dynamic requirement on the space; and the human-machine interface evaluation of both arrangements is poor.

The person skilled in the art aims to solve the above technical drawbacks.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Example 1:

as shown in fig. 1, the utility model discloses a storage space and the sharing of backward flow space can automatic rising material turnover frame, include the frame 1 of constituteing by a plurality of horizontal poles 11 and montant 12. The frame 1 is a regular hexahedron as a whole.

In the embodiment shown in fig. 1, a movable storage platform 21 constituting a storage space and a return platform 22 constituting a return space are provided from top to bottom inside the frame 1. In this patent, the space inside the frame 1 between below the movable storage platform 21 and above the reflow platform 22 constitutes the "reflow space" previously described in this patent.

The removable storage platform 21 and the reflow platform 22 may be identical in structure or may be different as needed.

In this patent, liftable storage platform 21 is connected with frame 1 through elastic component 3. Specifically, the fixed end of the elastic member 3 is fixedly connected with the top of the frame 1 without relative displacement therebetween. The flexible end of the elastic element 3 is connected with the liftable storage platform 21 (in a descriptive sense, the liftable storage platform 21 is hoisted in the frame 1). The flexible end of the flexible member 3 can move up and down relative to the fixed end.

When empty (no load), the liftable storage platform 21 is substantially located at a high level within the frame 1, close to the crossbar 11 at the top of the frame 1.

When bearing load, liftable storage platform 21 produces displacement from top to bottom because of material load weight.

The "load" in the above context refers to the total weight of material in the storage space.

When the load is reduced, the liftable storage platform 21 is reset from bottom to top due to the restoring force of the elastic member 3. Particularly, in this state, the space released below the liftable storage platform 21 can compensate the backflow space, so as to meet the dynamic requirements of operators on the two spaces.

The specific method of use of the above example is as follows:

1. in the unloaded state, the liftable storage platform 21 is located at a high position in the frame 1 because the fixed end of the elastic member 3 is connected with the cross bar 11 at the top of the frame 1. The reflow platform 22 is located at the lowest position within the frame 1.

2. After the circulation boxes containing certain materials (such as workpieces) are stacked on the liftable storage platform 21 through the trays by logistics personnel, the liftable storage platform 21 gradually moves downwards under the action of gravity along with the increase of the number of the circulation boxes containing the materials.

Namely (especially critical): in this state, the reflow platform 22 is located at the lowest position in the frame 1 and has no load. Therefore, the liftable storage platform 21 can almost occupy all the space in the frame 1, so that the maximum loading volume is achieved, and the utilization rate of the storage space in the frame 1 is greatly improved.

In addition, since the height of the turnover boxes is increased due to continuous stacking, the turnover box (and the accommodated materials) positioned at the uppermost layer is always kept at a relatively high position in the frame 1. In the carrying process, the bending range of the logistics personnel is greatly reduced, and the working strength of the logistics personnel is greatly reduced.

3. When liftable storage platform 21 is fully loaded with the back, the commodity circulation personnel shift the other assigned position of production station from the material preparation district with the material turnover frame of this patent.

4. When the material turnover frame with the materials is transported to the production station, the station operator generally opens the bag, puts the auxiliary material (such as tray cover, liner, etc.) on the reflow platform 22, and takes out the materials in the highest turnover box on the liftable storage platform 21.

Namely (especially critical): at this stage, the material turnover box (and the accommodated materials) is fully loaded, the volume and the weight are basically the maximum values, and the requirement on the storage space is also the maximum; at the same time, the volume and weight of the material packaging aids (e.g., tray cover, liner, etc.) are much smaller than the material transfer container (and the contained material), so the space requirement of the return space 22 is not great at this stage.

5. Along with the production station on the operator carry away the turnover case on liftable storage platform 21 (in the storage space), or the material in the turnover case is taken away and is processed, the material in the material turnover case on liftable storage platform 21 reduces, weight reduction, liftable storage platform 21 is because the restoring force of elastic component 3 constantly upwards moves for the distance between liftable storage platform 21 bottom surface and the backward flow platform 22 below increases, the backward flow space on the backward flow platform 22 also progressively increases.

Namely (especially critical): in this state, the space released below the liftable storage platform 21 is used to compensate for the aforementioned backflow space. At this stage, the demand of the storage space of the storage platform 21 that is just elevated is decreasing, and the demand of the reflow platform 22 (due to the continuously added box cover or package liner, etc.) is increasing. The utility model discloses a structural design has satisfied the operator ingeniously in the production process to the dynamic demand in two kinds of spaces in the preceding.

At the same time, as the number of turnover boxes (and the materials contained therein) is reduced, the highest turnover box on the liftable storage platform 21 is substantially kept at a relatively high position in the frame 1. In the process of carrying, the range of stooping of the station operator is greatly reduced, and the working strength of the operator is greatly reduced.

6. After the material on the material turnover frame of this patent used up, the commodity circulation personnel can directly transport the material turnover frame that carries the empty case to the recovery area.

Due to the structure and the using method thereof, the material turnover frame can automatically dynamically adjust the sizes of the storage space and the backflow space without external force in the production process, and the dynamic adjustment is completely matched with the requirements of operators on the two spaces. Therefore, the accommodating space in the frame 1 of the material turnover frame is utilized to the maximum, and when material turnover boxes (and accommodated materials) with the same quantity or volume are stacked, the occupied area is obviously reduced compared with the prior art.

In any state, the turnover box (and the contained materials) at the highest layer on the frame 1 can be basically and always positioned at a relatively high position (far away from the bottom surface and close to the height of the upper half of a normal person) of the frame 1, so that the bending range of an operator is greatly reduced, the working strength of the operator is reduced, and the human-computer interface evaluation of the material turnover rack is improved.

In some embodiments, in order to keep the liftable storage platform 21 substantially vertically displaced and overcome the pendulum type motion, the two sides of the liftable storage platform 21 are further provided with the guiding devices 4 respectively.

In this embodiment, the guiding means 4 comprise a vertical rod 41 fixed to the frame 1 (the vertical rod 41 can also be considered as a kind of vertical rod in the frame 1) and a linear guideway 42. After the liftable storage platform 21 is fixed with the linear slide rail 42, the liftable storage platform can only move along the vertical rod 41 in the up-and-down direction, so that the liftable storage platform 21 is prevented from swinging.

In this patent, the elastic member 3 mainly provides a tension force for restoring the displacement of the liftable storage platform 21, and therefore, a tension spring is preferably used.

The specific specification and model of the elastic part 3 can obtain empirical data through limited experiments; and the corresponding configuration can be carried out by combining with the practical application scene and calculating according to the parameters such as the total weight of the materials in the storage space, the weight of the packaging auxiliary materials in the backflow space and the like. The configured calculation formula is as follows:

F＝k(L-L0)

wherein F is a tensile force, and the tensile force is the total weight of the materials in the storage space;

k is the elastic coefficient of the elastic member;

l is the stretched length of the elastic member;

l0 is the original length of the elastic element.

In addition, according to the requirement, a limiting member 13 may be further disposed on the side of the liftable storage platform 21. The limiting member 13 is substantially a stopper or a rib, and functions to prevent the material on the liftable storage platform 21 from horizontally sliding out of the platform.

Further, in order to facilitate the operation, the frame 1 is provided with a workpiece feeding passage 14 at an upper portion of a side where an operator feeds and picks the workpiece. The delivery passage can be realized by arranging one or more transverse rods appropriately.

In some embodiments, in order to increase the working efficiency, the frame 1 is provided with splicing elements 15 in a bottom position (only the position of which is shown in fig. 1, the splicing elements themselves not being illustrated). In different application environments, the splicing part 15 can be selected from commercially available hooks, magnets, clamping grooves and the like, and can also be customized. The splicing element 15 in this patent can be any structure that splices two transfer racks together. Therefore, the plurality of material turnover frames can be connected in parallel or in series for use, and the operation efficiency of material turnover is obviously improved.

In addition, the frame 1 may be provided with a push-pull handle 16 at an appropriate position for the operator's convenience.

In different embodiments, the top of the frame 1 may also be provided with a buffer platform 23 for the placement of some process materials.

In addition, as an extension of the technical concept of the present patent, the technical solution of combining the gravity sensor with the electric linear sliding rail can also be used to achieve the technical effects basically the same as the technical solution of the present patent.

Example 2:

the utility model also provides a but the automatic rising material turnover dolly of storage space and backward flow space sharing, but it is provided with a plurality of gyro wheels 5 (for example 4) in the below of the sharing of above-mentioned arbitrary storage space and backward flow space automatic rising material turnover frame.

In some embodiments, the roller 5 may be provided with a foot brake device (not shown) to facilitate the operator's parking of the trolley and to prevent abnormal movements.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the principles of this invention without the use of inventive faculty. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
