Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a storage device and cold storage. Background Technology

[0002] Refrigeration of fruits and vegetables is a storage method that inhibits the activity of microorganisms and enzymes, thus extending their shelf life. Cold storage technology is the main method of modern low-temperature preservation of fruits and vegetables; refrigerating fruits and vegetables can reduce the incidence of pathogens and the rate of decay, and can also slow down the respiratory and metabolic processes of fruits and vegetables, thereby achieving the goal of preventing spoilage and extending the storage period.

[0003] Mobile fruit and vegetable storage devices, similar to field stations, are frequently used in the preservation of fruits and vegetables. However, the safety of these devices during use is a major concern. When forklifts are used to move these devices, improper stacking of fruits and vegetables by workers can cause the center of gravity of the storage equipment to shift. The fork slots on the traditional cold storage base do not adjust to the forklift fork insertion position as the center of gravity of the cold storage changes. If forklift operations are performed according to the pre-reserved fork slots, the storage unit may tilt and overturn, resulting in unreliable movement of the fruit and vegetable storage equipment. Summary of the Invention

[0004] In order to solve the technical problems of tilting and overturning and unreliable movement of storage devices due to the offset of the center of gravity in the existing technology, a storage device and cold storage is provided that uses a weighing structure to weigh the items inside the shell to obtain the center of gravity of the shell, thereby adjusting the position of the forklift to improve the reliability of movement.

[0005] A storage device, comprising:

[0006] case;

[0007] A weighing structure is disposed on the bottom plate of the shell;

[0008] A base fork plate, wherein the housing is disposed on the base fork plate, and a forklift cooperation structure is provided on the base fork plate;

[0009] The storage device can adjust the forklift cooperation structure based on the detection results of the weighing structure.

[0010] The weighing structure includes a support plate and a position detection mechanism. The support plate is movably disposed within the housing, and the height of the support plate relative to the bottom plate of the housing is adjustable. The position detection mechanism is disposed within the housing and is capable of obtaining the height of the support plate relative to the bottom plate of the housing.

[0011] The position detection mechanism includes at least two detection contacts, all of which are located between the support plate and the bottom plate of the housing, and there is a height difference between two adjacent detection contacts.

[0012] The storage device also includes a display mechanism that is electrically connected to all of the detection contacts.

[0013] The weighing structure also includes a reset mechanism, which is disposed between the support plate and the bottom plate of the housing, and the reset mechanism can drive the support plate to move away from the bottom plate of the housing.

[0014] The number of the support plates is at least two, and all the support plates are evenly distributed on the bottom plate of the shell. The position detection mechanism corresponds to each support plate.

[0015] The forklift assembly includes a fork carriage assembly, which is disposed on the base fork plate and has fork slots for engaging with the fork teeth of the forklift. The position of the fork carriage assembly on the base fork plate is adjustable.

[0016] The forklift assembly includes a drive mechanism, which is mounted on the base fork plate. The fork carriage assembly is connected to the drive mechanism, and the drive mechanism is electrically connected to the weighing structure.

[0017] The forklift engagement structure includes at least two fork carriage assemblies, all of which are arranged side by side on the base fork plate, and each fork carriage assembly is provided with a fork slot for engaging with the fork teeth of the forklift. At most one fork carriage assembly engages with the fork teeth of the forklift at any given time.

[0018] The forklift cooperation structure also includes a blocking mechanism, which corresponds one-to-one with the fork slots and can close the corresponding fork slots. The blocking mechanism is electrically connected to the weighing structure.

[0019] The blocking mechanism includes a baffle and a driving component. The baffle is movably disposed on the corresponding fork slot, the driving component is disposed on the base fork plate, and the baffle is connected to the driving component. The driving component is electrically connected to the weighing structure.

[0020] The base fork plate is provided with at least three forks, and two adjacent forks form a fork assembly.

[0021] A cold storage facility, comprising the aforementioned storage equipment.

[0022] The storage device and cold storage provided by this invention utilize a weighing structure to weigh the items stacked inside the casing, thereby obtaining the center of gravity position of the storage device after the items are stacked. Based on the detection results of the weighing structure, the forklift cooperation structure is adjusted so that when the storage device is moved by a forklift, the items can be picked up at the actual center of gravity of the storage device. This overcomes the problem of the storage device tilting and overturning due to the mismatch between the picking position and the center of gravity in the prior art, ensuring the reliable movement of the storage device.

[0039] Fruit and vegetable mobile equipment is frequently used in the preservation of fruits and vegetables, and its safety during use is a major concern. When transporting fruits and vegetables using forklifts, improper stacking by workers can cause the center of gravity of the equipment to shift after storage. However, the fork slots on the traditional cold storage base do not adjust to the forklift fork insertion position as the center of gravity changes. If forklift operations are performed according to the pre-defined fork slots, the cold storage unit may tip over, resulting in unreliable movement of the fruit and vegetable storage equipment. Therefore, this application provides a method... Figures 1 to 9 The storage device shown includes: a housing 1; a weighing structure disposed on the base plate of the housing 1; and a base fork plate 2, on which the housing 1 is disposed, and a forklift cooperation structure is provided. The storage device can adjust the forklift cooperation structure according to the detection result of the weighing structure. By weighing the items stacked inside the housing 1 using the weighing structure, the center of gravity of the storage device after stacking is obtained. The forklift cooperation structure is adjusted according to the detection result of the weighing structure (i.e., the center of gravity position of the storage device), so that when the storage device is moved using a forklift, the items can be picked up at the actual center of gravity of the storage device. This overcomes the problem of tilting and overturning of the storage device due to the mismatch between the picking position and the center of gravity in the prior art, ensuring reliable movement of the storage device.

[0040] The weighing structure includes a support plate 31 and a position detection mechanism. The support plate 31 is movably disposed within the housing 1, and its height relative to the bottom plate of the housing 1 is adjustable. The position detection mechanism is disposed within the housing 1 and can obtain the height of the support plate 31 relative to the bottom plate of the housing 1. When stacking items, the items can be placed on the support plate 31. At this time, the support plate 31 moves downward under the weight of the items, and its height decreases. The position detection mechanism detects the change in the height of the support plate 31, thereby determining the weight of the items stacked on the support plate 31. Then, according to a preset program, the actual center of gravity of the storage device is obtained. The position of the forklift mechanism can be adjusted according to the actual center of gravity, so that the forklift can pick up items at the position corresponding to the actual center of gravity. This ensures that the actual center of gravity of the storage device is located between the two forks of the forklift, preventing the storage device from tilting and tipping over, and ensuring reliable movement of the storage device. In one implementation, the position detection mechanism includes at least two detection contacts 32. All detection contacts 32 are disposed between the support plate 31 and the bottom plate of the housing 1, and there is a height difference between adjacent detection contacts 32. As the support plate 31 is pressed downwards by the weight of the object, it moves to the position where the detection contacts 32 are located. When the support plate 31 contacts the detection contact 32, the detection contact 32 sends a detection signal to determine that the support plate 31 has descended a set distance. That is, the weight of the object on the support plate 31 has reached the preset weight corresponding to this detection contact 32. At this point, the actual center of gravity of the storage device can be determined according to a preset program. Figure 1As shown in the figure, there are three detection contacts 32. The distances between the three detection contacts 32 and the support plate 31 in its initial position (at which time there are no items stacked on the support plate 31) are L1, L2, and L3, respectively, where L3 > L2 > L1. When items are stacked on the support plate 31, the support plate 31 will move downwards. For example, the relationship between the downward movement distance L of the support plate 31 and L1, L2, L3 is: when L = L1, the support plate 31 moves and touches the detection contact 32 at a distance of L1. At this time, the position detection mechanism can determine that the weight of the items on the support plate 31 at this time is G1, and thus the actual center of gravity of the storage device is determined based on this weight G1; for example, the relationship between the downward movement distance L of the support plate 31 and L1, L2, L3 is: when L = L2... When the support plate 31 moves and touches the detection contact 32 with a distance of L2, the position detection mechanism can determine that the weight of the item on the support plate 31 at this time is G2. Based on this weight G2, the actual center of gravity of the storage device is determined. For example, when the distance L that the support plate 31 moves downward is related to L1, L2, and L3, and L = L3, the support plate 31 moves and touches the detection contact 32 with a distance of L3. At this time, the position detection mechanism can determine that the weight of the item on the support plate 31 at this time is G3. Based on this weight G2, the actual center of gravity of the storage device is determined, thereby adjusting the position of the forklift cooperation structure. The forklift can then reliably move the storage device by cooperating with the forklift cooperation structure, thus avoiding the problem of the storage device tilting and tipping over.

[0041] To facilitate forklift operators in directly confirming the actual center of gravity of the refrigeration equipment, the storage device also includes a display mechanism 33, which is electrically connected to all the detection contacts 32. When the support plate 31 contacts the corresponding detection contact 32, the display mechanism 33 displays the corresponding information. The operator can directly determine the height of the support plate 31 through the display mechanism 33, thereby determining the weight of the items stacked on the support plate 31, and then perform the forklift retrieval according to the corresponding position. Figure 1 As described above, three indicator lights are provided on the housing 1. When the support plate 31 touches the detection contact 32 with a distance of L1, the first indicator light lights up; when the support plate 31 touches the detection contact 32 with a distance of L2, the second indicator light lights up; and when the support plate 31 touches the detection contact 32 with a distance of L3, the third indicator light lights up. The operator can directly determine the forklift position by means of the lights, reducing the difficulty of judging the forklift position when lifting the refrigeration equipment.

[0042] The weighing structure also includes a reset mechanism 34, which is disposed between the support plate 31 and the bottom plate of the housing 1. The reset mechanism 34 can drive the support plate 31 to move away from the bottom plate of the housing 1. By using the reset mechanism 34 to move the support plate 31, the support plate 31 can return to its initial position when the items stacked on it are removed, facilitating preparation for the next weight detection of stacked items. The reset mechanism 34 can be a spring. When the support plate 31 is pressed downward by the stacked items, the spring is compressed and accumulates elastic potential energy. When the stacked items are removed, the spring releases the elastic potential energy, driving the support plate 31 to move upward and eventually return to its initial position.

[0043] The number of the support plates 31 is at least two, and all the support plates 31 are evenly distributed on the bottom plate of the housing 1. The position detection mechanism corresponds one-to-one with the support plate 31. By setting multiple support plates 31, the distribution of the stacked items inside the housing 1 can be accurately detected, improving the accuracy of determining the actual center of gravity of the storage device and further ensuring the reliability of the movement of the storage device.

[0044] by Figure 1 Taking the storage device structure shown as an example, there are two support plates 31 (support plate a and support plate b), and three detection contacts 32. The distances between the support plate 31 and the three detection contacts 32 are L1, L2, and L3, respectively. When an object is placed on the support plate 31, the weight of the support plate 31 when it is pressed down by a distance of L1 is recorded as G1; when it is pressed down by a distance of L2, the weight is recorded as G2; and when it is pressed down by a distance of L3, the weight is recorded as G3. At this time, there are nine possible stacking patterns of items inside the storage device:

[0045] Bearing plate a presses down on L1, bearing plate b presses down on L1 G1+G1 Bearing plate a presses down on L1, and bearing plate b presses down on L2. G1+G2 Bearing plate a presses down L1, and bearing plate b presses down L3. G1+G3 Bearing plate a presses down on L2, and bearing plate b presses down on L1. G2+G1 Bearing plate a presses down on L2, bearing plate b presses down on L2 G2+G2 Bearing plate a presses down on L2, and bearing plate b presses down on L3. G2+G3 Bearing plate a presses down on L3, and bearing plate b presses down on L1. G3+G1 Bearing plate a presses down L3, bearing plate b presses down L2 G3+G2 Bearing plate a presses down L3, bearing plate b presses down L3 G3+G3

[0046] When designing the base fork plate 2 and the forklift cooperation structure, the weight of the stacking mode shown in the table above is applied to the corresponding bearing plate 31. The actual center of gravity of the storage device after stacking items is calculated using this weight, thereby determining the corresponding position of the forklift cooperation structure. This information is preset in the storage device. In actual operation, when items are stacked on the bearing plate 31, the storage device can determine the weight level and stacking condition of the items on the bearing plate 31 based on the downward pressure distance of the bearing plate 31 and the contact point touched. Based on the stacking condition, the storage device can automatically determine the forklift's picking position to ensure reliable movement of the storage device.

[0047] The forklift assembly includes a fork carriage assembly 4, which is mounted on the base fork plate 2. The fork carriage assembly 4 has fork slots 41 for engaging with the fork teeth of the forklift, and its position on the base fork plate 2 is adjustable. When the forklift is used to lift the storage device, the fork teeth of the forklift can extend into the corresponding fork slots 41, which limit the movement of the fork teeth and prevent slippage relative to the storage device, ensuring reliable lifting of the storage device. To adjust the forklift's lifting position, the fork carriage assembly 4 can move on the base fork plate 2, ensuring that the actual center of gravity of the storage device is always above the fork carriage assembly 4. During lifting, the actual center of gravity of the storage device is located between the two fork teeth of the forklift, thus providing reliable support for the storage device and ensuring reliable movement of the storage device. To enable the fork carriage assembly 4 to move relative to the base fork plate 2, the forklift cooperation structure includes a drive mechanism 5, which is mounted on the base fork plate 2. The fork carriage assembly 4 is connected to the drive mechanism 5, and the drive mechanism 5 is electrically connected to the weighing structure. When the weighing structure obtains the weight and distribution of the stacked items on the bearing plate 31, it controls the drive mechanism 5 to operate, thereby moving the fork carriage assembly 4. At this time, the fork slots 41 also move with the movement of the fork carriage assembly 4, and the forklift operator can directly insert the fork tines of the forklift into the corresponding fork slots 41. Figure 5 As shown, the driving mechanism is a cylinder, such as Figure 6 As shown, the drive mechanism is a motor and rack structure. Furthermore, the fork assembly 4 can... Figures 7 to 9 It moves on the base fork plate 2 in a certain way.

[0048] In another embodiment, the forklift engagement structure includes at least two fork carriage assemblies 4, all of which are arranged side-by-side on the base fork plate 2. Each fork carriage assembly 4 is provided with a fork groove 41 for engaging with the fork teeth of the forklift. At most one fork carriage assembly 4 can engage with the fork teeth of the forklift at any given time. In this embodiment, the fork carriage assembly 4 is fixed to the base fork plate 2, and when the storage device needs to be moved, the corresponding fork carriage assembly 4 can be selected according to the actual center of gravity of the storage device.

[0049] To prevent the forklift operator from selecting the wrong fork carriage assembly 4, which could still cause the storage device to tip over during movement, the forklift cooperation structure also includes a blocking mechanism. This blocking mechanism corresponds one-to-one with each fork slot 41 and can close the corresponding fork slot 41. The blocking mechanism is electrically connected to the weighing structure. By blocking unusable fork slots 41, only the slots where the forklift forks insert are open, allowing the operator to directly use the open fork slots 41. The storage device can control the opening of the corresponding blocking mechanism based on the weight of the stacked items obtained from the weighing structure. In one embodiment, the blocking mechanism includes a baffle 43 and a driving member 44. The baffle 43 is movably disposed on the corresponding fork slot 41, and the driving member 44 is disposed on the base fork plate 2. The baffle 43 is connected to the driving member 44, and the driving member 44 is electrically connected to the weighing structure. When it is necessary to block the fork slot 41 without using the fork slot 41, the baffle 43 moves into the fork slot 41 under the drive of the driving member 44, thereby blocking the fork slot 41. When it is necessary to open the fork slot 41, the driving member 44 drives the baffle 43 to move in the opposite direction and move the baffle 43 out of the fork slot 41, thereby opening the fork slot 41. Optionally, the baffle 43 structure at each fork slot 41 can be replaced by an indicator light. Each fork slot 41 has an indicator light, which is intelligently controlled to illuminate according to the stacking mode, indicating that the fork slot 41 is the working position. The operator can then control the forklift's forks to insert into the illuminated fork slot 41 to pick up the goods. The drive component 44 can be a motor.

[0050] To increase the density of the fork assemblies 4 on the base fork plate 2 and improve the reliability of moving the storage device, at least three forks 42 are provided on the base fork plate 2, and two adjacent forks 42 constitute one fork assembly 4. The distance between two adjacent forks 42 is the same as the distance between two fork tines of a forklift. When moving the storage device, selecting the fork 42 adjacent to the left and right of the actual center of gravity of the storage device for lifting ensures reliable movement of the storage device.

[0051] When designing the base fork plate 2 and fork carriage 42, the weight of the stacking conditions shown in the table above is applied to the corresponding support plate 31. The actual center of gravity of the storage device after stacking items is calculated using this weight, thereby determining the actual center of gravity of the storage device after stacking items inside the housing 1. The fork slot 41 numbers and motor numbers on the left and right sides of the actual center of gravity position are recorded. The stacking form corresponds one-to-one with the fork slot 41 opening and the motor, and this correspondence is recorded in the control logic. In actual operation, when a heavy object is placed on the support plate 31, the system determines the level and stacking condition of the heavy object on the support plate 31 based on the downward pressure distance of the support plate 31 and the contact point touched. The system automatically matches the corresponding fork slot 41 opening and motor according to the stacking condition, and controls the motor to work so that the baffle 43 on the corresponding fork slot 41 opening moves up to the corresponding position, ensuring that the forklift fork carriage 42 can be smoothly inserted into the fork slot 41.

[0052] A cold storage facility, comprising the aforementioned storage equipment.

[0053] The cold storage is also equipped with a refrigeration unit, which is located outside the shell and on one side of the base fork plate 2 along its length. The forklift can pick up the storage equipment from the width direction of the base fork plate 2.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
