Description

Technical Field

[0001] The invention relates to a vertical warehouse shelf, in particular to a vertical warehouse shelf and an automatic pinning device and method for preventing a vertical warehouse shelf from falling. Background Art

[0002] During the logistics process, after the material pallet is picked up by the stacker or stacker forklift, it is placed in the cargo unit of the vertical warehouse shelf for storage. The outbound process is that the stacker or stacker forklift takes out the material pallet from the cargo unit of the vertical warehouse shelf to complete the outbound. After the material is fixed on the material pallet, the material pallet is generally placed directly on the vertical warehouse shelf beam at the cargo position of the vertical warehouse shelf. It only relies on the material pallet's own gravity to rest on the shelf beam, and the material pallet is not constrained in front, behind, left, right, and above; for fragile, explosive, anti-fall, valuable and other materials, if they are placed on the high floors of the vertical warehouse, once an earthquake or vertical warehouse vibration occurs, the vertical warehouse as a whole will shake, and the material pallet will slide on the cargo beam of the vertical warehouse and fall off the beam to the ground, causing a safety accident.

[0056] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0057] join Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a vertical warehouse shelf structure according to an embodiment of the present invention. Figure 2 The vertical warehouse rack structure schematic diagram of another embodiment of the present invention. The vertical warehouse rack of the present invention includes a column 2, a crossbeam 1 and an anti-falling automatic pin bolt device 4. The crossbeam 1 is connected to the column 2. The anti-falling automatic pin bolt device 4 is installed on the crossbeam 1 to restrain the material tray 3. It is necessary to process the material tray 3 into a through hole through which the pin bolt hook 444 can pass. According to the different structures of the logistics tray, the setting positions of the crossbeam 1 and the anti-falling automatic pin bolt device 4 can be appropriately adjusted. For example, when the material tray 3 is a horizontal through hole 31, the working state of the anti-falling automatic pin bolt device 4 is as follows. Figure 1 As shown; if the material tray 3 is a vertical surface through hole 32, the working state of the anti-fall automatic pin device 4 is as follows Figure 2 As shown. Since the composition, structure, relative position relationship, connection relationship and function of other parts of the vertical warehouse shelf are all relatively mature existing technologies, they will not be repeated here. Only the anti-falling automatic pin device 4 and method of the present invention are described in detail below.

[0058] See also Figure 3 , Figure 3 The figure is a schematic diagram of the installation of an anti-fall automatic pin bolt device 4 according to an embodiment of the present invention. The anti-fall automatic pin bolt device 4 of the present invention is installed on a vertical warehouse shelf, and includes: a support seat 41, which is installed on the beam 1 of the vertical warehouse shelf, and can be preferably two pieces, one end of the support seat 41 is fixed to the side of the shelf beam 1, and the other end of the support seat 41 is connected and fixed to the mounting plate 42, that is, the anti-fall automatic pin bolt device 4 is installed as a whole on the side of the shelf beam 1; a mounting plate 42, which is installed on the support seat 41, and the width of the mounting plate 42 is not greater than the width of the shelf beam 1, so that the mounting plate 42 does not interfere with the material pallet 3 when the material pallet 3 is placed on the upper surface of the shelf beam 1; a driving mechanism 43, which is installed on the mounting plate 42; and a pin bolt mechanism 44, which includes a fixed shaft 441, a connecting rod 442, a rocker rod 443 and a pin bolt hook 444, wherein the fixed shaft 441 is installed on the mounting plate 42, and the pin bolt hook 444 is installed on the fixed shaft 441. On the fixed axis 441; the swing rod 443 is connected to the driving mechanism 43; the two ends of the swing rod 443 are respectively pivoted to one end of the corresponding connecting rod 442, and the swing rod 443 and the connecting rod 442 can be pivoted through a connecting pin 445, and a sliding sleeve or a lubrication structure can be provided on the connecting pin 445 to achieve flexible movement of the connecting rod 442 and the swing rod 443; the other end of the connecting rod 442 is respectively pivoted to the tail of the corresponding pin hook 444, and the connecting rod 442 and the pin hook 444 can be pivoted through a connecting pin 445, and flexible movement between them is ensured; wherein, the driving mechanism 43 drives the connecting rod 442 to move through the swing rod 443, and the connecting rod 442 drives the pin hook 444 to rotate around the axis of the fixed axis 441, and the head of the pin hook 444 switches between a buckled position and an open position.

[0059] See also Figure 4-Figure 6 , Figure 4 This is a schematic diagram of the open position of the anti-falling automatic bolt device 4 according to an embodiment of the present invention. Figure 5 This is a schematic diagram of the closed position of the anti-falling automatic bolt device 4 according to an embodiment of the present invention; Figure 6Schematic diagram of the middle position of the anti-fall automatic bolt device 4 of one embodiment of the present invention. In this embodiment, the connecting rod 442 and the bolt hook 444 are symmetrically arranged on both sides of the swing rod 443. It can also include a limit block 446, which is installed on the crossbeam 1 corresponding to the bolt hook 444. When the bolt hook 444 is in the closed position, the limit block 446 contacts the inner side of the corresponding bolt hook 444. It can also include a swing rod limit block 448, which is installed on the mounting plate 42. When the swing rod 443 swings to a horizontal position, the swing rod limit block 448 contacts and limits the lower surface of the swing rod 443, the driving mechanism 43 stops running and self-locks, and the bolt hook 444 is in the self-locking position. It may also include a pin limit block 447, which is installed on the mounting plate 42 corresponding to the pin hook 444. When the pin hook 444 is located at the maximum open position, the pin limit block 447 contacts and limits the corresponding outer side of the pin hook 444.

[0060] The driving mechanism 43 of this embodiment includes a driving seat 431, a driving component 432 and a coupling 433. The driving seat 431 is mounted on the mounting plate 42. The driving component 432 is mounted on the driving seat 431 and connected to the swing rod 443 through the coupling 433. The driving component 432 can adopt a power system such as a motor, pneumatic, or a steering gear. The rotating shaft in the middle of the swing rod 443 passes through the through hole on the mounting plate 42 and is installed through a bearing (a sliding bearing or a rolling bearing). The middle rotating shaft end of the swing rod 443 is connected to one end of the coupling 433, and the other end of the coupling 433 is connected to the output shaft of the driving component 432. The swing rod 443 can be driven by the rotating shaft to swing back and forth.

[0061] The output shaft of the driving component 432 rotates, driving the coupling 433 to rotate, and then driving the swing rod 443 to swing. When the swing rod 443 swings to a horizontal position, the lower surface of the swing rod 443 contacts and limits the swing rod limit block 448. At this time, the connecting rod 442 and the swing rod 443 are in a nearly straight position, which is the self-locking position of the pin hook 444. That is, if the upper end of the pin hook 444 is subjected to an external force that causes it to open, the force will be transmitted to the lower end of the pin hook 444 and exert force on the connecting rod 442 and the swing rod 443. When thrust is added, the thrust will only be transmitted linearly to the rotating shaft in the middle of the rocker arm 443, and the rigidity of the rotating shaft will withstand the force. The rocker arm 443 will not be affected by the swing force. The driving component 432 stops running and self-locks at this time, so the pin hook 444 is also in the pin self-locking state, and the material tray 3 on the shelf beam 1 is constrained by the pin hook 444; at this time, the rocker arm 443 also enters the limiting groove of the limiting block 446, that is, when the pin hook 444 is subjected to lateral force, it can increase its rigidity.

[0062] When the output shaft of the driving component 432 rotates again, it drives the coupling 433 to rotate, and at the same time drives the swing rod 443 to swing. When the swing rod 443 swings out of the horizontal state, the pin hook 444 will leave the self-locking state and gradually open; as it opens to a certain angle, that is, when the pin hook 444 reaches the contact position of the pin limit block 447, the pin hook 444 is in the maximum open position, which is also the limit position of the swing rod 443 driving the connecting rod 442. This position makes it convenient for the material pallet 3 to be taken out and placed by the vertical warehouse stacker or stacking forklift. The pin hook 444 will not scratch the material pallet 3, making it convenient for the material pallet 3 to enter and exit the warehouse.

[0063] The vertical warehouse rack of the present invention can realize that after the material pallet 3 is placed on the cargo space crossbeam 1, the material pallet 3 anti-falling automatic pin bolt device 4 automatically restrains each material pallet 3, and automatically opens when the material pallet 3 is placed, and automatically closes to restrain the material pallet 3 after the material pallet 3 is placed, preventing the material pallet 3 from sliding due to shaking of the vertical warehouse rack caused by earthquakes and vibrations, thereby improving the safety of the placement of the material pallet 3.

[0064] The anti-falling automatic pinning method of the present invention uses the above-mentioned anti-falling automatic pinning device 4 to prevent the material tray 3 from falling, and includes the following steps:

[0065] Step S100, when storing the material pallet 3, the vertical warehouse stacker or stacking forklift forks the material pallet 3 to the shelf beam 1 position of the vertical warehouse cargo position, and the pin hook 444 of the anti-fall automatic pin device 4 is in an open state;

[0066] Step S200, placing the material tray 3 at a designated position of the shelf beam 1, starting the driving mechanism 43 of the anti-falling automatic bolt device 4, and driving the swing rod 443 to swing along its middle axis through the coupling 433;

[0067] Step S300, the swing rod 443 drives the connecting rods 442 at both sides, and the connecting rods 442 pull the pin hooks 444 at both ends to rotate along the fixed shaft 441, and the pin hooks 444 gradually close;

[0068] Step S400, when the swing rod 443 is in a horizontal position, the pin hook 444 is in a fully closed position and self-locking, and the left and right pin hooks 444 pass through the through holes of the material tray 3 to constrain the material tray 3; and

[0069] Step S500, when taking away the material pallet 3, the above process is performed in reverse to open the pin hook 444 and turn it back to the open position, thereby releasing the constraint on the material pallet 3, and the vertical warehouse stacker or stacking forklift takes away the material pallet 3.

[0070] The automatic pinning device 4 for preventing the material pallet 3 from falling can also be used in conjunction with a vertical warehouse stacker or a stacking forklift, and can realize automatic pinning of the material pallet 3, constrain the material pallet 3, and prevent the material pallet 3 from sliding off the shelf beam 1 due to shelf vibration. When the vertical warehouse stacker or stacking forklift forks the material pallet 3 to reach the shelf beam 1 position of the vertical warehouse cargo position, the pin hook 444 is initially in the open position, and the material pallet 3 is placed in a relatively accurate position on the shelf beam 1 (the accuracy of the material pallet 3 in place is maintained at about ±10㎜); the automatic pinning device 4 for preventing the material pallet 3 from falling is controlled by an automatic control or a manually operated controller, the driving component 432 is started and drives the swing rod 443 to swing along its middle axis through the coupling 433; the swing of the swing rod 443 drives the connecting rods 442 on both sides, and the connecting rods 442 pull The pin hooks 444 at both ends rotate along the fixed axis 441, and the pin hooks 444 gradually close; when the swing arm 443 is in a horizontal position, the pin hooks 444 are in a fully closed position; at this time, the left and right pin hooks 444 have passed through the horizontal through hole 31 or the vertical through hole 32 of the material tray 3 to constrain the material tray 3; when the material tray 3 needs to be removed, the above process can also be performed in reverse, and the two pin hooks 444 are opened and turned back to the open position to release the constraint on the material tray 3, and the vertical warehouse stacker or stacking forklift can take away the material tray 3.

[0071] The present invention realizes that when a stacker or a stacking forklift forks a material pallet 3 and places it on a shelf in a vertical warehouse, the automatic pin bolt device is in an open state. After the material pallet 3 is placed, the pin bolt can be automatically closed to restrain the material pallet 3, and the material pallet 3 will not slide due to shaking of the vertical warehouse caused by earthquakes or vibrations; when the stacker or forklift is ready to fork the material pallet 3 out of the warehouse, the automatic pin bolt can automatically open to facilitate forking out of the warehouse; it can be automatically opened and closed by an automatic control or a manually operated controller; it can realize the automatic pin bolting of the material pallet 3 with a horizontal opening The bolt can also realize the automatic pinning of the vertical opening type material pallet 3. When the material pallet 3 is placed before the shelf beam 1, the pin hook 444 is in the open position; when the material pallet 3 is placed after the shelf beam 1, the pin hook 444 can be automatically in the closed position, which restrains the material pallet 3 and prevents the material pallet 3 from sliding off the shelf beam 1 due to the vibration of the shelf, thereby improving the safety of the storage of the material pallet 3; when the pin hook 444 is automatically opened, the constraint of the material pallet 3 is released, and the material pallet 3 can be taken away from the shelf beam 1.

[0072] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
