Description

Technical Field

[0001] The present invention relates to the field of product storage and, more particularly, to a storage device integrated with an automated product storage and retrieval system. Background Art

[0002] Traditionally, storage assemblies consist of several essentially parallelepiped-shaped racks. These racks comprise four vertical columns connected by horizontal cross-members that support the shelves. The shelves define the lower portion of a storage compartment. Typically, the storage compartment is a parallelepiped volume corresponding to a standard pallet. When a product stored therein needs to be removed to prepare an order, a forklift can access the storage compartment via its main face to place the pallet.

[0003] The racks are usually arranged so that the main faces of the storage compartments face each other. The racks arranged in this way define a main circulation span of the forklift, which extends between the two circulation channels that distribute the other spans.

[0004] When it is desired to increase the storage volume for a given floor surface area, increasing the height of the racks to add shelves requires strengthening the fixed connection between the uprights and the cross members in order to withstand the horizontal forces applied to the racks. This usually necessitates a complete modification of the uprights, which, in addition to being costly, requires complete disassembly, reinstallation, and subsequent fixing of the storage components, which means significant operational losses.

[0005] Purpose of the Invention

[0006] It is an object of the present invention to increase the storage and / or packaging capacity of a storage assembly occupying a defined floor surface area. Summary of the Invention

[0007] To this end, a storage assembly is provided, comprising a first substantially parallelepiped storage rack and a second substantially parallelepiped storage rack. The first rack comprises a first lower face that bears on a support surface; a first upper face that is parallel to the first lower face; a first right longitudinal face and a first left longitudinal face that connect the first front transverse face and the first rear transverse face. The first rack defines a plurality of first storage compartments that are stacked along a first stacking direction extending between the first lower face and the first upper face, the plurality of first storage compartments being accessible from the first left longitudinal face and the first right longitudinal face. The first compartments are spaced apart from each other by a first minimum distance along the first stacking direction. The second rack comprises a second lower face that bears on the support surface; a second upper face that is parallel to the second lower face; a second right longitudinal face and a second left longitudinal face that connect the second front transverse face and the second rear transverse face. The second rack defines a plurality of second storage compartments that are stacked along a second stacking direction extending between the second lower face and the second upper face. The second storage compartment is accessible from the second left longitudinal face and the second right longitudinal face. The second compartments are separated from each other by a second minimum distance in the first stacking direction. The first front transverse face and the second rear transverse face are aligned with each other and are separated by a non-zero distance. The first front transverse face and the second rear transverse face are connected to each other by at least one horizontal support structure. The horizontal support structure includes a first support element extending in a first plane, the first plane including the first right longitudinal face or the first left longitudinal face, and / or the second right longitudinal face or the second left longitudinal face. The first support element extends from the first upper face and / or the second upper face to a first predetermined distance from the first lower face and / or the second lower face. The first predetermined distance is 1 to 2 times the first minimum distance or the second minimum distance.

[0008] In this way, a storage assembly is obtained in which the horizontal supports do not need to interfere with the structure of the rack elements, for example by adding reinforcements bonded to opposite vertices of the same storage rack. Then, when it is desired to increase the storage height of the rack element, the previous rack element structure can be maintained and supported from the outside with the help of the support of the invention. By placing the support in a plane including the longitudinal face, the support is particularly easy to put into place. It is possible to produce large supports and / or use lightweight and inexpensive elements since the support extends almost to the entire height of the rack element. Finally, since the predetermined distance is between one and two times the first minimum distance or the second minimum distance, it is possible to develop a support comprising many structural elements without impairing the circulation of the handling machine when carrying parcels from the first compartment or the second compartment.

[0009] The support member of the present invention allows for an economical construction of a rack element, wherein each of the plurality of first storage compartments comprises a first pair of parallel slides extending between a first right longitudinal side and a first left longitudinal side, the first pair of slides being separated by a first minimum distance along a first stacking direction. The economy is particularly significant when each of the plurality of second storage compartments comprises a pair of parallel slides extending between a second right longitudinal side and a second left longitudinal side.

[0010] When the first predetermined distance is significantly greater than the first minimum distance and / or the second minimum distance, the circulation of the carrying carriages carrying the packages may be maintained.

[0011] When the first supporting element comprises a first grid, an efficient support is obtained which is easy to install.

[0012] The efficiency of the support is improved when the horizontal support structure further comprises a second support element extending in a second plane, the second plane comprising the first upper face and / or the second upper face. Advantageously, the second support element comprises a second grid.

[0013] Advantageously, the storage assembly further comprises a third substantially parallelepiped storage rack and a fourth substantially parallelepiped storage rack. The third rack comprises: a third lower face, which bears on the support surface; a third upper face, which is parallel to the third lower face; a third right longitudinal face and a third left longitudinal face, which connect the third front transverse face and the third rear transverse face, one of the third right longitudinal face or the third left longitudinal face facing one of the first right longitudinal face or the first left longitudinal face. The fourth rack comprises: a fourth lower face, which bears on the support surface; a fourth upper face, which is parallel to the fourth lower face; a fourth right longitudinal face and a fourth left longitudinal face, which connect the fourth front transverse face and the fourth rear transverse face, one of the fourth right longitudinal face or the fourth left longitudinal face facing one of the second right longitudinal face or the second left longitudinal face. The horizontal support structure comprises a third support element extending in a third plane, the third plane comprising the first upper face and / or the second upper face and / or the third upper face and / or the fourth upper face. The third supporting element connects the first bracket, the second bracket, the third bracket and the fourth bracket.

[0014] When the third supporting element comprises a third grid, a simple and economical support can be achieved.

[0015] The invention also relates to an order preparation system comprising a storage assembly according to the invention, the order preparation system also comprising automatically guided carriages provided with trays for handling parcels.

[0016] Other characteristics and advantages of the invention will emerge on reading the following description of a non-limiting particular embodiment of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

The second left middle connector 54 is mounted on the second upper end 115.2 of the first left middle column 115, at a second predetermined distance L from the second left middle lower guide 50. 54 Place.

[0081] The first lower end 170.51 of the first left intermediate chain 170.5 is connected to the second lower guide 50, and the first upper end 170.52 of the first left intermediate chain 170.5 is connected to the second left upper middle connector 54. The distance L separating the first lower end 170.51 and the first upper end 170.32 of the first left intermediate chain 170.5 is 170.5 By acting on the second chain tensioner 55 which is identical to the first chain tensioner 46, the distance L is adjusted. 170.5 The first left middle reinforcement net 185 is installed on the first left middle column 115 .

[0082] according to Figure 17 In the tenth step shown, the first left front column 113 and the first left middle column 115 provided with the first left front grid 183 and the first left middle grid 185 respectively are vertically positioned, and the plate 107 is placed on the floor 2.

[0083] According to the final setting step, the positions of the first left front column 113 and the first left middle column 115 are set so that the first lower end 170.31 of the first left front chain 170.3 and the first lower end 170.51 of the first left middle chain 170.5 are located on the horizontal plane P h Once these positions are set, appropriate fixings are made between the plate 107 and the floor 2, if necessary.

[0084] The same installation is performed on the first right rear chain 170, the first left rear chain 170.1, the first right front chain 170.2 and the first right middle chain 170.4 so that the first end of each of these chains is placed in the same horizontal plane P h middle.

[0085] During the first step of the method described above, the attachment of the guide device 20 on the first left front lower portion 113 . 1 of the first left front pillar 113 is done by bolting.

[0086] According to the second step of the method described above, the joining of the first profile 41 to the guide means 20 is advantageously done by bolting the first profile 41 to the lugs 31 of the frame 42 . 1 .

[0087] Finally, as shown in Figure 22, during the sixth step of attaching the first lower end 170.31 of the first left front chain 170.3 to the stopper 21, the first lower end 170.31 is introduced between the pair of lugs 22, and the first pin 44 is introduced through the hole 21 to extend in the hole of the first lower end 170.31.

[0088] The second bracket 200, the third bracket 300 and the fourth bracket 400 are identical here to the first bracket 100. Elements that are identical or similar to those described with reference to the first bracket 100 will have the same reference numerals plus one hundred when they relate to the second bracket 200, plus two hundred when they relate to the third bracket 300, and plus three hundred when they relate to the fourth bracket 400.

[0089] Therefore, if Figure 1As shown, the second rear transverse surface 206 of the second bracket 200 faces the first front transverse surface 105 of the first bracket 100. The third right longitudinal surface 304 of the third bracket 300 faces the first left longitudinal surface 103 of the first bracket 100 and defines a rear center loop span 3. The fourth bracket 400 is positioned such that the fourth rear transverse surface 406 of the fourth bracket 400 faces the third front transverse surface 305 of the third bracket 300. The fourth right longitudinal surface 404 of the fourth bracket 400 faces the second left longitudinal surface 203 of the second bracket 200 and defines a front center loop span 4. The left rear loop span 5 extends along the third left longitudinal surface 303. The left front loop span 6 extends along the fourth left longitudinal surface 403. Similarly, the right rear loop span 7 extends along the first right longitudinal surface 104, and the right front loop span 8 extends along the fourth right longitudinal surface 404.

[0090] like Figure 2 As shown, the rear center span 3, the front center span 4, the left rear span 5, the left front span 6, the right rear span 7, and the right front rear span 8 lead to a center circulation channel 9 bounded by the first front transverse surface 105, the second rear transverse surface 206, the third front transverse surface 305, and the fourth rear transverse surface 406. The rear center span 3, the left rear span 5, and the right rear span 7 lead to a rear circulation channel 10 bounded by the first rear transverse surface 106 and the third rear transverse surface 306. The front center span 4, the left front span 6, and the right front rear span 8 lead to a front circulation channel 11 bounded by the second front transverse surface 205 and the fourth front transverse surface 405.

[0091] The storage assembly 1 is integrated with an order preparation system 90 comprising a first automatically guided carriage 70 and a second automatically guided carriage 80 connected to a control and command unit 91 provided with a wireless communication device 92 with the first carriage 70 and the second carriage 80. The order preparation system 90 also comprises a removal area 93 provided with an unloading ramp 94. Figure 4 The first carriage 70 has a body 71 that is substantially parallelepiped-shaped and includes four motorized drive wheels 72.1 to 72.4, as well as a first gear 73.1, a second gear 73.2, a third gear 73.3, and a fourth gear 73.4. The drive wheels 72.1 to 72.4 allow the first carriage 70 to move back and forth and rotate along a main direction 75 on the floor 2. The gears 73.1 to 73.4 are respectively mounted on the ends of a first retractable arm 74.1, a second retractable arm 74.2, a third retractable arm 74.3, and a fourth retractable arm 74.4. These retractable arms extend from the body 71 parallel to a transverse direction 76 orthogonal to the main direction 75 and substantially parallel to the floor 2. The gears 73.1 to 73.4 are rotatably mounted about an axis substantially parallel to the main direction 75.

[0092] All actuators of the carriage that move the drive wheels 72 . 1 to 72 . 4 , the gears 73 . 1 to 73 . 4 , and the actuators for retracting the retractable arms 74 . 1 to 74 . 4 are connected to a drive unit 77 , which is provided with means for wireless communication with the control and command unit 91 .

[0093] A first camera 78.10 is attached to the first arm 74.1 to capture images of the first gear 73.1 and its surroundings. Similarly, a second camera 78.20, a third camera 78.30, and a fourth camera 78.40 are attached to the second arm 74.22, the third arm 74.3, and the fourth arm 74.4, respectively, to capture images of the second gear 73.2 and its surroundings, the third gear 73.3 and its surroundings, and the fourth gear 73.4 and its surroundings. Cameras 78.10 to 78.40 are connected to the drive unit 77.

[0094] The first bracket 70 receives an upper plate 78 mounted to a slide projecting from the body 71 in the transverse direction 76. The plate 78 comprises lugs 79 extending the projection in a plane orthogonal to the plane of the plate 78. When the wheels 72.1 to 72.4 of the first bracket 70 rest on the floor 2, the upper surface of the plate 78 extends from the floor 2 by a distance h, which is here equal to 260 mm. 78 .

[0095] The structure of the second bracket 80 is the same as that of the first bracket 70 .

[0096] As in Figure 1 and Figure 5 As can be seen more specifically in FIG, the first grid 501 extends in a first vertical plane 502. The first right longitudinal face 104 and the second right longitudinal face 204 also lie in the first plane 502. The first grid 501 is composed of steel angles 503, bolted together to form a triangular system 504 that connects the first right front column 112 and the second right rear column 210. The first grid 501 extends from the first upper face 102 and has a passage height H equal to 485 mm extending from the floor 2. pas first lower end 501.1.

[0097] Therefore, the first grid 501 ensures that horizontal forces of the first bracket 100 are transmitted through the second bracket 200 and vice versa, thereby increasing the resistance of the first bracket 100 to horizontal forces.

[0098] like Figure 6As shown, the second grid 511 extends in a second horizontal plane 512. The first upper face 102 and the second upper face 202 also lie in the second plane 512. The second grid 511 is composed of steel angles 513 that are bolted together to form a triangular system 514 that connects the upper edges of the first bracket 100 and the second bracket 200.

[0099] The third grid 521 extends in the second horizontal plane 512, which also includes the third upper face 302 and the fourth upper face 402. The third grid 521 is composed of steel angles 523, which are bolted together to form a triangular system 524, which connects the first left front column 113, the second left rear column 211, the third right front column 312, and the fourth right rear column 410.

[0100] The first grid 501 , the second grid 511 and the third grid 521 belong to the horizontal support structure 500 .

[0101] The horizontal support structure 500 may further comprise a fourth grid 531 extending in a fourth vertical plane 532, which here also comprises the first left longitudinal face 103 and the second left longitudinal face 203. The fourth grid 531 may be identical to the first grid 501.

[0102] The horizontal support structure 500 may further comprise a fifth grid 541 extending in a fifth vertical plane 542, which here also comprises the third right longitudinal face 304 and the fourth right longitudinal face 404. The fourth grid 531 may be identical to the first grid 501.

[0103] The horizontal support structure 500 may further comprise a sixth grid 551 extending in a sixth vertical plane 552, which here also comprises the third left longitudinal face 303 and the fourth left longitudinal face 403. The sixth grid 551 may be identical to the first grid 501.

[0104] Horizontal support structure 500 may further include a seventh grid 561 extending in sixth horizontal plane 552, which also includes third upper surface 302 and fourth upper surface 402. Seventh grid 561 connects the upper edges of third bracket 300 and fourth bracket 400. Similarly, other horizontal grids similar to second grid 511, third grid 521, or fourth grid 531 may extend between two or more of first bracket 100, second bracket 200, third bracket 300, and / or fourth bracket 400.

[0105] The horizontal support structure 500 is provided at a distance H from the floor 2. pasThe first and second carriages 70 and 80 are stopped so that when they do not support a container, or do not support one of the lower or upper containers, they can circulate in the central channel 9. When the first and / or second carriages support an intermediate container, the unit 91 drives them so that they do not circulate in the central channel 9.

[0106] In operation, when an item stored in one of the storage compartments of the order preparation system 90, for example, an item stored in the first left front lower container 151, is sought to be removed, the removal request is processed by the unit 91. The unit 91 drives the first carriage 70 to bring it into the rear center circulation span 3 so that the first gear 73.1, the second gear 73.2, the third gear 73.3, and the fourth gear 73.4 face the first left front upright 113, the first left middle upright 115, the third right front upright 312, and the third right middle upright 314, respectively.

[0107] Therefore, the drive unit 77 drives the deployment of the first arm 74.1. As shown in Figure 24, the first gear 73.1 is substantially facing the first front chain 170.3. During the deployment of the first arm 74.1, the first camera 78.10 transmits a first image of the relative position of the first gear 73.1 and the first chain 170.3 to the drive unit 77. Based on analysis of this image, the drive unit 77 can adjust the relative positioning of the robot 70 and the first left front column 113 by controlling the wheels 72.1 to 72.4. Once the relative positioning of the first chain 170.3 and the first gear 73.1 is completed, the drive unit 77 controls the deployment of the first arm 74.1 until the first gear 73.1 engages with the first chain 170.3. Similarly, the drive unit 77 deploys the second arm 74.2, then the third arm 74.3 and the fourth arm 74.4, while adjusting the position of the first bracket 70 so that the second gear 73.2, the third gear 73.3 and the fourth gear 73.4 are engaged with the first left intermediate chain 170.5, the third right intermediate chain 370.4 and the third right front chain 370.2, respectively. The movement of the first bracket 70 for adjusting the relative positions of the gears 73.1 to 73.4 and the chains 170.3, 170.5, 370.2 and 370.4 is facilitated in particular by the flexibility of the arms 74.1 to 74.4 in the main direction 75 and the simultaneous or sequential deployment of the arms.

[0108] Rotation of the gears 73.1 to 73.4 in a first rotational direction allows the first bracket 70 to climb vertically relative to the first and third brackets 100 and 300 until it is positioned substantially below the level of the first pair of front lower slides 121. The plate 78 then deploys to extend beneath the bottom of the first left front container 151. Further rotation of the gears 73.1 to 73.4 allows the lug 78 to engage with the corresponding aperture 151.1 in the bottom of the container 151. The unit 91 then controls the retraction of the plate 78 and the rotation of the gears 73.1 to 73.4 in a second rotational direction opposite the first rotational direction to bring the first bracket 70 into contact with the floor 2.

[0109] Once the wheels 72.1 to 72.4 of the first carriage 70 come into contact with the floor 2, the drive unit 77 controls the retraction of the retraction arms 74.1 to 74.4 and drives the first carriage 70 up to the removal area 93 and the ramp 94. After the operator removes the items in the first left front container 151 and confirms the removal, the unit 91 controls the first carriage 70 so that it replaces the first left front container 151 in the first front lower storage compartment 140.

[0110] When first and second carriages 70, 80 are used simultaneously, situations may arise where first and second carriages 70, 80 must cycle within the same span, such as rear center span 3, to access a container or engage removable area 93. The alignment of first front free passage volume 190 and first rear free passage volume 191 allows for the creation of a first additional rear center circulation span 3', which thus extends beneath first front lower compartment 140 and first rear lower compartment 144. First additional rear center span 3' enables the first and / or second carriages 70, 80 to cycle from first front transverse face 105 of first rack 100 to first rear transverse face 106 of first rack 100. Cycling of first and / or second carriages 70, 80 is possible, including when transporting containers such as first right lower front container 150 or first right front upper container 154. During transport of a container similar to the first right front intermediate container 152 of a higher height, the unit 91 controls the first bracket 70 or the second bracket 80 loaded thereby so that it does not use the first additional rear span 3' ( Figure 18 ).

[0111] Of course, the second bracket 200 , the third bracket 300 and the fourth bracket 400 themselves also include front and rear free passage volumes to generate other additional circulation spans.
