Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of a stacking apparatus according to an embodiment of the present disclosure, and fig. 2 to 4 are a front view, a right side view and a top view of the stacking apparatus shown in fig. 1 without a carrying assembly 300.

The stacking apparatus includes a jacking assembly 100, a magazine assembly 200, and a handling assembly 300. The jacking assembly 100 is used for driving the workpiece to ascend or descend. The magazine assembly 200 is adapted to receive and stack work pieces on the jacking assembly 100. The carrier assembly 300 is used to carry workpieces from the magazine assembly 200.

After the conveyor (not shown) conveys the workpiece to a predetermined position, the jacking assembly 100 jacks the workpiece away from the conveyor to drive the workpiece to ascend, and the workpiece is matched with the storage assembly 200 to be transferred to the storage assembly 200. After the jacking assembly 100 sequentially transfers a plurality of workpieces to the magazine assembly 200, the plurality of workpieces are sequentially stacked on the magazine assembly 200. After a predetermined number of workpieces are stacked on the magazine assembly 200, the handling assembly 300 carries the workpieces on the magazine assembly 200 to a packing station for packing. In some embodiments, the handling assembly 300 may not be provided.

The specific structures of the jacking assembly 100, the magazine assembly 200 and the carrier assembly 300 are described in turn below.

Referring to fig. 5 to 7, fig. 5 to 7 are a front view, a right view and a top view of the jacking assembly 100 of the stacking apparatus shown in fig. 1, respectively.

The jacking assembly 100 includes a base 110, a jacking member 130, a first driving member 120, a first limiting member 140, and a second limiting member 150.

The base 110 is fixedly disposed. The base 110 is used to mount the remaining components of the jacking assembly 100. In other embodiments, the base 110 may not be provided.

The lift 130 is capable of moving in the first direction D1 and the direction opposite to the first direction D1 to lift and lower the workpiece. Specifically, the jacking members 130 are slidably engaged with the base 110 along the first direction D1 and can reciprocate along the first direction D1 relative to the base 110. The top of the jack 130 has a bearing surface 131, and the bearing surface 131 is used for bearing a workpiece.

The first driving member 120 is used for driving the jacking piece 130 to move in the first direction D1 or the reverse direction of the first direction D1. Specifically, the first driving member 120 is disposed on the base 110, and a driving end of the first driving member 120 is connected to the jacking member 130. In this embodiment, the first driving member 120 is a cylinder.

The first limiting member 140 and the second limiting member 150 are respectively disposed on the lifting member 130, at least one of which is movably disposed on the lifting member 130, and can relatively approach or depart from the lifting member 130 along the second direction D2, so as to respectively push against the workpiece on the lifting member 130 from two sides during the approaching process, so as to limit the position of the workpiece. In this embodiment, the first limiting member 140 has a first limiting surface 141, and the second limiting member 150 has a second limiting surface 1511. The first and second stopper surfaces 141 and 1511 are spaced apart in the second direction D2. The second direction D2 is parallel to the bearing surface 131. In the approaching process of the first limiting member 140 and the second limiting member 150, the workpiece on the lifting member 130 is pushed from two sides by the first limiting surface 141 and the second limiting surface 1511 respectively. In other embodiments, the second direction D2 may also be inclined with respect to the bearing surface 131.

Before stacking, the workpieces on the jacking member 130 are positioned by the first limiting member 140 and the second limiting member 150, so that the workpieces are in a predetermined position, and the edges of the stacked workpieces are aligned.

In this embodiment, the first limiting member 140 is fixedly disposed on the lifting member 130 and is an integral structure. The first stopper surface 141 forms an L-shape with the bearing surface 131. The second limiting member 150 is slidably engaged with the lifting member 130 along the second direction D2. With the first limiting surface 141 as a reference, the second limiting member 150 pushes against the workpiece, so that the workpiece abuts against the first limiting surface 141. This can improve the positioning accuracy.

The jacking assembly 100 also includes a jacking member 160. The propping member 160 is fixedly disposed on the base 110. The abutting member 160 has a first surface 161. The first surface 161 is obliquely disposed with respect to the first and second directions D1 and D2, respectively. The second limiting member 150 is configured to abut against the first surface 161, so that when the jacking member 130 drives the second limiting member 150 to move along the first direction D1, the first surface 161 can push the second limiting member 150 to move along the second direction D2, and the first limiting member 140 and the second limiting member 150 are relatively close to each other. Through the arrangement of the abutting part 160, the second limiting part 150 can be linked with the jacking part 130, so that the two parts share one first driving part 120, the cost is reduced, and meanwhile, the operation is simple and the control is convenient.

The abutting member 160 further has a second surface 162. The second surface 162 is connected to one end of the first surface 161, parallel to the first direction D1. When the lifting element 130 drives the second limiting element 150 to move along the first direction D1, the second limiting element 150 sequentially abuts against the first surface 161 and the second surface 162. When the lifting member 130 moves along the first direction D1 under the condition that the second limiting member 150 abuts against the first surface 161, the abutting member 160 abuts against the second limiting member 150 to move along the second direction D2. When the lifting member 130 moves along the first direction D1 under the condition that the second limiting member 150 abuts against the second surface 162, the abutting member 160 cannot abut against the second limiting member 150 to move along the second direction D2. By providing the second surface 162, the distance between the first limiting surface 141 and the second limiting surface 1511 can be kept fixed, so that the workpieces on the abutting member 160 can be transferred to the magazine assembly 200.

Jacking assembly 100 also includes rollers 180. The rolling member 180 is rotatably disposed on the second limiting member 150, and the second limiting member 150 abuts against the first surface 161 through the rolling member 180. Since the second surface 162 is further disposed in the embodiment, the second position-limiting member 150 further abuts against the second surface 162 through the rolling member 180. The rolling member 180 may be a roller. By providing the rolling member 180, the resistance to the relative movement of the second limiting member 150 and the abutting member 160 can be reduced.

The jacking assembly 100 further includes a first resilient member 170. The first elastic member 170 is respectively connected to/abutted against the second limiting member 150 and the jacking member 130, and is configured to drive the second limiting member 150 to move in the reverse direction along the second direction D2. Specifically, the second limiting member 150 includes a guide rod 152, a limiting body 151, and a connecting member 153. The second stopper surface 1511 is disposed on the stopper body 151. The guide rod 152 penetrates the lifting member 130 and is in sliding fit with the lifting member 130. The limiting body 151 is fixedly connected to one end of the guide rod 152, and is used for pushing against a workpiece on the jacking member 130. The connecting member 153 is fixedly connected to the other end of the guide rod 152 and is used for abutting against the lifting member 130 to prevent the guide rod 152 from separating from the lifting member 130. The guide rod 152 is sleeved with the first elastic member 170, and two opposite ends of the first elastic member 170 elastically abut against the limiting body 151 and the lifting member 130, respectively. The first elastic member 170 may be a spring.

The jacking piece 130 is in contact with the first surface 161 through the rolling piece 180: during the movement of the lifting element 130 in the first direction D1, the second limiting element 150 overcomes the elastic force of the first elastic element 170 to move in the second direction D2; during the reverse movement of the jacking member 130 along the first direction D1, the elastic force of the first elastic member 170 drives the second limiting member 150 to move along the second direction D2.

During the reverse movement of the lifting member 130 along the first direction D1, the second limit surface 1511 gradually moves away from the first limit surface 141 under the action of the first elastic member 170, so that the first limit surface 141 and the second limit surface 1511 have a sufficient distance to avoid the workpiece before the next workpiece is lifted, and the workpiece can be easily carried on the bearing surface 131 of the lifting member 130.

Referring to fig. 8 to 10 together with fig. 2 to 4, fig. 8 to 10 are a front view, a right side view and a top view of a partial structure of the magazine 200 of the stacking apparatus shown in fig. 1, respectively.

The magazine assembly 200 includes a frame 240, a rack 210, a carrier 220, and a second resilient member (not visible). In this embodiment, the number of the brackets 210, the bearing members 220 and the second elastic members is equal (six), and they correspond to one another.

The frame 240 is fixedly disposed. The frame 240 may be fixedly placed on the ground.

The bracket 210 is fixedly disposed on the frame 240. The bracket 210 includes a connection block 211 and a guide block 212. The connection block 211 is attached to the upper surface of the frame 240. Each connecting block 211 is provided with two guide blocks 212. The two guide blocks 212 are fixedly arranged at intervals on the connecting block 211.

The carrier 220 is rotatably connected to the bracket 210 and can interfere with the bracket 210 to limit the rotation of the carrier 220 in the third direction D3. That is, after the carrier 220 rotates to a predetermined angle relative to the bracket 210 along the third direction D3, the carrier 220 cannot rotate continuously along the third direction D3, but can rotate along the direction opposite to the third direction D3. Specifically, the bearing member 220 is located between the two guide blocks 212 and pivotally connected to the connecting block 211 via a pivot shaft 230. The carrier 220 is substantially triangular.

A second elastic member (not visible) is connected to/abutted against the bracket 210 and the bearing member 220, respectively, for applying an elastic force to the bearing member 220 to drive the bearing member 220 to rotate along the third direction D3. The second elastic member may be a torsion spring. The elastic force of the second elastic member makes the bearing member 220 abut against the bracket 210 without external force.

The bearing component 220 is used for being pushed by the workpiece on the jacking component 130 during the movement of the jacking component 130 along the first direction D1, overcoming the elastic force of the second elastic component, and rotating along the reverse direction of the third direction D3, so as to avoid the workpiece on the jacking component 130, and for blocking the workpiece on the jacking component 130 during the reverse movement of the jacking component 130 along the first direction D1, so as to transfer the workpiece on the jacking component 130 onto the bearing component 220.

The working process is as follows: the lifting member 130 moves along the first direction D1 to lift the workpiece. The workpiece on the lift 130 pushes against the carrier 220, so that the carrier 220 rotates in the third direction D3, and the workpiece moves above the carrier 220. Under the action of the second elastic member, the bearing member 220 is reset (in a state of abutting against the bracket 210). The lifting piece 130 moves along the direction opposite to the first direction D1, and the workpiece is driven to descend. The workpiece is dropped onto the carrier 220.

When the carrier 220 abuts the bracket 210, one side of the carrier 220 is inclined with respect to the first direction D1. The workpiece pushes against the edge to drive the supporting member 220 to rotate in the third direction D3. The bottom ends of the two guide blocks 212 are provided with chamfers for guiding the movement of the workpiece.

In other embodiments, the magazine assembly 200 may not be provided with the second resilient member. During the movement of the lifting member 130 in the first direction D1, the workpiece on the lifting member 130 pushes against the carrier 220 to rotate in the third direction D3. After the workpiece is separated from the carrier 220, the carrier 220 rotates in the third direction D3 under the action of its own gravity until the carrier 220 abuts against the bracket 210.

Referring to fig. 11 to 13, fig. 11 to 13 are a front view, a right side view and a top view of a handling assembly 300 in the stacking apparatus shown in fig. 1, respectively.

The handling assembly 300 comprises a first mount 310, a first jaw 321, a second jaw 322 and a second driver 320.

The first mount 310 is movable.

The first clamping jaw 321 and the second clamping jaw 322 are respectively disposed on the first mounting seat 310, and at least one of the first clamping jaw 321 and the second clamping jaw 322 is movably disposed on the first mounting seat 310, so that the first clamping jaw 321 and the second clamping jaw 322 can approach or depart from each other relatively.

The first mount 310 is moved to the corresponding baling station and the second drive 320 is actuated so that the first jaw 321 and the second jaw 322 are moved relatively away to release the workpiece.

Further, the first mounting seat 310 can rotate around its axis, so that the carrying assembly 300 can drive the workpiece to rotate after grabbing the workpiece. The rotation axis of the first mount 310 is parallel to the fifth direction D5.

Specifically, the carrying assembly 300 further comprises a gear 311, a rack 331 and a third driving member 330.

Because the load on the first mounting seat 310 is large, the first mounting seat 310 is driven to rotate in a gear transmission matching mode, and the operation is more stable.

Furthermore, the first mounting seat 310 can also move in three-dimensional space, so that the handling assembly 300 can move the workpiece after gripping the workpiece.

Specifically, the handling assembly 300 further comprises a mounting frame 340, a second mounting base 350, a fourth driving member 360, a third mounting base 370, a fifth driving member 380 and a sixth driving member 390.

The second mount 350 is slidably coupled to the mount 340 along a fourth direction D4, and can reciprocate along the fourth direction D4 relative to the mount 340. Specifically, the second mounting block 350 may be slidably coupled to the mounting block 340 via a sliding rail slider assembly (not shown). The fourth direction D4 is perpendicular to the fifth direction D5.

The fourth driving member 360 is disposed on the mounting frame 340, and a driving end of the fourth driving member 360 is connected to the second mounting base 350 for driving the second mounting base 350 to reciprocate along the fourth direction D4. The fourth driver 360 may be a cylinder.

Specifically, the third mount 370 may be slidably engaged to the second mount 350 via a guide rod guide sleeve assembly (not identified).

The fifth driving element 380 is disposed on the second mounting seat 350, and a driving end of the fifth driving element 380 is connected to the third mounting seat 370 for driving the third mounting seat 370 to reciprocate along the fifth direction D5. The fifth driver 380 may be a cylinder.

The sixth driving member 390 is disposed on the third mounting seat 370.

The third driving element 330 is disposed at the driving end of the sixth driving element 390. The rack 331 is slidably engaged to the drive end of the sixth drive member 390. The first mounting seat 310 is rotatably disposed at a driving end of a sixth driving member 390, and the sixth driving member 390 is used for driving the first mounting seat 310 to reciprocate along a sixth direction D6. The sixth direction D6 is perpendicular to the fifth direction D5 and the fourth direction D4.

After the workpiece is gripped by the transfer unit 300, the third driving element 330 is operated to drive the workpiece to rotate (the rotation axis is parallel to the fifth direction D5), the fourth driving element 360 is operated to drive the workpiece to reciprocate along the fourth direction D4, the fifth driving element 380 is operated to drive the workpiece to reciprocate along the fifth direction D5, and the sixth driving element 390 is operated to drive the workpiece to reciprocate along the sixth direction D6.

In summary, the stacking device provided by the present application positions the workpiece on the lifting member 130 before stacking, so that the workpiece is at a predetermined position, and further the edges of the stacked workpieces are neat.

Specifically, the above description is only an embodiment of the present application, and not intended to limit the scope of the present application, and all equivalent structures or equivalent processes that are transformed by using the content of the present specification and the attached drawings, or directly or indirectly applied to other related technical fields are also included in the scope of the present application.
