TECHNICAL FIELD

[0001] The present application relates to the technical field of front-end loading devices, in particular to a front-end loading device of an in-box stacking equipment. BACKGROUND

[0002] The front-end loading device can refer to the patent with the application number CN201510861386.X. The existing front-end loading device includes a plurality of rotating rollers and a driving mechanism. When the goods are moved to the rotating rollers under the action of the conveying mechanism, the driving mechanism drives the rotating rollers to rotate, and the rotating rollers move the goods transversely until the goods are evenly distributed on the upper side of the front-end loading device. At this time, the goods are closely arranged in a row along the width direction of the front-end loading device, and then the pushing mechanism pushes the whole row of goods out of the front-end loading device.

[0003] The existing front-end loading device for the in-box stacking equipment cannot adjust the width, and the internal width of the container is different for different models, which causes the existing front-end loading device to be applicable only to the stacking operation of a plurality of models of containers. SUMMARY

[0004] The present application proposes a front-end loading device of an in-box stacking equipment to solve the problem that the existing front-end loading device cannot adjust the width.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A front-end loading device of an in-box stacking equipment includes a support, a plurality of rotating rollers rotatably connected to the support, and a first driving mechanism for driving the rotating rollers. The first driving mechanism is arranged in the rotating rollers or on the support. The support includes a support body and a transversely expanding component for supporting the goods and capable of being extended or rotated relative to the support body. The rotating rollers are rotatably connected to the support body. At least one end of the support body is provided with the transversely expanding component. The transversely expanding component is rotated or extended to adjust the width of the front-end loading device of the in-box stacking equipment.

[0007] Through the above-mentioned arrangement, the width of the front-end loading device of the in-box stacking equipment can be increased when the transversely expanding component is rotated to extend horizontally at the end of the support. Alternatively, the length of the transversely expanding component can be adjusted in an extendable manner to adjust the width of the front-end loading device of the in-box stacking equipment.

[0008] Further, both ends of the support body are provided with the transversely expanding component, and the rotating rollers are arranged between the transversely expanding components. The rotating rollers are divided into a plurality of roller groups, each of which is composed of two or more rotating rollers. Each roller group is provided with an independent first driving mechanism to drive the corresponding rotating rollers to rotate.

[0009] Through the above arrangement, when the front end loading device of the in-box stacking equipment is widened by the two lateral expansion assemblies, the length of each lateral expansion assembly can be reduced, thereby reducing the stress of the lateral expansion assembly, and further increasing the stability of the lateral expansion assembly.

[0010] Further, one side of the support body is provided with a push plate and a pushing mechanism for driving the push plate to push the articles on the rotating roller and the lateral expansion assembly.

The support body is provided with a second driving mechanism for driving the connecting seat to move axially along the first supporting rods.

[0014] Through the above arrangement, the stability of article stacking can be increased.

[0015] Further, the lateral expansion assembly comprises a first rotating shaft which is vertically through the connecting beams and rotatably connected with the connecting beams, and a supporting assembly which is fixedly connected with the first rotating shaft and used for supporting the articles. The support body is provided with a first adjusting mechanism for driving the first rotating shaft to rotate.

[0016] Further, one end of the first rotating shaft is fixedly connected with a first pushing rod. The first adjusting mechanism comprises a first electric cylinder. One end of the first electric cylinder is rotatably connected with the connecting beams. The other end of the first electric cylinder is rotatably connected with the first pushing rod.

[0024] Through the above arrangement, the rotation of the second rotating shaft can be realized by the extension and retraction of the second electric cylinder, so that the support plate and the scissor structure rotate around the axis of the second rotating shaft, and when the scissor structure rotates downward by ninety degrees, the width of the present application is small, facilitating the use of the container with small width.

[0025] Further, the second adjusting mechanism comprises a motor fixedly connected with the support plate, a third shifting rod connected with the motor, and a second transmission rod rotationally connected with the third shifting rod, and one end of the second transmission rod away from the third shifting rod is rotationally connected with the lower connecting key.

[0026] Through the above arrangement, the motor can drive the lower connecting key to move through the third shifting rod and the second transmission rod, so as to realize the expansion and contraction of the scissor structure, and further realize the adjustment of the width of the application.

[0042] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0043] Example 1:

[0044] See also Figures 1 to 5 A front-end loading device of an in-box palletizing device includes a bracket, a plurality of rotating rollers 12 rotatably connected to the bracket, and a first driving mechanism for driving the rotating rollers 12. The first driving mechanism is arranged in the rotating rollers or on the bracket. The bracket includes a bracket body 11 and a transverse expansion component 13 for supporting articles and capable of retracting or rotating relative to the bracket body 11. The rotating rollers 12 are rotatably connected to the bracket body 11. The transverse expansion component 13 is provided at at least one end of the bracket body 11. The transverse expansion component 13 is rotated or retracted to adjust the width of the front-end loading device of the in-box palletizing device.

[0045] Through the above-mentioned arrangement, when the lateral expansion component 13 is rotated so that the lateral expansion rod 1153 extends horizontally at the end of the bracket, the width of the front-end loading device of the in-box palletizing equipment can be increased; or, the length of the lateral expansion component 13 can be adjusted by telescopic means, thereby realizing the adjustment of the width of the front-end loading device of the in-box palletizing equipment.

[0046] Specifically, when the width of the front end of the in-box stacking equipment is increased, the conveying mechanism 21 conveys the articles to the rotating rollers 12, and then the first driving mechanism drives the rotating rollers 12 to rotate, so that the articles move laterally to the lateral expansion assembly 13 by a distance, thereby providing space for the articles output by the subsequent conveying mechanism 21, and then the conveying mechanism 21 continues to output the articles to the rotating rollers 12, and so on. When the articles move to one end of the support body 11, the first driving mechanism drives the rotating rollers 12 to rotate, and the articles close to the lateral expansion assembly 13 are pushed to the lateral expansion assembly 13 by the articles behind, thereby realizing the support function of the lateral expansion assembly 13 to the articles.

[0047] As an implementation manner, the support body 11 is provided with the lateral expansion assemblies 13 at both ends, and the rotating rollers 12 are arranged between the lateral expansion assemblies 13. The rotating rollers 12 are divided into a plurality of roller groups, each roller group is composed of two or more rotating rollers 12, and each roller group is provided with an independent first driving mechanism to drive the corresponding rotating rollers 12 to rotate.

[0048] Through the above arrangement, when the front end of the in-box stacking equipment is widened by the lateral expansion assemblies 13 at both ends, the length of each lateral expansion assembly 13 can be reduced, thereby reducing the stress on the lateral expansion assembly 13 and increasing the stability of the lateral expansion assembly 13.

[0049] Specifically, compared with the case where only one end of the support body 11 is provided with the lateral expansion assembly 13, when both ends of the support body 11 are provided with the lateral expansion assemblies 13, the length of the lateral expansion assembly 13 needs to be only half when the same width is increased. When the lateral expansion assembly 13 is unfolded, the weight of the articles borne by each lateral expansion assembly 13 is reduced, and the stability of the lateral expansion assembly 13 is increased.

[0050] In order to convey the articles to the lateral expansion assemblies 13 at both ends of the support body 11, the application is provided with a plurality of independent first driving mechanisms. The first driving mechanism can be a motor structure arranged in the rotating roller, or a motor structure arranged on the support. When the application is used, after the conveying mechanism 21 outputs the articles to one of the roller groups, the first driving mechanisms on the lower side and the left side of the articles move synchronously, and the articles move to the left lateral expansion assembly 13 under the action of the rotating rollers 12, until the articles are arranged on the roller group on the left side of the output mechanism and the left lateral expansion assembly 13. Then, when the conveying mechanism 21 continues to output the articles to the roller group, the first driving mechanisms on the lower side and the right side of the articles move synchronously, so that the subsequent articles move to the right lateral expansion assembly 13, until the articles are arranged on the roller group on the right side of the output mechanism and the right lateral expansion assembly 13.

[0051] As an implementation, the bracket body 11 is provided with a push plate 14 on the side close to the conveying mechanism 21, and a pushing mechanism 141 for driving the push plate 14 to push the articles on the rotating roller 12 and the lateral expansion assembly 13, the push plate 14 comprises a push plate body 14 for pushing the articles on the rotating roller 12 and an expansion plate 15 for pushing the articles on the lateral expansion assembly 13, the expansion plate 15 is slidingly connected to the two ends of the push plate body 14, and the two ends of the push plate 14 are provided with fixing mechanisms for fixing the expansion plate 15 on the push plate 14.

[0052] Through the above arrangement, the width of the push plate 14 is adjusted by adjusting the position of the expansion plate 15 on the push plate body 14, so that the width of the push plate 14 is adapted to the width of the front end article carrying device of the in-box stacking equipment, so that the articles on the rotating roller 12 and the lateral expansion assembly 13 can be pushed out by the push plate 14 to be stacked.

[0053] Initially, the push plate is located above the side of the bracket body close to the conveying mechanism, after the conveying mechanism outputs the articles, the articles pass from the upper side of the push plate to the upper side of the rotating roller, and when the articles are arranged on the rotating roller 12 and the lateral expansion assembly 13, the pushing mechanism 141 drives the push plate 14 to move towards the articles, and when the push plate moves to the side of the bracket body away from the conveying mechanism, the push plate 14 pushes the articles off the rotating roller 12 and the lateral expansion assembly 13. The fixing mechanism can be a bolt, and the pushing mechanism 141 can be in the form of a pneumatic cylinder or a conveyor belt.

[0054] As an implementation, the bracket body 11 comprises two mutually parallel connecting beams 111, the connecting beams 111 are fixedly connected through connecting rods 112, the lateral expansion assembly 13 is arranged at the two ends of the connecting beams 111, the rotating rollers 12 are rotatably connected between the connecting beams 111, the rotating rollers 12 are arranged in sequence along the extension direction of the connecting beams 111, the axis of the rotating rollers 12 is perpendicular to the extension direction of the connecting beams 111, and the upper side of the connecting beams 111 is lower than the upper edge of the rotating rollers 12. The push plate 14 is higher than the connecting beams, so that the push plate can move from the upper side of one connecting beam to the upper side of the other connecting beam.

[0055] As an implementation, the lower side of the rotating roller 12 is provided with a connecting seat 113, the side of the connecting seat 113 away from the push plate 14 is fixedly connected with a plurality of first supporting rods 114 for supporting the articles pushed off from the rotating roller 12, the first supporting rods 114 are parallel to the rotating roller 12, and the first supporting rods 114 pass through the connecting beams 111 and are slidingly connected with the connecting beams 111, the outer side of the connecting beams 111 is provided with a reinforcing plate 115, and the ends of the first supporting rods 114 away from the connecting seat 113 are fixedly connected with the reinforcing plate 115, and the bracket body 11 is provided with a second driving mechanism 116 for driving the connecting seat 113 to move axially along the first supporting rods 114.

[0056] Through the above arrangement, the stability of the article stacking can be increased. The first supporting rods are arranged in parallel and spaced apart. The spacing of the first supporting rods is less than the width of the articles to be carried, so as to prevent the articles from falling from between the first supporting rods.

[0057] Specifically, after the articles are arranged on the rotating roller 12, the second driving mechanism 116 drives the connecting seat 113 to move, so that the first supporting rod 114 extends to one side of the support, and the pushing mechanism 141 drives the push plate 14 and pushes the articles on the rotating roller 12 to fall onto the first supporting rod 114, as shown in Figure 4 and Figure 5 Then the pushing mechanism 141 reversely drives the push plate 14, and the push plate 14 retreats to the initial position, ready to push the next row of articles. When the lower side of the first supporting rod 114 has been stacked with articles, the second driving mechanism 116 reversely drives the connecting seat 113, and the first supporting rod 114 retreats to the initial position. Under the extrusion of the connecting beam, the articles fall from the first supporting rod 114 to the lower side of the articles, and in this process, the lower side of the articles is basically subjected to only a vertical impact force, thereby ensuring the stability of the lower side of the articles. The second driving mechanism 116 can be in the form of a transmission belt or a pneumatic cylinder.

[0058] As an implementation manner, the transverse expansion assembly 13 comprises a first rotating shaft 131 vertically penetrating through the connecting beam 111 and rotationally connected with the connecting beam 111, and a supporting assembly 132 fixedly connected with the first rotating shaft 131 and used for supporting the articles, and the support body 11 is provided with a first adjusting mechanism used for driving the first rotating shaft 131 to rotate.

[0059] When the first adjusting mechanism drives the first rotating shaft 131 to rotate, the first rotating shaft 131 drives the supporting assembly 132 to rotate around the axis of the first rotating shaft 131. When the supporting assembly 132 is lowered, the width of the application is smaller, and when the supporting assembly 132 is rotated to the horizontal position, the width of the application is maximum.

[0060] As an implementation manner, one end of the first rotating shaft 131 is fixedly connected with a first pushing rod 134, and the first adjusting mechanism comprises a first electric cylinder 133, one end of the first electric cylinder 133 is rotationally connected with the connecting beam 111, and the other end of the first electric cylinder 133 is rotationally connected with the first pushing rod 134.

[0061] Through the above arrangement, the rotation of the first rotating shaft 131 can be realized through the extension and retraction of the first electric cylinder 133.

[0062] As an implementation form, the support assembly 132 comprises two parallel connecting plates 1321, a plurality of first support rollers 1322 rotatably connected between the connecting plates 1321, the first support rollers 1322 are arranged in sequence along the extension direction of the connecting plates 1321, the first support rollers 1322 are perpendicular to the connecting plates 1321 and parallel to the first rotating shaft 131, one end of the connecting plate 1321 and one end of the other connecting plate 1321 are fixedly connected with the first rotating shaft 131, and one end of the connecting plate 1321 away from the first rotating shaft 131 is fixedly connected with a limiting plate 1323 for preventing the articles from falling.

[0063] Through the above arrangement, when the articles move to the support assembly 132, the first support rollers 1322 support the articles, and when the first support rollers 1322 and the connecting plates 1321 are rotatably connected, the resistance of the articles moving transversely on the support assembly 132 is small.

The push plate 14 is higher than the connecting beam, so that the push plate can be moved from the upper side of one connecting beam to the upper side of the other connecting beam.

[0069] As an implementation form, the lower side of the rotating roller 12 is provided with a connecting seat 113, the side of the connecting seat 113 away from the push plate 14 is fixedly connected with a plurality of first supporting rods 114 for supporting the articles pushed off from the rotating roller 12, the first supporting rods 114 are parallel to the rotating roller 12, and the first supporting rods 114 pass through the connecting beams 111 and are slidingly connected with the connecting beams 111.
