The first driving device, the second driving device and the third driving device respectively pass through the transmission chain (not shown) and the sprocket of the roller 2 in the first roller group 31, the sprocket of the roller 2 in the second roller group 32 and the third The sprockets of the rollers 2 in the roller group 33 are connected in a driving manner. A stacking device and a binding device 4 are provided outside the first roller group 31 , and both the stacking device and the binding device 4 are in the prior art and will not be described here.

A first object sensor 51 , a second object sensor 52 and a third object sensor 53 are respectively provided at the rear end sides of the first roller group 31 , the second roller group 32 and the second roller group 33 . The first object sensor 51 , the second object sensor 52 and the third object sensor 53 are electrically connected to the roller table controller. The roller table controller controls the operation of the first roller group 31 , the second roller group 32 and the second roller group 33 .

A pallet is placed on the first roller group 3131. After the palletizing device stacks several beverage boxes full of beverage bottles located outside the palletizing conveying rollers on the pallet in turn, the binding device 4 stacks the palletized beverage boxes. to bundle. After the beverage boxes are bundled, the roller controller of the palletizing and conveying roller table controls the first drive device to drive the rollers 2 in the first roller group 3131 to rotate, and then bring the objects (that is, several palletized and bundled beverage boxes filled with beverages). ) from the first roller group 31 to the second roller group 32 . When the object is conveyed on the first roller set 31 to the tail end and is sensed by the first object sensor 51 , the roller table controller obtains the sensing signal of the first object sensor 51 and will immediately control the second roller set 32 The operation is started, and the first roller group 31 is controlled to stop running after a predetermined time delay. When the object is conveyed on the second roller set 32 to the end and is sensed by the second object sensor 52 , the roller table controller obtains the sensing signal of the second object sensor 52 and will immediately control the third roller set 33 The operation is started, and the second roller group 32 is controlled to stop running after a predetermined time delay. When the object is conveyed to the end of the third roller set 32 and sensed by the third object sensor 52, the roller table controller obtains the sensing signal of the third object sensor 52, and will immediately control the third roller set 33 Stop running, so that the object stops on the third roller group 33, waiting to be transported by the forklift. The predetermined delay time can be reasonably determined according to the length of the object and the running speed of the roller group. In this embodiment, the predetermined delay time is set to 2 seconds, which ensures that the objects are reliably transported from the upper roller set to the lower roller set.

An end baffle 6 is fixed at the end of the third roller group 33 , the end baffle 6 is also located between the tail ends of the two support plates 1 , and the top of the end baffle 6 protrudes from the top of the support plate 1 . , so that the end baffle 6 can intercept the objects at the end of the roller table and prevent the objects from running out of the roller table.

Both sides of the third roller group 33 are also provided with roller protection structures 7 for preventing the forklift from hitting the stacking conveying roller table during the process of moving objects. The anti-collision assembly 71 on one side and the side baffle 72 fixedly arranged on the other side of the rear end of the third roller group 33 are arranged opposite the anti-collision assembly 71 and the side baffle 72 . The anti-collision assembly 71 includes an anti-collision vertical plate 711 arranged on one side of the rear end of the third roller group 33 , an upper horizontal guard plate 712 located at the top of the anti-collision vertical plate 711 and folded into the roller channel laterally, and an anti-collision vertical plate 712 fixed on the ground and the anti-collision vertical plate 711 . The bottom end of the plate 711 is connected to the bottom plate 712, and the upper horizontal guard plate 712 extends to above the edge of the roller 2 in the third roller group 33 of the rollers. A tire block 714 is provided for intercepting the movement of the forklift wheels, and the side block 72 at least partially protrudes from the top of the third roller group 33 .

Specifically, the anti-collision vertical plate 711 is disposed on the outer side of one of the support plates 1 , and the anti-collision vertical plate 711 is fixed on the support plate 1 through the connecting plate 715 . The upper horizontal guard plate 712 is located at the top of the anti-collision vertical plate 711 and is vertically arranged with the anti-collision vertical plate 711, and the connection between the two is smoothly transitioned. The top is protected, and on the other hand, it is convenient for the forklift to judge the lifting height of the fork head, so that the fork head of the forklift can be accurately inserted into the pallet carrying the goods at one time. The bottom plate 713 and the bottom end of the anti-collision vertical plate 711 are vertically arranged, and the connection between the two is also smoothly transitioned. The bottom plate 713 is fixed on the ground by fixing bolts to ensure the overall stability of the anti-collision assembly 71 . The bottom plate 713 extends toward the outer side of the anti-collision vertical plate 711. The top surface of the bottom plate 713 is welded and fixed with a tire block 714 for blocking the movement of the forklift wheels. The tire block 714 is an inverted V-shaped steel rod. At that time, the forklift master can be reminded that the forklift has moved to the predetermined position, so as to prevent the forklift from hitting the stacking transfer roller table and stop the forklift. After the forklift is stopped, the fork head can be directly lifted at this time to lift the pallet on the roller to drive the pallet to move. Both sides of the anti-collision vertical plate 711 are provided with a side plate 716, and the side plate 716 is located above the bottom plate 713. The setting of the side plate 716 limits the lateral movement range of the forklift, and further improves the accuracy of the fork head inserting into the pallet. .

The side baffles 72 are fixed on the top surface of the other bracket plate 1 by the fixing rods 73.

The support plate 733 and the pressure plate 734 are tightened by bolts to realize the connection between the horizontal support rod 732 and the vertical support pile 731. fixed. One end of the horizontal support rod 732 is welded with the outer surface of the side baffle 72 to realize the fixing of the side baffle 72 . The side baffles 72 can resist the side of the pallet, effectively preventing the forklift from pushing the pallet laterally to move the pallet laterally so that the goods can be separated from the roller table, so as to ensure the stability of the goods during the handling process. Both ends of the side baffles 72 have guide parts bent to the outside of the roller table, which can ensure that when the goods move on the conveying channel, the guide parts have a correcting effect on the goods, so as not to slip out of the roller table.

The palletizing conveying roller table also includes a wire mesh for enclosing the working area of the palletizing device and the binding device 4 to form a protective ring 81 to prevent workers from accidentally breaking into the working area of the stacking device and the binding device 5 and being accidentally injured. In order to prevent the protective ring 81 formed by the wire mesh from affecting the movement of the object, the protective ring 81 is disconnected from both sides of the second roller group 32 to form an opening, and a human body sensor 82 for sensing people is arranged in the opening. The signal transmitting end 821 and the signal receiving end 822 are oppositely arranged on both sides of the stacking transmission roller, and the signal transmitting end 821 and the signal receiving end 822 are respectively installed on both sides of the opening formed by the wire mesh. The human body sensor 82 is electrically connected with the roller table controller. When the worker enters the encirclement formed by the wire mesh from the opening, the human body sensor 82 sends an induction signal to the roller table controller, and the roller table controller controls the entire stacking transmission roller table to stop running. , to ensure the safety of personnel.
