Technical Field

[0001] The utility model relates to the technical field of logistics sorting equipment, in particular to an inclined wheel fixing device and a middle-layer sorting roller assembly using the fixing device. Background Art

[0002] With the rapid development of e-commerce, the logistics industry has also grown rapidly. In this process, customers have higher and higher requirements for the utilization of space and the height reduction of equipment models. Thanks to this, in order to meet the application in double-layer conveyor lines and multi-layer conveyor lines, a top-lift right-angle cam transfer machine has appeared. However, since this type of transfer machine can only realize right-angle sorting relative to the conveying direction, the sorting conveyor can often only be set vertically to the conveyor line, resulting in the waste of space on both sides of the sorting conveyor. Therefore, the conveyor line using this type of transfer machine still has room for improvement in space utilization. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an inclined wheel fixing device which can be modified on the basis of a jacking type right-angle cam transfer machine to improve the space utilization rate.

[0004] The utility model adopts the following technical solutions:

[0005] The utility model provides an inclined wheel fixing device, comprising a strip cross brace, an inclined wheel bottom plate and an inclined wheel, the length of the strip cross brace is the same as the length of a sorting roller on a jacking type right-angle cam transfer machine, threaded mounting holes are respectively provided at both ends of the strip cross brace in the length direction, a plurality of inclined wheel bottom plates are installed in parallel and at intervals along the length direction of the strip cross brace, an inclined wheel is respectively arranged at both ends of each inclined wheel bottom plate, two inclined wheels on the inclined wheel bottom plate are symmetrically arranged on both sides of the strip cross brace, a lateral distance of each inclined wheel away from a center line of the inclined wheel bottom plate is half of a diameter of a sorting roller on the jacking type right-angle cam transfer machine, and a straight line where a conveying direction of each inclined wheel is located is arranged at the same acute angle to the strip cross brace.

[0008] Preferably, a connecting hole is provided at the bottom of the mounting groove, and a flat head bolt passes through the connecting hole and is screwed onto the bevel wheel bottom plate.

[0009] Preferably, the angle between the straight line where the conveying direction of each inclined wheel is located and the strip cross brace is 45°.

[0010] Preferably, the outer peripheral surface of the bevel wheel is coated with a wear-resistant colloid layer.

[0011] The utility model also provides a middle-layer sorting roller assembly, including a frame and the above-mentioned inclined wheel fixing device, a plurality of bearings are installed at intervals at the bottom of the frame, the bearings can rotatably abut against the cam, a plurality of inclined wheel fixing devices are threadedly fastened to the frame in parallel and at equal intervals, and a driving device in the frame drives all the inclined wheels to rotate synchronously.

[0012] Preferably, the driving device includes an electric roller and a driven roller, and an electric roller and multiple driven rollers are arranged in parallel and spaced apart in the frame. The electric roller and a driven roller close to the electric roller and two adjacent driven rollers are rotated synchronously through a multi-V belt, and each driven roller drives a whole row of inclined wheels on one side of the width direction of the strip cross brace to rotate synchronously through a round belt.

[0013] Preferably, the outer circumferential surface of the driven roller is provided with a plurality of first circumferentially concave grooves spaced axially, the outer circumferential surface of the bevel wheel is circumferentially concave inwardly at the middle position to form a second circumferential groove, the inner wall of one side of the circular belt is clamped in the first circumferential groove, and the inner wall of the other side is clamped in the second circumferential groove.

[0014] Preferably, the round belt is a PU round belt.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

Compared with the above-mentioned inclined wheel fixing device, the middle-layer sorting roller assembly of the utility model can obviously reduce the difficulty of modifying the traditional jacking-type right-angle cam transfer machine.

[0019] At the same time, since the middle-layer sorting roller assembly of the utility model adopts the above-mentioned inclined wheel fixing device, the overall thinness of the middle-layer sorting roller assembly can be achieved by means of the compact and efficient layout of the inclined wheels.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0036] See also Figure 1 The present embodiment provides an inclined wheel fixing device, comprising a strip cross brace 1, an inclined wheel base plate 2 and an inclined wheel 3. The length of the strip cross brace 1 is the same as the length of the sorting roller on the jacking type right-angle cam transfer machine. Threaded mounting holes 11 are respectively provided at both ends of the strip cross brace 1 in the length direction. Multiple inclined wheel base plates 2 are installed in parallel and spaced apart along the length direction of the strip cross brace 1. An inclined wheel 3 is respectively arranged at both ends of each inclined wheel base plate 2. The two inclined wheels 3 on the inclined wheel base plate 2 are symmetrically arranged on both sides of the strip cross brace 1. The lateral distance of each inclined wheel 3 away from the center line of the inclined wheel base plate 2 is half of the diameter of the sorting roller on the jacking type right-angle cam transfer machine, and the straight line where the conveying direction of each inclined wheel 3 is located is arranged at the same acute angle with the strip cross brace 1.

[0037] The inclined wheel fixing device of the present embodiment controls the length of the strip cross brace 1 to be the same as the length of the sorting roller on the jack-lift type right-angle cam transfer machine, and the lateral distance between each inclined wheel 3 and the center line of the inclined wheel bottom plate 2 is half the diameter of the sorting roller on the jack-lift type right-angle cam transfer machine. After a simple modification of the driving part of the sorting roller assembly in the middle layer of the conventional jack-lift type right-angle cam transfer machine, the original sorting roller can be replaced with the inclined wheel fixing device of the present embodiment, thereby transforming the original jack-lift type right-angle cam transfer machine into a jack-lift type oblique transfer machine.

[0038] The modified jack-up oblique transfer machine has the function of oblique sorting relative to the conveying direction. After being used on the conveyor line, the sorting conveyor is set accordingly. This allows the space on one side of the sorting conveyor to be effectively utilized, thereby improving the space utilization rate of the conveyor line.

[0039] It should be noted that the threaded mounting holes 11 on the strip cross brace 1 are used to connect and fix with the frame of the sorting roller assembly on the middle layer of the jacking type right-angle cam transfer machine. When the bevel wheel fixing device is installed to the position of the sorting roller, the bolts on the frame are screwed into the threaded mounting holes 11 of the strip cross brace 1; and the symmetrical arrangement of the two bevel wheels 3 on the bevel wheel base plate 2 relative to the strip cross brace 1 can ensure that the center of gravity of the two bevel wheels 3 is in the same straight running direction, ensuring that when the bevel wheels 3 are supporting and conveying parcels, the two bevel wheels 3 and the bevel wheel base plate 2 are subjected to balanced force, thereby preventing the bevel wheels 3 and the bevel wheel base plate 2 from being deformed and damaged due to uneven force.

[0040] Preferably, the strip cross brace 1 is a sheet metal part made by bending and welding.

[0041] Preferably, see Figure 2 The two ends of the bevel wheel bottom plate 2 are respectively installed with bevel wheel brackets 4, and the bevel wheel bracket 4 is provided with a mounting groove 41, and waist-shaped openings 43 are respectively opened on the vertical plates 42 on both sides of the mounting groove 41. The bevel wheel 3 is accommodated in the mounting groove 41, and the two ends of the rotating shaft on the bevel wheel 3 are respectively buckled in the waist-shaped openings 43 of the vertical plates 42 on both sides in an interference fit manner. When the bevel wheel 3 needs to be removed, it is only necessary to release the interference fit between the rotating shaft of the bevel wheel 3 and the waist-shaped openings 43 on the bevel wheel bracket 4.

[0042] Preferably, see Figure 3 A connection hole is formed at the bottom of the mounting groove 41, and a flat head bolt 5 passes through the connection hole and is screwed onto the bevel wheel bottom plate 2. Since the end of the flat head bolt 5 is relatively flat, the connection structure between the bevel wheel 3 and the bevel wheel bottom plate 2 is more compact and stable, and the overall height of the bevel wheel fixing device of this embodiment is relatively low.

[0043] Preferably, the angle between the straight line in the conveying direction of each inclined wheel 3 and the strip cross brace 1 is 45°, thereby ensuring that the parcels can be sorted out at a 45° angle relative to the conveying direction of the conveyor line, and ensuring that sufficient space can be reserved on both sides of the sorting conveyor for storing the sorted parcels.

[0044] Preferably, the outer peripheral surface of the inclined wheel 3 is coated with a wear-resistant colloid layer. The rubber coating treatment of the outer peripheral surface of the inclined wheel 3 can enhance the friction between the inclined wheel 3 and the parcel during transportation and sorting, thereby preventing slipping.

[0045] See also Figure 4The present embodiment further provides a middle-layer sorting roller assembly, including a frame 6 and the above-mentioned inclined wheel fixing device 7. A plurality of bearings are installed at intervals at the bottom of the frame 6, and the bearings can rotatably abut against the cam. A plurality of inclined wheel fixing devices 7 are threadedly fastened to the frame 6 in parallel and at equal intervals. The driving device in the frame 6 drives all the inclined wheels 3 to rotate synchronously.

[0046] When the middle-layer sorting roller assembly of the present embodiment is in use, the entire middle-layer sorting roller assembly on the conventional lifting-type right-angle cam transfer machine can be directly removed and replaced with the middle-layer sorting roller assembly of the present embodiment. The middle-layer sorting roller assembly can achieve lifting of the middle-layer sorting roller assembly by means of the contact between the bearing and the cam assembly of the lower layer of the lifting-type right-angle cam transfer machine. Compared with the above-mentioned inclined wheel fixing device 7, the middle-layer sorting roller assembly of the present embodiment can obviously reduce the difficulty of modifying the conventional lifting-type right-angle cam transfer machine.

[0047] At the same time, since the middle-layer sorting roller assembly of this embodiment adopts the above-mentioned inclined wheel fixing device 7, the overall thinning of the middle-layer sorting roller assembly can be achieved by means of the compact and efficient layout of the inclined wheel 3.

[0048] Preferably, see Figure 4 The driving device includes an electric roller 8 and a driven roller 9. An electric roller 8 and multiple driven rollers 9 are arranged in parallel and spaced apart in the frame 6. The electric roller 8 and a driven roller 9 close to the electric roller 8 and two adjacent driven rollers 9 are rotated synchronously through a multi-V belt. Each driven roller 9 drives a whole row of inclined wheels 3 on one side of the width direction of the strip cross brace 1 to rotate synchronously through a round belt.

[0049] Preferably, the outer circumferential surface of the driven roller 9 is provided with a plurality of first circumferentially inwardly concave grooves spaced in the axial direction, the outer circumferential surface of the bevel wheel 3 is circumferentially inwardly concave at the middle position to form a second circumferentially concave groove, the inner wall of one side of the round belt is clamped in the first circumferential groove, and the inner wall of the other side is clamped in the second circumferential groove. The provision of the first circumferential groove and the second circumferential groove can ensure the stable power transmission of the round belt to the bevel wheel 3, and prevent the round belt from running off the driven roller 9 or the bevel wheel 3 during the transmission process.

[0050] Preferably, the round belt is a PU round belt. PU is polyurethane. The round belt is a polyurethane round belt, which can ensure the stable transmission of the driven roller 9 to the bevel wheel 3 by virtue of the good elasticity, wear resistance and long service life of the polyurethane material.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
