Description

Technical Field

[0001] The present invention relates to the technical field of sliver cans conveyors, and particularly to an ultra-low pulley sliver shuttle car. Background Art

[0002] In the cotton spinning industry, when cotton becomes in a sliver state, sliver cans are usually used for storage. When the sliver cans are filled with sliver in a sliver state, the filled sliver cans need to be transported. In the prior art, for example, a Chinese utility model patent with the patent number ZL202020370546.7 discloses a sliver can ferry car, which includes a vehicle body. Two parallel first crossbars are fixedly connected to one side of the vehicle body. A second crossbar is fixedly connected to one side of the vehicle body. The second crossbar is arranged between the two first crossbars and is parallel to the first crossbars. A linear guide rail is fixedly connected to the upper side of the second crossbar. A slider is slidably connected to the linear guide rail. A base is fixedly connected to the upper side of the slider. Two swing rods are hinged to the base. A push-pull device for driving the slider to reciprocate along the linear guide rail is further provided on one side of the slider. Such equipment can transport at most two sliver cans at a time, with low efficiency.

[0003] In order to improve efficiency, for example, a Chinese utility model patent with the patent number ZL202120993665.2 discloses a shelf track system for a sliver can conveying four-way shuttle car, including: a full sliver can temporary storage area of a drawing frame and a corresponding empty sliver can temporary storage area of the drawing frame, in which shelf tracks for the operation of the sliver can conveying four-way shuttle car are respectively arranged in parallel. Shelves are installed on both sides of the shelf tracks; a sliver can temporary storage area of a roving frame, which is provided with a plurality of working channels, full sliver can standby channels and empty channels. Shelf tracks for the operation of the sliver can conveying four-way shuttle car are respectively arranged on the working channels, full sliver can standby channels and empty channels. Shelves are installed on both sides of the shelf tracks; and an intermediate reversing area, which is provided with an intermediate reversing track for the reversing operation of the sliver can conveying four-way shuttle car. The shelf tracks of the full sliver can temporary storage area of the drawing frame and the empty sliver can temporary storage area of the drawing frame are connected to one side of the intermediate reversing track; the shelf tracks of the working channels, full sliver can standby channels and empty channels are connected to the other side of the intermediate reversing track.

[0004] Although the above shelf track system effectively improves the transportation efficiency of sliver cans, since its transportation of sliver cans depends on a four-way shuttle car, and a four-way shuttle car can transport at most two or three sliver cans at a time, and the shelf tracks cannot orderly carry too many shuttle cars to work normally at the same time, so the overall transportation efficiency still needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the above prior art, and provide an ultra-low pulley sliver shuttle car, which can greatly improve the transportation efficiency of sliver cans.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] The ultra-low-position pulley shuttle comprises a travel guide rail, a vehicle body arranged on the travel guide rail, and a travel mechanism arranged between the vehicle body and the guide rail; a plurality of cargo channels are sequentially distributed on the vehicle body along the length direction of the guide rail, and a hook-drum mechanism is provided on the side of each cargo channel; the hook-drum mechanism comprises a telescopic component moving along the loading and unloading direction of the cargo channel, and a swing component cooperating with the output end of the telescopic component; the swing component has a plurality of groups of hook plates distributed along the telescopic direction of the telescopic component.

[0008] The working principle of the present invention is as follows: the swing component is in the initial state or through swinging, so that the multiple groups of hook plates are in an avoidance state, that is, they do not extend into the cargo channel (generally they can be facing upward or downward); then the telescopic component is actuated to drive the multiple groups of hook plates to extend a stroke outward along the cargo channel to the side of the external can, and the position of the first group of hook plates close to the outside corresponds to the two sides of a can; then the swing component is actuated to make the first group of hook plates swing to the two sides of the can, in a clamping state; then the telescopic component is reset to drive the hook plates and the cans hooked by the hook plates to move a stroke into the cargo channel; repeat the above actions, and in the second round of actions, the first group of hook plates will hook a new can outside, and the second group of hook plates will hook the first can already in the cargo channel, so as to move together a stroke into the cargo channel; until the first can is hooked by the innermost group of hook plates and hooked to the innermost side of the cargo channel; at this point, the entire loading process is completed; and multiple cargo channels can work synchronously to quickly complete the loading of a large number of cans. Then, the whole vehicle body is moved along the travel rail through the traveling mechanism. When it reaches the destination, the reverse action of the above action is performed to gradually complete the unloading of the strip cans.

[0009] As a preferred embodiment of the present invention, the telescopic assembly includes a telescopic guide rail, a guide rail slide, a cylinder, and an active paddle connecting the guide rail slide and the cylinder output end; the active paddle cooperates with the swing assembly. The telescopic assembly provides output power through the cylinder, provides accurate guidance through the telescopic guide rail and the guide rail slide, and drives the extension and retraction of the hook plate in the swing assembly through the active paddle.

[0010] As a preferred embodiment of the present invention, the swing assembly includes a swing motor, a swivel arm connected to the output end of the swing motor, and a swing frame connected to the swivel arm in a circumferentially limited sliding manner; a plurality of groups of hook plates are sequentially arranged on the swing frame along the length direction of the swing frame, and a passive paddle plate cooperating with the active paddle plate is arranged on the swing frame. The swing assembly is connected to the swivel arm in a circumferentially limited sliding manner, so as to simultaneously realize the swing frame swinging with the rotation of the swivel arm and moving along the length direction of the swivel arm.

[0011] As a preferred embodiment of the present invention, the active paddle plate is provided with a paddle groove perpendicular to its moving direction, and the passive paddle plate has an arc-shaped edge inserted into the paddle groove, so as to maintain the cooperation between the active paddle plate and the passive paddle plate without affecting the rotation of the passive paddle plate, that is, the rotation of the swing frame.

[0012] As a preferred embodiment of the present invention, a sliding connection assembly is provided between the swivel arm and the swing frame, and slide grooves are provided on opposite sides of the swivel arm. The sliding connection assembly includes two sliders, two bent plates, and a connecting plate. The two sliders are respectively matched with two slide grooves, and the two bent plates are respectively connected to the two sliders. The first ends of the two bent plates are connected to the swing frame, and the second ends of the two bent plates are connected to each other through the connecting plate. Since the weight of the swing frame needs to be supported by the swivel arm, a certain connection strength is required between the two, and at the same time, the sliding of the swing frame cannot be affected. The above structure effectively meets this requirement. The entire sliding connection assembly is embraced on the swivel arm by applying forces in opposite directions, and the connection strength is reliable. There is only a connection relationship between the slider and the slide groove between the swivel arm, which ensures normal sliding.

[0013] As a preferred embodiment of the present invention, the sliding connection components have at least two groups, and a counterweight shaft is provided between the connection plates of different sliding connection components to improve the connection stability and the movement stability.

[0014] As a preferred embodiment of the present invention, support frames are provided at both ends of the cylinder, and two rotating sleeves are provided on the support frame near the output end thereof, and grooves are provided in the circumference of the rotating sleeves. A support plate is provided on the rotating arm, and the support plate has an arc-shaped edge that simultaneously matches the grooves of the two rotating sleeves, so as to provide support for the middle part of the rotating arm through the support plate, thereby improving the structural stability; at the same time, it does not affect the normal rotation of the rotating arm.

[0015] As a preferred embodiment of the present invention, each group of the hook plates includes two hook plates, and the two hook plates are provided with a dial wheel on the opposite sides of one end away from the swing frame. That is, when the hook plates swing to the side of the can, there is no need to fully align them. The dial wheel can be used in conjunction with the curved side of the can itself to automatically adjust the position of the can to between each group of hook plates.

[0016] As a preferred embodiment of the present invention, the travel drive mechanism includes a supporting travel wheel, a travel motor, a drive shaft transmission-connected to the output end of the travel motor, and a driving travel wheel transmission-connected to the drive shaft; the supporting travel wheel and the driving travel wheel are circumferentially provided with guide grooves matching the travel guide rails to ensure the stability of the cooperation between the travel wheel and the travel guide rail, while increasing the friction between the driving travel wheel and the travel guide rail to ensure the reliability of the travel power.

[0017] As a preferred embodiment of the present invention, at both ends of the vehicle body in the moving direction, at least one of a buffer seat, a photoelectric switch, and a micro switch is provided to ensure the stability and safety of the movement of the vehicle body.

[0018] The advantages of the present invention are as follows:

[0019] 1. It can transfer a large number of cans simultaneously, greatly improving the efficiency of can transfer.

[0020] 2. The cooperation structure of the dial plate between the telescopic component and the swing component takes into account the telescoping and swinging of the hook plate, realizing a step-by-step can-hooking action.

[0021] 3. The sliding connection component ensures the stable connection between the rotary arm and the swing frame, while avoiding affecting the normal sliding of the swing frame.

[0022] 4. The cooperation between the support plate and the rotary sleeve provides effective support for the rotary arm in the middle, ensuring the stability of the equipment operation.

[0023] 5. The setting of the dial wheel at the end of the hook plate realizes the automatic adjustment of the position of the hook plate for the can, improving the smoothness of the equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0031] As Figures 1-3As shown, the present invention provides an ultra-low-position pulley can shuttle vehicle, including a travel guide rail 1, a vehicle body 3 for carrying a can 2, a plurality of groups of supporting travel wheels are arranged at the bottom of the vehicle body 3, a travel motor 41 is arranged at one end of the vehicle body 3, the output end of the travel motor is connected to a drive shaft 42 through a sprocket chain transmission, and the two ends of the drive shaft 42 close to the side of the vehicle body 3 are connected to driving travel wheels 43 through a gear set transmission, and the driving travel wheels are also arranged at the bottom of the vehicle body 3, and cooperate with the travel guide rail 1. In addition, guide grooves are arranged on the circumference of the supporting travel wheels and the driving travel wheels, and the travel guide rail 1 is a structure with a raised middle part to ensure the stability of the cooperation between the travel wheels and the travel guide rail, and at the same time, the friction between the driving travel wheels and the travel guide rail is improved to ensure the reliability of the travel power. In order to ensure the accuracy and safety of the vehicle moving distance, a buffer seat 5 is provided on the ground at both ends of the moving range of the vehicle body 3, a photoelectric switch 61 and a micro switch 71 are provided at the front and rear ends of the vehicle body 3, and a detection plate 62 cooperating with the photoelectric switch and a collision plate 72 cooperating with the micro switch 71 are provided on the corresponding ground.

[0032] The above structure is used to realize the movement of the entire vehicle body to transfer the cans carried on the vehicle body. Next, the structure on the vehicle body for automatically loading and unloading cans is introduced:

[0033] like Figures 4-6 As shown, the surface of the vehicle body 3 has a plurality of crossbeams 8 arranged parallel and at intervals along its moving direction, and a cargo channel 9 is formed between adjacent crossbeams 8, that is, the direction of the cargo channel 9 is perpendicular to the moving direction of the vehicle body, and a hook barrel mechanism is provided on the crossbeam on the same side of each cargo channel 9, and a partition 81 is provided on the side of each crossbeam 8 adjacent to the cargo channel to avoid interference with the cans and ensure that the cans can smoothly enter and exit the cargo channel. The hook barrel mechanism mainly includes a telescopic component and a swing component, the telescopic component is used to provide power for the cans to enter and exit the cargo channel, and the swing component is used to switch the coordination or avoidance relationship between the entire mechanism and the cans.

[0034] The telescopic assembly includes a telescopic guide rail 101, a guide rail slide 102, a cylinder 103, and an active shift plate 104 connecting the guide rail slide 102 and the output end of the cylinder 103. The telescopic guide rail 101 stands on the crossbeam 8, that is, the groove of the telescopic guide rail faces the side; the cylinder 103 is installed on the crossbeam 8 through the support frames 105 at both ends, and a shift groove perpendicular to the cylinder telescopic direction is opened on the upper end of the active shift plate 104. For the sake of travel safety, proximity switches 1061 are provided on the crossbeam 8 at both ends of the moving path of the active shift plate 104, and a trigger plate 1062 is bent out on the active shift plate 104 accordingly.

[0035] The swing assembly includes a swing motor 111, a slewing arm 112, a swing frame 113, a passive shift plate 114, and a sliding connection assembly 115. Among them, both ends of the slewing arm 112 are provided with a rotating shaft, and are supported and installed by a bearing seat plate 116 and a bearing 117 installed on the crossbeam 8. The rotating shaft at one end is connected to the swing motor 111 arranged on the crossbeam 8 through a sprocket chain assembly to realize the rotation of the slewing arm 112. The swing frame 113 is connected to the slewing arm 112 through a sliding connection assembly 115 with a circumferential limit, that is, the swing frame 113 can rotate synchronously with the slewing arm 112 and can slide along the length direction of the slewing arm. The passive shift plate 114 is arranged on the sliding connection assembly 115 and has an arc-shaped edge inserted into the shift groove, so as to always keep the cooperation with the shift groove of the active shift plate 104 during the rotation process.

[0036] Specifically, the swivel arm 112 is composed of two guide rails connected in opposite directions, that is, the opposite sides of the swivel arm 112 are provided with slide grooves 1121, and the sliding connection assembly 115 includes two sliders 1151, two bending plates 1152, and a connecting plate 1153. The bending plate 1151 includes a main body and two bending parts perpendicular to the same side of the two ends of the main body; the two sliders 1151 are respectively matched with the two slide grooves 1121, the main bodies of the two bending plates 1152 are respectively connected to the two sliders 1151, the first end bending parts of the two bending plates 1151 are connected to the swing frame 113, and the second end bending parts of the two bending plates 1151 are connected to each other through the connecting plate 1153. Considering the stability of the connection, the sliding connection assembly 115 has two groups, and a counterweight shaft 1154 is also connected between the connecting plates 1153 of the two groups of assemblies to improve the stability of the swing of the swing frame. One of the bending plates in the sliding connection assembly for setting the passive shift plate 114 also has a bending portion perpendicular to the side of the main body, and the passive shift plate 114 is installed on the two bending portions of the side.

[0037] In addition, considering the long length of the swivel arm 112, if it is supported only by the bearing seat plates 116 at both ends, the middle part may be deformed, so a support plate 1181 is provided in the middle part of the swivel arm 112, and two swivel sleeves 1182 are provided on the support frame 105 near the output end of the cylinder 103. The circumference of the swivel sleeve 1182 is provided with a groove, and the support plate 1181 has an arc edge that simultaneously contacts the grooves of the two swivel sleeves 1182, so as to provide stable support while not affecting the swing of the support plate 1181 with the swing frame 113. In addition, for the consideration of the accuracy of the installation position of the support plate 1181, the support plate 1181 is matched with the two slide grooves 1121 of the swivel arm through the two connected adjustment sliders 1183, so as to facilitate the adjustment of the support plate position during installation, and when the support plate is matched with the two swivel sleeves, its position will be fixed. In addition, a hole for the counterweight shaft 1154 to pass through is also opened on the support plate 1181.

[0038] The swing frame 113 specifically includes a square tube 1131 and multiple groups of hook plates spaced apart on the same side of the square tube 1131. Each group of hook plates includes two hook plates 1132 to jointly clamp the bobbin. Moreover, on the opposite sides of the ends of the two hook plates 1132 away from the square tube 1131, there are pulley wheels 1133 respectively. That is, when the hook plates swing to the side of the bobbin, it is not necessary to be completely aligned. The pulley wheels 1133 can cooperate with the arc-shaped side of the bobbin itself to automatically adjust the position of the bobbin between each group of hook plates. In order to prevent the pulley wheels from damaging the bobbin, rubber sleeves are provided on the pulley wheels.

[0039] In summary, the working principle of this shuttle car is as follows: In the initial state or through swinging, the swing assembly makes multiple groups of hook plates face upward, that is, they will not interfere with the bobbins in the external cargo channel direction; then the telescopic assembly acts to drive the swing frame to extend outward along the rotary arm by one stroke to the side of the external bobbin, and make the position of the first group of hook plates close to the outside correspond to both sides of a bobbin; then the swing assembly acts to make the first group of hook plates swing to both sides of the bobbin to be in a clamped state; subsequently, the telescopic assembly resets to drive the hook plates and the bobbins hooked by the hook plates to move inward by one stroke into the cargo channel; repeat the above actions. In the second round of actions, the first group of hook plates will hook a new external bobbin, and the second group of hook plates will hook the first bobbin already in the cargo channel, and they will jointly move inward by one stroke into the cargo channel; until the first bobbin is hooked by the innermost group of hook plates and hooked to the innermost side of the cargo channel; thus, the entire loading process is completed; and multiple cargo channels can work synchronously to quickly complete the loading of a large number of bobbins. Then, through the traveling mechanism, the entire vehicle body is moved along the traveling guide rail. After reaching the destination, in the reverse direction of the above actions, the unloading of the bobbins is gradually completed.
