Abstract
Description
Technical Field
[0001] This application relates to the field of material conveying technology, and in particular to a turning mechanism for a transfer trolley. Background Technology
[0002] In the freeze-drying process of food, the food needs to be transferred between different workstations, undergoing multiple steps such as traying, freeze-drying, and packaging. To improve the speed of food transfer, tracks are usually installed on the ceiling of the workshop, allowing the material racks for transporting food to move between multiple workstations via these tracks. To improve space utilization, multiple turning mechanisms are typically designed on the tracks, depending on the size of the workshop, so that materials can be switched to different tracks during transport.
[0003] A monorail conveyor, also known as a suspended conveyor, is a continuous conveying system that utilizes three-dimensional space. It consists of a track and multiple electric trolleys running on the track. Each trolley can be driven independently. It has a large single-unit conveying capacity and can use a long track to achieve long-distance conveying across workshops or factories. It is widely used in the automotive and telecommunications industries, as well as assembly lines and testing lines in factories and enterprises.
[0004] However, monorail conveyors generally only transport goods in a closed loop. The next electric trolley can only continue to work after the previous one has finished its transport work. This results in low efficiency and shortcomings in the transport process. Utility Model Content
[0005] In order to overcome the technical problems of monorail conveyors, this application provides a turning mechanism for a transfer trolley.
[0006] The technical solution adopted in this application for a turning mechanism for a transfer trolley is as follows:
[0007] A turning mechanism for a transfer trolley includes a conveying bracket, on which a straight conveying track and a turning transfer track are provided. An electric trolley is slidably mounted on the straight conveying track. A track-changing assembly is provided between the straight conveying track and the turning transfer track, and the track-changing assembly is used to move the electric trolley on the straight conveying track onto the turning transfer track.
[0008] By adopting the above technical solution, when the electric trolley at the front end of the conveying straight track needs to perform conveying work, the track changing component enables the electric trolley at the front end of the conveying straight track to slide onto the transfer curved track, and then the electric trolley at the rear end of the conveying straight track can continue to move forward, so that multiple electric trolleys on the conveying straight track can work separately, thereby improving the working efficiency of the electric trolleys.
[0009] Optionally, the track-changing assembly includes a track-changing bracket disposed on the conveying bracket, a track-changing plate slidably disposed on the track-changing bracket, a sliding member disposed on the track-changing bracket for driving the track-changing plate to slide, a connecting straight track and a track-changing curved track disposed on the track-changing plate, both ends of the connecting straight track are used to connect to the conveying straight track, the track-changing curved track is used to connect the conveying straight track and the transfer curved track, and only one of the connecting straight track and the track-changing curved track can be connected to the conveying straight track at any given time.
[0010] By adopting the above technical solution, when the electric trolley traveling on the straight conveying track changes track, the sliding component drives the track changing plate to slide, so that the connecting straight track is separated from the straight conveying track, until the track changing curved track connects the straight conveying track and the transfer curved track, and the electric trolley on the straight conveying track slides from the track changing curved track to the transfer curved track.
[0011] Optionally, the sliding component includes a push cylinder disposed on the track-changing bracket, the push cylinder being electrically connected to the control system, the track-changing plate being disposed on the piston rod of the push cylinder, and the track-changing bracket being provided with a guide rod whose axis is parallel to the piston rod axis of the push cylinder, the track-changing plate being slidably sleeved on the guide rod.
[0012] By adopting the above technical solution, the control system starts the push cylinder, which pushes the piston rod of the cylinder to extend. Under the restriction of the guide rod, the track changing plate drives the connecting straight track to separate from the conveying straight track, while at the same time connecting the track changing curved track with the conveying straight track.
[0013] Optionally, a sensor electrically connected to the control system is provided on the top of the conveying track, and the sensing end at the bottom of the sensor is used to sense the electric trolley.
[0014] By adopting the above technical solution, when the electric trolley triggers the sensor, the sensor feeds the signal back to the control system. The control system then determines whether to start the push cylinder based on the situation, thereby determining the material conveying position.
[0015] Optionally, a linear bearing is slidably disposed on the guide rod along its axial direction, and the linear bearing is disposed on the variable track plate.
[0016] By adopting the above technical solution, the linear bearing reduces the friction between the guide plate and the guide rod, which is beneficial for the smooth and rapid sliding of the guide plate.
[0017] Optionally, the conveying straight track includes multiple short straight tracks connected end to end, and adjacent short straight tracks can be detachably connected.
[0018] By adopting the above technical solution, workers can easily assemble the equipment according to the size of the factory, which is highly convenient in terms of operation.
[0019] Optionally, the transfer curve track includes a short curve track and a short curve straight track, and the short curve track and the short curve straight track are detachably connected.
[0020] By adopting the above technical solution, workers can replace short curved tracks of different sizes according to the actual needs of the factory.
[0021] Optionally, both the conveying straight track and the transfer curved track have an I-shaped cross-section, and the wheels of the electric trolley are engaged on both sides of the I-shaped conveying straight track.
[0022] By adopting the above technical solution, it is beneficial for the electric trolley to maintain stability during the transportation process.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When the electric trolley at the front end of the conveying straight track needs to perform conveying work, the track changing component enables the electric trolley at the front end of the conveying straight track to slide onto the transfer curved track, and then the electric trolley at the rear end of the conveying straight track can continue to move forward, so that multiple electric trolleys on the conveying straight track can work separately, thereby improving the working efficiency of the electric trolleys.
[0025] 2. When the electric trolley traveling on the straight conveying track changes track, the sliding component drives the track changing plate to slide, so that the connecting straight track is separated from the straight conveying track, until the track changing curved track connects the straight conveying track and the transfer curved track, and the electric trolley on the straight conveying track slides from the track changing curved track to the transfer curved track.
[0026] 3. When the electric trolley triggers the sensor, the sensor feeds the signal back to the control system. The control system then determines whether to activate the push cylinder based on the situation, thereby determining the material conveying position. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a turning mechanism for a transfer trolley.
[0034] Reference Figure 1 A turning mechanism for a transfer trolley includes a conveying support 1, on which a straight conveying track 2 and a curved transfer track 3, both with an I-shaped cross-section, are bolted. The length direction of the straight conveying track 2 is perpendicular to the length direction of the curved transfer track 3.
[0035] Reference Figure 1 and Figure 2 The conveying straight track 2 includes multiple short straight tracks 21 connected end to end, and two adjacent short straight tracks 21 are detachably connected. The transfer curved track 3 includes a short curved track 31 and a short curved straight track 32, and the short curved track 31 and the short curved straight track 32 are detachably connected.
[0036] Reference Figure 1 and Figure 2 An electric trolley 4 is slidably arranged on the conveying straight track 2. The wheels of the electric trolley 4 are stuck on both sides of the I-shaped conveying straight track 2. A sensor 6 electrically connected to the control system is bolted to the top of the conveying straight track 2. The sensing end at the bottom of the sensor 6 is used to sense the electric trolley 4.
[0037] Reference Figure 1 , Figure 2 and Figure 3 A track-changing assembly 5 is arranged between the straight conveying track 2 and the curved transfer track 3. The track-changing assembly 5 is used to slide the electric trolley 4 on the straight conveying track 2 onto the curved transfer track 3.
[0038] The electric trolley 4 slides along the conveying straight track 2. When the electric trolley 4 triggers the sensor 6, the sensor 6 feeds back the signal to the control system. The control system compares the signal with the information in the system memory. When it is not necessary to change the track of the electric trolley 4, the electric trolley 4 continues to slide along the length of the conveying straight track 2.
[0039] Reference Figure 3 and Figure 4The track-changing assembly 5 includes a track-changing bracket 51 bolted to the conveying bracket 1, a track-changing plate 52 horizontally slidably arranged on the track-changing bracket 51, a sliding member 53 for driving the track-changing plate 52 to slide on the track-changing bracket 51, and a connecting straight track 54 and a track-changing curved track 55 bolted to the track-changing plate 52.
[0040] Reference Figure 3 and Figure 4 Both ends of the connecting straight track 54 are used to connect to the short straight track 21, and the changing track curved track 55 is used to connect the conveying straight track 2 and the short curved track 31. Only one of the connecting straight track 54 and the changing track curved track 55 can be connected to the conveying straight track 2 at a time.
[0041] Reference Figure 3 and Figure 4 The sliding component 53 includes a push cylinder 531 bolted to the track changer bracket 51. The push cylinder 531 is electrically connected to the control system. The track changer plate 52 is bolted to the piston rod of the push cylinder 531. A guide rod 532 with an axis parallel to the piston rod axis of the push cylinder 531 is welded to the track changer bracket 51. A linear bearing 7 is slidably sleeved on the guide rod 532 along its axial direction. The linear bearing 7 is welded to the track changer plate 52.
[0042] When it is necessary to change the track of the electric trolley 4, the control system starts the push cylinder 531, which pushes the piston rod of the cylinder 531 to extend. Under the restriction of the guide rod 532, the track changing plate 52 drives the connecting straight track 54 away from the conveying straight track 2.
[0043] At the same time, the changing track plate 52 drives the changing track curved track 55 to continuously approach the conveying straight track 2 until the changing track curved track 55 connects with the conveying straight track 2. The electric trolley 4 on the conveying straight track 2 slides from the changing track curved track 55 to the transfer curved track 3, thereby enabling the electric trolley 4 to achieve the effect of separate transportation, thereby improving the transportation efficiency of the electric trolley 4.
[0044] The implementation principle of the turning mechanism of the transfer trolley in this application embodiment is as follows: the electric trolley 4 slides along the conveying straight track 2. When the electric trolley 4 triggers the sensor 6, the sensor 6 feeds back the signal to the control system. The control system compares the signal with the information in the system memory. When it is not necessary to change the track of the electric trolley 4, the electric trolley 4 continues to slide along the length direction of the conveying straight track 2.
[0045] When it is necessary to change the track of the electric trolley 4, the control system starts the push cylinder 531, which pushes the piston rod of the cylinder 531 to extend. Under the restriction of the guide rod 532, the track changing plate 52 drives the connecting straight track 54 away from the conveying straight track 2.
[0046] At the same time, the changing track plate 52 drives the changing track curved track 55 to continuously approach the conveying straight track 2 until the changing track curved track 55 connects with the conveying straight track 2. The electric trolley 4 on the conveying straight track 2 slides from the changing track curved track 55 to the transfer curved track 3, thereby enabling the electric trolley 4 to achieve the effect of separate transportation, thereby improving the transportation efficiency of the electric trolley 4.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
