Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a material tray gripping device. Background Technology

[0002] Newly produced cigarette filter rods need to be stored indoors to allow them to cure naturally for a certain period of time before they can be sent to the winding and splicing equipment for use. Therefore, in the filter rod production process, a storage warehouse is set up to store and cure the filter rods. The produced filter rods need to be "entered" into the storage warehouse for storage and curing, and then the cured filter rods are "taken out" from the storage warehouse for use.

[0003] Because filter rods are bulk materials, they need to be held in trays for storage in the storage warehouse. However, filter rods produced upstream and used downstream on the production line do not require trays. Therefore, a tray loading machine is used to load new filter rods into trays before they are stored in the warehouse. After a full tray leaves the warehouse, a tray unloading machine unloads the filter rods from the trays onto the production line. The existing tray loading machine typically works as follows: empty trays from the storage warehouse are input from the upper level of the tray loading machine at the filter rod storage station; after loading, full trays are output from the lower level of the tray loading machine to the filter rod storage station. Similarly, the tray unloading machine typically works as follows: full trays are input from the upper level of the tray unloading machine at the filter rod exit station; after unloading, empty trays are output from the lower level of the tray unloading machine to the filter rod exit station and then transported to the storage warehouse. Therefore, the filter rod entry and exit stations act as a bridge between the storage warehouse and the tray loading and unloading machines.

[0004] Currently, when filter rod in / out stations connect with the upper levels of loading / unloading machines, belt conveyors are generally used to transport the trays. The trays are in an unrestricted free state on the upper side of the belt conveyor, and swaying is prone to occur during the transport process, especially at the junction of the belt conveyor and the loading / unloading machine or the in / out station. Moreover, since the upper levels of different models of loading / unloading machines have different ground heights, when filter rod in / out stations in the same storage warehouse connect with the upper levels of different models of loading / unloading machines, the heights of the filter rod in / out stations and the upper levels of the loading / unloading machines are often inconsistent. The height difference between the two causes the belt conveyor used for docking to tilt, and the trays are prone to swaying or even tipping over during transport on this tilted surface, resulting in unstable tray transfer and transport. Utility Model Content

[0005] In view of this, this utility model provides a material tray gripping device to solve the problems of unstable material tray conveying, easy material tray tipping, and low conveying stability and reliability caused by the height difference between the filter rod inlet / outlet station and the loading / unloading machine, which leads to the non-horizontal docking conveying surface.

[0079] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0080] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0081] For ease of description in this embodiment, left, right, front, and back directions are defined, such as... Figure 1 As shown, left is Figure 1 The left side of the mid-frame platform 1 is [missing information], and the right side is [missing information]. Figure 1 The right side of the mid-frame platform 1, and the forward direction is... Figure 1 The direction perpendicular to the left and right of frame platform 1 and horizontally towards the outside of the drawing, with the rear direction being... Figure 1 The direction is perpendicular to the left and right direction of the frame platform 1 and horizontally towards the inside of the drawing. The definition of the direction is to illustrate the relative positional relationship between components and is not used to limit the actual position of the material tray gripping device during use.

[0082] Figure 1A schematic diagram of a material tray gripping device provided in an embodiment of this utility model is shown below. Figure 1 As shown, the device includes: a frame platform 1, a left transverse mechanism 2, a left lifting and clamping mechanism 3, a right transverse mechanism 4, a right lifting and clamping mechanism 5, and a drive mechanism 6. The top of the frame platform 1 covers the end of the material tray in / out station and the upper side of the upper material tray input end of the loading / unloading machine. The left transverse mechanism 2 and the right transverse mechanism 4 are symmetrically installed on the left and right inner frames of the frame platform 1. The left lifting and clamping mechanism 3 is connected to the left transverse mechanism 2, and the right lifting and clamping mechanism 5 is connected to the right transverse mechanism 4. The two ends of the drive mechanism 6 are connected to the upper ends of the left lifting and clamping mechanism 3 and the right lifting and clamping mechanism 5, respectively, and the drive mechanism 6 is used to drive the left lifting and clamping mechanism 3 and the right lifting and clamping mechanism 5 to lift simultaneously. The left lifting and clamping mechanism 3 and the right lifting and clamping mechanism 5 are configured to: reciprocate along the left transverse mechanism 2 and the right transverse mechanism 4 in the front-to-back direction, and, driven by the drive mechanism 6, clamp the material tray in the middle and move up and down vertically.

[0083] In this embodiment of the utility model, the left transverse mechanism 2 and the right transverse mechanism 4, the left lifting clamping mechanism 3 and the right lifting clamping mechanism 5 are symmetrical structures. The structure and function of the symmetrical left and right components are not significantly different. The following description will focus on the left transverse mechanism 2 and the left lifting clamping mechanism 3, while the right transverse mechanism 4 and the right lifting clamping mechanism 5 will not be described in detail.

[0084] The material tray gripping device provided by this utility model clamps and vertically lifts the material tray by setting up left and right lifting clamping mechanisms, and horizontally moves the left and right lifting clamping mechanisms by left and right lateral movement mechanisms. This enables the transfer of material trays between the inbound / outbound platform and the upper material tray input end of the loading / unloading machine, which have horizontal spacing and numerical height difference. During the transfer process, the material tray is kept in a horizontal state at all times, preventing tilting or even tipping over and spillage. Furthermore, the double-sided clamping conveying prevents shaking during tray handling, improving the stability and reliability of the material tray transport. In addition, the top of the frame platform covers the end of the inbound / outbound platform and the upper material tray input end of the loading / unloading machine, allowing for direct upgrades to existing production lines with a small footprint. Moreover, since the effective clamping distance between the left and right lifting clamping mechanisms is adjustable, it can be used with various material trays of different specifications, making the device highly versatile.

[0085] Preferably, such as Figure 1 As shown, the material tray gripping device of this utility model may also include a drag chain component 7 located above the drive mechanism 6. The drag chain component 7 consists of a drag chain groove and a first drag chain, and is usually connected to the frame platform 1 or other fixed frame. It plays a role in protecting the cable and air pipe during the forward and backward movement of the left transverse mechanism 2 and the right transverse mechanism 4.

[0086] Figure 2This is a schematic diagram of the framework platform in one embodiment of the present invention, as shown below. Figure 2 As shown, the frame platform 1 is a hollow frame, including: a left steel frame 11 welded from structural steel, two top beams 12, a right steel frame 13 welded from structural steel, and a bottom beam 14. To ensure the positional accuracy requirements between the installed components, the frame platform 1 can be a monolithic structure or divided into several parts with installation and mating requirements, connected by screws and washers.

[0087] Figure 3 This is a schematic diagram of the left lateral movement mechanism in one embodiment of the present invention, as shown below. Figure 3 As shown, the left lateral movement mechanism 2 includes:

[0088] The slide cylinder 21 is installed in the middle of the inner frame on the left side of the frame platform 1. The slide cylinder 21 includes a guide rod and a slide that is slidably connected to the guide rod. The guide rod extends in the front-rear direction of the frame platform 1. The slide cylinder 21 is equipped with a compensation unit, which is used to compensate for the connection deviation between the slide cylinder 21 and the relevant connecting parts.

[0089] A set of hydraulic buffer units 22 is provided on the front and rear sides of the guide rod of the slide cylinder 21. The hydraulic buffer units 22 are used to absorb the kinetic energy of the slide cylinder 21 during the positioning process to improve the positioning accuracy during lateral translation.

[0090] Linear guide unit 23: A set of linear guide units 23 parallel to the slide cylinder 21 is provided on the upper and lower sides of the slide cylinder 21. The linear guide unit 23 is fixedly connected to the inner frame of the left side of the frame platform 1; for example, when the structure of the frame unit 1 is as follows... Figure 2 In the structure shown, the linear guide unit 23 is connected to the left steel frame 11 with positioning.

[0091] Preferably, such as Figure 3 As shown, the linear guide unit 23 may include: two guide rail supports 231, a limiting block 232, a first slider 233, and a first linear guide 234. The two guide rail supports 231 are respectively fixedly installed on the front and rear sides of the inner frame on the left side of the frame platform 1; the first linear guide 234 is arranged parallel to the guide rod of the slide cylinder 21, and its two ends are connected to the guide rail supports 231; the first slider 233 is slidably connected to the first linear guide 234; the limiting block 232 is disposed on the first linear guide 234 to limit the sliding position of the first slider 233 on the first linear guide 234. The limiting block 232 is used in combination with two sets of hydraulic buffer units 22 on the slide cylinder 21. The hydraulic buffer units 22 absorb the kinetic energy of the slide cylinder 21 to reach its position. After the energy is consumed, the slider reaches the position of the limiting block 232. This allows for flexible adjustment of the stopping position of the connecting mechanism on the left transverse mechanism 2, improving positioning accuracy while ensuring no rebound occurs.

[0106] The second drag chain 347 has its movable end connected to the second drag chain bracket 345, and its fixed end fixed above the first cover 33. During the lifting and lowering process of the clamping mechanism 34, the cable and air pipe are wound up inside the second drag chain 347.

[0107] In some preferred embodiments, such as Figure 7 As shown, the slider body 323 also includes a first sensing piece 3235 disposed on the second upper limit seat 3233, and as... Figure 8As shown, the clamping mechanism 34 also includes a first detection bracket 344, and a second drag chain bracket 345 is connected to the first detection bracket 344. The lifting mechanism 32 also includes a first detection switch 343 installed on the first detection bracket 344.

The left and right ends of the crossbeam 61 are connected to the tops of the left lifting clamping mechanism 3 and the right lifting clamping mechanism 5, respectively. The crossbeam 61 is equipped with the wire-binding bracket 62 and the first drag chain movable end bracket 63. The motor base 68 is fixedly installed at the middle position of the lower surface of the crossbeam 61, and the hollow shaft motor 67 is fixed to the side of the motor base 68. Bearing seat units 65 are respectively provided on the left and right sides below the crossbeam 61. Two identical drive shafts 66 are installed through the hollow shaft motor 67 and the bearing seat unit 65, distributed on both sides of the hollow shaft motor 67. A sprocket 64 is installed at the end of the drive shaft 66 near the bearing seat unit 65.

[0111] The material tray gripping device of this utility model is usually installed at the end of the inbound and outbound stations. Figure 10 This is a schematic diagram showing the docking position of the material tray gripping device with the inbound / outbound platform and the loading / unloading machine in one embodiment of the present invention. Figure 10 As shown, firstly, the material tray 101 reaches the material tray gripping position 103 on the upper level 102 of the inbound / outbound platform. After the material tray gripping device 100 clamps the material tray 101 with the rubber-coated plates 346 on both sides and lifts it to a certain height, it moves laterally towards the loading and unloading machine 104 until the material tray 101 reaches the unloading position 105 and stops moving laterally. Then, the left and right lifting clamping mechanisms clamp the material tray 101 and begin to descend. When the material tray 101 contacts the conveyor belt surface on the upper level 106 of the loading and unloading machine, the left and right guide rod cylinders 342 simultaneously retract the extended guide rods, and the rubber-coated plates 326 release the material tray 101, completing the unloading. Then, the left and right lifting clamping mechanisms themselves lift and return to their original position towards the inbound / outbound platform, thus cyclically gripping and unloading the material trays, transferring the material trays on the upper level of the inbound / outbound platform to the upper level of the loading and unloading machine.
