Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a short-side packing flat pusher. Background Art

[0002] A packing machine, also known as a strapping machine, a banding machine or a bundling machine, uses a strapping band to strap products or packages, then tightens and combines the two ends by means of heat fusion bonding with a hot head. The function of the packing machine is to reinforce the packaged articles so that the articles will not scatter during handling and storage due to insecure strapping, and at the same time, the strapping should be neat and beautiful.

[0003] The existing packing method generally has roller conveyors on both the front and rear sides of the packing machine. After the packages are conveyed to a specific position by the roller conveyors, the packing machine is then manually started or automatically started after identifying the position of the packages with the help of an industrial camera, a sensor, etc. However, the response efficiency of manual start is relatively low, which affects the packing efficiency; although using an industrial camera can improve the response efficiency, the cost is relatively high; using a sensor has a low cost, but its control logic generally can only be applied to relatively short packages (for example, identifying the position of the package through one sensor and only strapping and packing the middle part of the package. Or using two sensors to identify the positions of both ends of the package respectively and strapping and packing both ends of the package), and it cannot be adapted to packages that require three or more strappings. And when the existing roller conveyor stops conveying the package, the package is likely to continue to move under the action of inertia, affecting the packing position accuracy, and this situation also seriously restricts the packing efficiency.

[0004] Therefore, we have designed a short-side packing flat pusher. Summary of the Utility Model

[0005] In order to overcome the deficiencies in the background art, the utility model discloses a short-side packing flat pusher.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A short-side packing flat pusher, comprising:

[0008] A frame, arranged at the tail side of the packing machine, and conveyor roller groups are arranged on both lateral sides above the frame;

[0009] A lifting baffle, slidably connected to the position between the conveyor roller groups on both sides of the frame, and blocking the package by the rising or falling of the baffle of the lifting baffle to eliminate the inertial displacement of the package or release the movement of the package;

[0010] A driving device, used to drive the lifting baffle to move longitudinally along the frame.

[0011] Further, the lifting baffle includes:

[0012] The sliding carriage is horizontally slidably connected to the inner side of the frame;

[0013] The lifting cylinder is vertically arranged on one side of the sliding carriage corresponding to the bundling machine;

[0014] Wherein, the baffle is vertically slidably connected to one side of the sliding carriage corresponding to the bundling machine, and is correspondingly connected to the telescopic end of the lifting cylinder.

[0015] Further, an extension part is arranged on one side of the top of the baffle corresponding to the bundling machine to facilitate adapting to bundling machines of different lengths.

[0016] Further, a trigger switch is arranged on one side of the top of the baffle corresponding to the bundling machine, and the trigger switch is electrically connected to the bundling machine for starting the operation of the bundling machine.

[0017] Further, the driving device includes:

[0018] The rack is longitudinally arranged on the inner side of the frame;

[0019] The servo motor has its fixed part installed on the lifting baffle, and a driving gear meshing with the rack is arranged on the output shaft.

[0020] Further, the top of the frame is a rectangular frame, and two installation beams spanning it longitudinally are symmetrically arranged inside the rectangular frame, and the conveying roller groups are arranged between the installation beams and the corresponding side edges of the rectangular frame.

[0021] Further, the rollers in the conveying roller groups on both sides are arranged opposite to or staggered with each other.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The conveying roller groups are arranged at intervals symmetrically, providing a gradient-free moving space for the lifting baffle, realizing accurate adjustment of the blocking position according to the length of the packaged goods, and cooperating with the bundling machine to achieve multiple bundling operations;

[0024] Through the longitudinal movement control of the lifting baffle, it can timely block and eliminate the inertial displacement of the packaged goods when they are conveyed to the preset position, ensuring that the packaged goods are stably docked at the predetermined position, thus significantly improving the bundling position accuracy of the bundling machine and avoiding the problem of repeated adjustment caused by position deviation;

[0025] 3. The linkage design of the lifting baffle and the packing machine control system triggered by a switch enables the automatic triggering of the packing machine when the packaged item reaches the preset position, eliminating the need for manual intervention. Compared with relying on high-cost industrial cameras or complex sensor systems, the coordinated control of the trigger switch and the mechanical structure simplifies the control logic, reduces the hardware cost, and balances economy and technological advancement. At the same time, it breaks through the limitation of traditional sensor solutions that only support single or double strapping, meeting the process requirements of complex packaging scenarios.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating the orientation or position relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model; it should be understood that if there are terms such as "end", "side", "end part", "side part", "transverse", "longitudinal", etc. indicating the orientation or position relationship, it is only corresponding to the length and width of the corresponding component, that is, the "end part" indicates the head and tail regions in the length direction of the corresponding component, and the "side part" indicates the head and tail regions in the width direction of the corresponding component; it is for the convenience of describing the present utility model rather than indicating or implying that the device or element referred to must have a specific orientation.

[0036] Embodiment 1, in combination with the attached Figure 1-7 , a short-side packing and flat-pushing machine, comprising a frame 1, a lifting baffle 2 and a driving device 3.

[0037] In combination with the attached Figure 3 , the top of the frame 1 is of a rectangular frame 12 structure, and longitudinal installation beams 13 are symmetrically arranged on both sides of the top. Transmission roller groups 11 are respectively installed between the installation beams 13 and the side edges of the rectangular frame 12.

[0038] It should be noted that: the above installation beam 13 is not just a longitudinal beam, but can also be other structural forms, as long as it can ensure the installation and fixation of the rollers in the transmission roller group 11, and no further elaboration will be made here.

[0039] Furthermore, the transmission roller group 11 is composed of a plurality of rollers evenly distributed at equal intervals along the longitudinal direction of the frame 1, and the adjacent rollers are in transmission cooperation. The rollers in the two transmission roller groups 11 are arranged oppositely. It should be noted that: the transmission roller group 11 also has a motor for driving the rollers to rotate.

[0040] In combination with the attached Figure 1-2 and Figures 4 - 7, the lifting baffle 2 comprises a sliding frame 21, a lifting cylinder 22 and a baffle 23. The sliding frame 21 is horizontally slidably connected between the installation beams 13 on the inner side of the frame 1 through a linear slide rail structure.

[0041] The lifting cylinder 22 is vertically fixed on one side of the sliding frame 21 close to the packing machine, and its telescopic end is connected to the baffle 23. The baffle 23 is vertically arranged and is slidably connected to the sliding frame 21 through a slide rail, and can rise or fall under the drive of the lifting cylinder 22. An extension part 231 is arranged on one side of the top of the baffle 23 close to the packing machine.

[0042] Specifically, the extension part 231 has a vertical section on the side corresponding to the packing machine, which fits and blocks the packaging piece to prevent it from being inserted into the packaging piece and causing damage to the packaging piece (such as a cardboard box).

[0043] As needed, the extension part 231 can be a metal plate with adjustable length, which is fixed to the baffle 23 by bolts to meet the requirements of balers with different widths. During specific use, the extension part 231 can be moved above the workbench of the baler.

[0044] In addition, in combination with the attached Figure 2 , a trigger switch 4 is also provided at the top of the baffle 23. Specifically, the trigger switch 4 is installed at the bottom of the extension part 231, and the trigger switch 4 is electrically connected to the control system of the baler. That is, when the package touches the baffle 23 (the vertical section of the extension part 231), the trigger switch 4 is triggered at this time to send a start signal to the baler to control the baler to start running. It should be noted that: the trigger switch 4 adopts the existing technology, and its specific structure and principle will not be described in detail here.

[0045] In combination with the attached Figure 4-5 , the driving device 3 includes a servo motor 32, a driving gear 33, and a rack 31 longitudinally fixed inside the machine frame 1. The servo motor 32 is fixed on the sliding frame 21, and its output shaft is coaxially connected to the driving gear 33. The driving gear 33 meshes with the rack 31 inside the machine frame 1. That is, by controlling the forward and reverse rotation of the servo motor 32, the driving gear 33 is moved along the rack 31, so as to drive the lifting baffle 2 to move precisely longitudinally along the machine frame 1 to adjust the blocking position of the baffle 23.

[0046] The working process, in combination with the attached Figure 8 , taking the three - stage bundling and packing of the package as an example:

[0047] First, the driving device 3 moves the lifting baffle 2 to the first packing position, and makes the package touch the baffle 23 (such as the upper figure in Figure 8 ), at this time the trigger switch 4 is triggered, and the baler packs the package for the first time; then the driving device 3 moves the lifting baffle 2 to the second packing position, at this time the package is conveyed by the conveyor roller group 11, when the package reaches the second packing preset position, the conveyor roller group 11 stops conveying, at this time the package touches the baffle 23 to eliminate its inertial displacement (such as the middle figure in Figure 8 ), and similarly the second bundling and packing of the package is completed; then the driving device 3 moves the lifting baffle 2 to the third packing position, at this time the package is conveyed by the conveyor roller group 11, when the package reaches the third packing preset position, the conveyor roller group 11 stops conveying, at this time the package touches the baffle 23 to eliminate its inertial displacement (such as the lower figure in Figure 8 ), and similarly the third bundling and packing of the package is completed; finally, the lifting cylinder 22 drives the baffle 23 to descend to a height lower than the bottom surface of the package, and at this time the conveyor roller group 11 conveys the package to the next process.

[0048] It should be noted that in the embodiment, another matching roller conveyor can also be arranged at the head end of the packing head for feeding operation.

[0049] Embodiment 2, in combination with the attached Figure 1-3 , a short-side packing and flat-pushing machine, which is different from Embodiment 1 in that: the servo motor 32 of the driving device 3 is replaced by a stepping motor, and a speed reducer is added between the rack 31 and the driving gear 33 to improve the accuracy and stability of position control. In addition, the extension part 231 of the baffle 23 adopts a telescopic design, and the length adjustment is realized through a cylinder or a telescopic sleeve to further meet the requirements of different specifications of packing machines.

[0050] In other embodiments, the rollers in the two conveyor roller groups 11 can also be arranged staggeredly.

[0051] In the example, the conveyor roller group 11 and the lifting baffle 2 can be started simultaneously, as long as it is ensured that the moving speed of the baffle 23 is greater than the conveying speed of the conveyor roller group 11 for the packaged items. For example, the conveyor roller group 11 can be controlled to stop conveying through a time relay when the lifting baffle 2 stops running. Specifically, the moving speed of the baffle 23 is A, the conveying speed of the conveyor roller group 11 for the packaged items is B, and the distance between two adjacent bundlings of the packaged items is L. At this time, the time T set by the time relay is T = L / B - L / A.

For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model; therefore, from any point of view, the above embodiments should be regarded as exemplary and non-limiting.
