Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco packaging equipment, and specifically relates to a pusher trolley that can precisely adjust the pitch. Background Technology

[0002] In the material handling stage of tobacco production, existing technologies mainly rely on fixed transfer trolleys or basic angle adjustment devices to transport materials such as tobacco frames and packs. In assembly line operations, the transfer trolley needs to cooperate with a mechanical gripper to transfer the tobacco packs.

[0003] Existing solutions mostly rely on basic mechanical structures to achieve angle adjustment. The basic transfer trolley cannot be finely adjusted, which may interfere with the mechanical gripper and cause transfer failure.

[0004] While some high-precision adjustable transfer trolley solutions exist, their complex structures and excessive costs make them unsuitable. Some high-end transfer equipment attempts to incorporate closed-loop control systems to improve adjustment accuracy, but this relies on multiple independent motors working in tandem, increasing the trolley's weight. Furthermore, the failure rate of precision transmission components increases in the high-dust environment of tobacco workshops. In addition, such equipment requires a guide system and a central controller, raising hardware costs by 3-5 times compared to traditional trolleys, making it difficult to promote in small and medium-sized tobacco factories. Utility Model Content

[0011] Based on the above-mentioned structure of a pusher trolley capable of precisely adjusting pitch, the support sub-plate is generally triangular in shape. The support sub-plate is vertically mounted on the support rear plate. The connection end between the support sub-plate and the support rear plate is the first end, and the end of the support sub-plate away from the support rear plate is the second end. The size of the support sub-plate gradually decreases from the first end to the second end.

[0012] Based on the above-mentioned structure of a pusher trolley capable of precisely adjusting pitch, the base includes a base side plate, a base top plate, a base rear plate, and a base front plate; the base rear plate and the base front plate are arranged opposite each other along the width direction of the supporting base plate, and the base rear plate and the base front plate are arranged perpendicular to the supporting base plate; the base side plate is arranged opposite each other along the length direction of the supporting base plate, and the base side plate front plate is arranged perpendicular to the supporting base plate; the base top plate is provided with the base side plate, the base rear plate, and the base front plate, so that the whole body forms a cavity structure.

[0013] Based on the above-mentioned structure of a pusher trolley that can precisely adjust the pitch, a support ear is provided at the front end of the base side plate. The support ear protrudes a predetermined distance away from the support base plate. A hinge hole is provided on the support ear, and the temporary storage cavity is hinged through the support ear and the connecting ear.

[0014] Based on the above-mentioned structure of a pusher trolley capable of precisely adjusting pitch, the support part includes a support handrail, a first crossbar, and a second crossbar; the first crossbar and the second crossbar are respectively disposed between the two support handrails, so that the two support handrails form a stable frame support structure; the first crossbar is disposed at the end between the two support handrails near the support back plate, and the second crossbar is disposed at the end between the support handrails away from the support back plate; a third crossbar is also disposed at the bottom position of the two support handrails.

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0031] Example 1

[0032] like Figures 1-6 As shown, this utility model provides a technical solution:

[0033] A pusher trolley capable of precisely adjusting pitch includes a moving part 1, a temporary storage part 2, a support part 3, an adjustment part 4, and a base 5; the support part 3 and the temporary storage part 2 are disposed on the upper end surface of the base 5, the moving part 1 is disposed on the lower end surface of the base 5, the temporary storage part 2 is hinged to the base 5, and the adjustment part 4 is disposed between the support part 3 and the temporary storage part 2.

[0034] Based on the above structure, this solution enables the entire pusher trolley to move quickly via the motion unit 1, facilitating rapid transport of cigarette pack materials by operators. Simultaneously, the temporary storage unit 2 is hinged to the motion unit 1, allowing for precise adjustment of the pitch angle of the temporary storage unit 2 under the action of the adjustment unit 4. This allows the temporary storage unit 2 to adapt to the space on the production line and adaptively adjust its pitch angle according to the structure of the mechanical gripper, enabling the mechanical gripper to efficiently unload materials. Furthermore, the adjustment unit 4 can quickly adjust the pitch angle, tilting the entire temporary storage unit 2 during transfer to prevent cigarette packs from falling. When cooperating with the mechanical gripper, it maintains a slight tilt to avoid interference.

[0035] As an example, the motion part 1 may include a support base plate 11 and a caster wheel 12. The support base plate 11 is generally rectangular in structure, and the caster wheel 12 is arranged along the four right-angle ends of the support base plate 11. A brake assembly 13 is provided on the caster wheel 12, and the brake assembly 13 is hinged to the housing of the caster wheel 12.

[0036] Based on the above structure, the entire support base plate 11 is set as a rectangular structure, which facilitates its embedded sliding into the assembly line structure and ensures that the overall moving part 1 has a certain area, so that the adjacent universal wheels 12 can be spaced a certain distance apart, making the overall movement more stable. At the same time, a brake assembly 13 is set, which can brake the rollers when the moving part 1 moves to the predetermined position, ensuring the stability of the temporary storage part 2 when receiving cigarette boxes.

[0037] As an example, the temporary storage section 2 may include a supporting bottom frame 21, a first side plate 22, a second side plate 23, and a supporting back plate 24; the first side plate 22 and the second side plate 23 are symmetrically arranged on both sides of the supporting back plate 24, the supporting bottom frame 21 is arranged at the bottom of the supporting back plate 24, and the supporting bottom frame 21, the first side plate 22, the second side plate 23, and the supporting back plate 24 form an open structure.

[0038] The supporting base frame 21 may include a supporting sub-plate 211, a connecting ear 212, and a supporting rear plate 213; the connecting ears 212 are symmetrically arranged at both ends of the supporting rear plate 213, and the supporting sub-plates 211 are spaced apart along the length of the supporting rear plate 213, with the supporting sub-plates 211 near the connecting ears 212 spaced apart from the connecting ears 212; the connecting ears 212 are hinged to the base 5.

[0039] Based on the above structure, by forming an open structure by mutually enclosing the supporting bottom frame 21, the first side plate 22, the second side plate 23, and the supporting back plate 24, a single-sided open structure for stacking cigarette boxes is formed, which facilitates material unloading by the mechanical gripper. At the same time, by setting the supporting sub-plate 211 near the connecting ear 212 at intervals with the connecting ear 212, interference between the supporting sub-plate 211 and the base 5 can be avoided during the rotation of the connecting ear 212. In addition, the supporting sub-plate 211 is set at intervals to form a grid structure, which can facilitate the later external forklift assembly to forklift the cigarette box material from the bottom as a whole, avoiding damage to the bottom cigarette box caused by inserting a flat bottom plate.

[0040] As an example, the support sub-plate 211 has a triangular structure as a whole. The support sub-plate 211 is vertically arranged on the support rear plate 213. The connection end between the support sub-plate 211 and the support rear plate 213 is the first end, and the end of the support sub-plate 211 away from the support rear plate 213 is the second end. From the first end to the second end, the size of the support sub-plate 211 is gradually reduced.

[0041] Based on the above structure, the support plate 211 is designed as a triangular structure so that the end of it away from the support plate 213 can expose as much space as possible, which is convenient for forklift transportation later.

[0042] As an example, the base 5 may include a base side plate 51, a base top plate 52, a base rear plate 53, and a base front plate 54; the base rear plate 53 and the base front plate 54 are arranged opposite each other along the width direction of the supporting base plate 11, and the base rear plate 53 and the base front plate 54 are arranged perpendicular to the supporting base plate 11; the base side plate 51 is arranged opposite each other along the length direction of the supporting base plate 11, and the base side plate 51 front plate is arranged perpendicular to the supporting base plate 11; the base top plate 52 is disposed on the base side plate 51, the base rear plate 53, and the base front plate 54, so that the whole forms a cavity structure;

[0043] Based on the above structure, the base side plate 51, base top plate 52, base rear plate 53 and base front plate 54 work together with the base plate 11 to form a cavity structure. As needed, a counterweight structure can be added to the cavity structure to ensure stability during transportation.

[0044] As an example, a support ear 55 is provided at the front end of the base side plate 51. The support ear 55 protrudes a predetermined distance away from the support base plate 11. The support ear 55 is provided with a hinge hole, and the temporary storage cavity is hinged through the support ear 55 and the connecting ear 212.

[0045] Based on the above structure, the support ear 55 is set to be protruding upwards in a predetermined manner, which can reserve space for the rotation of the temporary storage cavity, avoid interference between the temporary storage part 2 and the base top plate 52 when rotating, and make the entire rotation process smooth.

[0046] As an example, the support part 3 may include a support handrail 31, a first crossbar 32 and a second crossbar 33; the first crossbar 32 and the second crossbar 33 are respectively disposed between the two support handrails 31, so that the two support handrails 31 form a stable frame support structure; the first crossbar 32 is disposed between the two support handrails 31 near the end of the support back plate 24, and the second crossbar 33 is disposed between the support handrails 31 away from the support back plate 24; a third crossbar 34 is also disposed at the bottom position of the two support handrails 31.

[0047] Two first crossbars 32 are set parallel to each other between the two support handrails 31 to provide support space for the adjustment part 4.

[0048] Based on the above structure, the support part 3 is formed into a support structure that can be pushed and pulled by both hands by supporting the handrail 31, the first crossbar 32, the second crossbar 33 and the third crossbar 34, which makes it convenient for operators to push and pull stably. The parallel arrangement of the first crossbar 32 can provide a connection base for the adjustment part 4, which facilitates the subsequent adjustment operation.

[0049] As an example, the adjustment unit 4 may include a sliding block 41, a rotating handrail wheel 42, a lead screw 43, and a fixing plate 44; the fixing plate 44 is disposed between the two first crossbars 32, and the fixing plate 44 is provided with a threaded hole that mates with the lead screw 43; a guide rail 45 that mates with the sliding block 41 is provided on the support back plate 24; a connecting seat 46 and a rotating block 47 are provided on the sliding block 41, and the rotating block 47 is hinged to the connecting seat 46; a rotating bearing 48 is provided at the center of the rotating block 47; the ends of the lead screw 43 are respectively connected to the rotating bearing 48 and the rotating handrail wheel 42;

[0050] Based on the above structure, by rotating the handle wheel 42, the depth of the screw 43 screwing in and out of the fixed plate 44 can be adjusted, thereby realizing the adjustment of the pitch of the temporary storage section 2. At the same time, through the cooperation of the sliding block 41 and the guide rail 45, different positions can be selected for support according to the different centers of gravity of the storage cavity being carried, ensuring the stability of the support.

[0051] In this solution, the pitch angle of the temporary storage section 2 is adjusted by the adjustment unit 4 to facilitate the transportation of the temporary storage section 2. When the temporary storage section 2 needs to cooperate with the mechanical gripper for strip storage, the mechanical gripper is adjusted to a vertical position by the adjustment unit 4 to facilitate the cooperation with the vertically lifting mechanical gripper to complete the batch transfer operation of strips. When the temporary storage section 2 is fully loaded with strips, the temporary storage section 2 is adjusted to a pitch position by the adjustment unit 4 to prevent the temporary storage section 2 from falling out of the open temporary storage section 2 during transportation.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
