Description

Technical Field

[0001] The invention relates to a cigarette carton packaging and sorting technology, and in particular to a cigarette carton stacking mechanism. Background Art

[0002] In the logistics sorting and packaging process of the commercial tobacco industry, the cigarettes coming out of the end of the sorting line enter the heat shrink film packaging machine. First, the cigarette cartons need to be stacked into piles according to customer orders. The traditional stacking method is inefficient and not very stable.

[0003] Specifically, the transmission stacking mechanism is to set limit plates above both sides of the conveyor line, and to set penetrable cigarette supporting plates on both sides of the limit plates, and to set top plates below both sides of the conveyor line. The top plates are driven up and down by the lifting mechanism to realize the lifting of the cigarette strips. In the lifting process, either the cigarette strips are squeezed by the cigarette supporting plates to make the cigarette supporting plates avoid the lifting and stacking, or an additional cigarette supporting plate telescopic mechanism is added to drive the cigarette supporting plates to move horizontally to avoid the lifting. In the former, the cigarette strips may cause damage to both ends of the cigarette strips during the process of squeezing the cigarette supporting plates to avoid the lifting, and the cigarette jam may easily occur. In the latter, an additional mechanism is used to drive the cigarette supporting plates to move horizontally, which requires a high degree of linkage between the mechanism and the lifting mechanism, that is, a high requirement for the accuracy of the linkage control. Invisibly, the production difficulty and production cost of the mechanism are increased, and the failure rate is also high.

[0004] Therefore, it is urgent to involve a new cigarette stacking device to solve the above-mentioned problems. Summary of the invention

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example: Figures 1 to 3 As shown, the cigarette stacking mechanism of this embodiment includes a limit plate 1, two of which are provided, and are vertically arranged and parallel to each other, and a mounting carrier 11 is respectively provided on one side of the lower part of the two limit plates 1 away from each other; a cigarette supporting plate 2, two of which are provided, and horizontally pass through the through holes adapted at the same height of the lower part of the two limit plates 1, and the two cigarette supporting plates 2 are respectively connected to the mounting carrier 11 on the corresponding side through elastic telescopic parts 3; a conveyor line 4, the discharging end of the conveyor line 4 horizontally extends to the lower part between the two limit plates 1, and is located below the through holes; a top plate 5, two of which are provided and are located between the two limit plates 1, and the two are vertically and parallel to each other and arranged on the conveyor Both sides of the conveying line 4; a lifting mechanism 6, which is transmission-connected to the two top plates 5, and is used to drive the two top plates 5 to move downward to below the conveying surface of the conveying line 4, or to move upward to above the perforations; an extrusion assembly 7, which is connected to the two elastic telescopic members 3, and the two extrusion assemblies 7 are used to synchronously extrude the two elastic telescopic members 3 during the rising process of the top plates 5, thereby driving the two cigarette supporting plates 2 to move and contract from the corresponding perforations to the outsides of the two limit plates 1, or to gradually extend the two elastic telescopic members 3 during the descending process of the top plates 5, thereby driving the two cigarette supporting plates 2 to pass through the corresponding perforations and extend between the two limit plates 1.

[0023] In this embodiment, the operation process is as follows:

[0024] The cigarette strips are transported to the discharge end (i.e., the lifting station between the two limit plates 1) via the conveyor line 4. The cigarette strips cross the conveying surface of the conveyor line 4 horizontally, and the two ends are placed above the two sides of the conveyor line 4. Next, the lifting mechanism 6 drives the two top plates 5 to move upward and contact the cigarette strips (attached Figure 1 When the cigarette is lifted up, the extrusion assembly 7 simultaneously squeezes the two elastic telescopic parts 3, so that the two cigarette supporting plates 2 move outward and exit the perforations of the limit plate 1, so that the cigarette supporting plates 2 avoid the cigarette, and the cigarette passes through the perforations smoothly until the maximum stroke (in this state, the ground height of the cigarette is higher than the upper end height of the cigarette supporting plates 2). After that, the lifting mechanism 6 drives the top plate 5 to move downward. At the same time, the extrusion assembly 7 releases the elastic telescopic parts 3 (that is, the extrusion state is released). The elastic telescopic parts 3 drive the cigarette supporting plates 2 to move horizontally through the perforations and extend into the limit plates 1 on both sides (that is, extend into the corresponding ends of the cigarette). In the process of continuing to descend, the cigarette falls on the two cigarette supporting plates 2, and the top plate 5 continues to move down to the maximum stroke. Repeat the above actions, and the cigarette will be stacked up and down on the two cigarette supporting plates 2. The structural design of the entire mechanism is reasonable, which can realize the automatic avoidance of the cigarette supporting plates during the lifting of the cigarette, and the linkage between the structures is good, which reduces the control accuracy of the mechanism operation and reduces the production cost.

[0025] It should be noted that the parts involved in the cigarette stacking mechanism of this embodiment are all installed on a matching frame.

[0026] Preferably, the mounting carrier 11 is a mounting plate that is vertically arranged and parallel to the limiting plate 1 , so as to facilitate the installation of the elastic telescopic member 3 and facilitate the telescopic and translational movement of the cigarette supporting plate 2 .

[0027] As a preferred embodiment, the elastic telescopic member 3 includes a guide rod 31 and an elastic member 32. The guide rod 31 is perpendicular to the limiting plate 1 and passes through a matching guide hole on the mounting carrier 11 on the corresponding side. The cigarette supporting plate 2 is horizontally mounted on one end of the guide rod 31 close to the limiting plate 1. The elastic member 32 is connected between one end of the guide rod 31 close to the limiting plate 1 and the corresponding mounting carrier 11.

[0028] In this embodiment, the elastic telescopic member 3 has a reasonable structural design and can well realize the telescopic and translational movement of the cigarette supporting plate 2 .

[0029] As a preferred embodiment, a baffle 33 is provided at one end of the guide rod 31 close to the limit plate 1, the cigarette supporting plate 2 is installed on the side of the baffle 33 away from the guide rod 31, and the elastic member 32 is a spring, which is sleeved outside the guide rod 31 and connected between the baffle 33 and the mounting carrier 11 on the corresponding side.

[0030] In this embodiment, the design of the baffle 3 is conducive to the stable assembly of the spring on the guide rod 31 .

[0031] As a preferred embodiment, the extrusion assembly 7 includes a rocker 71 and a limit rod 72. A rocker mounting seat 73 is provided on the outer side of the top plate 5. The rocker 71 is vertically arranged, and its lower end is rotatably mounted on the rocker mounting seat 73 through a torsion spring. A rolling member 74 is provided on its upper end. The limit rod 72 is vertically mounted on the outer side of the top plate 5 on the corresponding side and is placed above the rocker mounting seat 73. A guide block 34 is provided at either end of the baffle 33. The upper end of the guide block 34 is vertical, and its lower end faces the limit block 73 on the corresponding side. The lower outer side of the positioning plate 1 is inclined and extends; in the initial state, the above-mentioned swing rod 71 is in a vertical state under the action of the torsion spring, and is against the above-mentioned limiting rod 72, and the above-mentioned rolling member 74 is located below the inclined section of the above-mentioned guide block 34. When the above-mentioned lifting mechanism 6 drives the two above-mentioned limiting plates 1 to move upward synchronously and lift the cigarettes delivered to the above-mentioned conveyor line 4, the above-mentioned rolling member 74 moves to contact the inner side of the above-mentioned guide block 34, and rolls along the inner side of the above-mentioned guide block 34, and squeezes the above-mentioned guide block 34 outward, so that the above-mentioned guide block 3 4 and the baffle plate 33 move outwards, and drive the cigarette supporting plate 2 to move outwards and exit the corresponding perforations, so that the cigarette supporting plate 2 avoids the two ends of the cigarette stick raised below, and when the top plate 5 moves upwards to the maximum stroke, the rolling member 74 moves to the top of the vertical section of the guide block 34, the squeezing force disappears, and the elastic telescopic member 3 drives the cigarette supporting plate 2 to move inwards through the perforations and is supported below the end of the raised cigarette stick; when the lifting mechanism 6 drives the top plate 5 to move downwards from the highest point, the cigarette stick moves downwards And supported on the above-mentioned cigarette supporting plate 2, the above-mentioned rolling member 74 moves downward, and rolls downward along the outer side of the above-mentioned guide block 34, and squeezes the above-mentioned guide block 34 inwardly and stretches the above-mentioned elastic telescopic member 3, and when the above-mentioned top plate 5 moves downward to the maximum stroke, the above-mentioned rolling member 74 moves to the outer side and below the inclined section of the above-mentioned guide block 34, and the inclined section of the above-mentioned guide block 34 returns to its original position under the elastic recovery of the above-mentioned elastic telescopic member 3, and at the same time, the above-mentioned rocker arm 71 returns to a vertical state under the action of the torsion spring, so that the above-mentioned rolling member 74 is located below its inclined section.

[0032] In this embodiment, the extrusion assembly 7 is linked with the lifting mechanism 6 to realize the real-time automatic avoidance of the cigarette supporting plate 2 during the rising and stacking process of the cigarette strips. The design is very clever. Specifically, when the lifting mechanism 6 drives the top plate 5 to rise, the top plate 5 drives the swing rod 71 to move upward and contact the inner side of the inclined section of the guide block 34, and rolls upward along the guide block 34. When the inclined section is completed during the rolling process, the cigarette supporting plate 2 just exits the corresponding perforation, and the upper end of the cigarette strip just moves close to the lower edge of the perforation. After that, the rolling member 74 rolls upward along the inner side of the vertical section of the guide block 34, and the cigarette strip passes through The cam 74 is in a state of being lifted up and out of the way, and the ... The cigarette falls on the upper end of the cigarette supporting plate 2, and the rolling element 74 contacts the outer side surface of the inclined section of the guide block 34 and rolls along the outer side surface (in this state, the swing rod 71 is tilted outward at a certain angle by the reaction force of the inclined section of the guide block 34, the torsion spring is deformed by force, and the guide block 34 stretches the elastic telescopic element 5 inward), until the top plate 5 moves downward to the maximum stroke, and the rolling element 74 completely detaches from the inclined section of the guide block 34 at the same time. At this time, the rolling element 74 and the swing rod 71 are not constrained by external force, and return to their original position (swing to vertical) under the action of the torsion spring, and the elastic telescopic element 5 contracts to make the guide block 34 Block 74 translates outward, and rolling element 74 moves relatively to below the inclined section of guide block 34), that is, returns to the initial position, and then the next cigarette strips can be pushed and stacked according to the above-mentioned operation process until they are stacked to a suitable stacking size, and the cigarette strips are removed. In this embodiment, the entire extrusion assembly 7 is linked with the lifting mechanism 6, and the entire control of the mechanism is only the operation of the lifting mechanism 6, which greatly reduces the control difficulty. In addition, the linkage nature makes the operation error of the equipment small and the precision requirement is also low, which reduces the production cost and operation difficulty of the mechanism.

[0033] The above-mentioned rocker arm mounting seat 73 is a rod-shaped seat body perpendicular to the top plate 5 , and one end of the corresponding rocker arm 71 is assembled on an end of the rocker arm mounting seat 73 away from the top plate 5 .

[0034] Preferably, the rolling element 74 is a deep groove ball bearing with its axis arranged horizontally, which facilitates good rolling contact between the rolling element 74 and the inner and outer sides of the guide block 34 .

[0035] As a preferred embodiment, the jacking mechanism 6 includes two vertical rails 61, a connecting rod 62 and a crankshaft transmission mechanism 63. The two vertical rails 61 are arranged below the two limit plates 1 and are respectively placed on the outer sides of the two top plates 5 in a one-to-one manner. The two top plates 5 are respectively slidably installed on the corresponding vertical rails 61 through sliders 64. The connecting rod 62 is horizontally and vertically connected between the two top plates 5. The crankshaft transmission mechanism 63 is transmission-connected to the connecting rod 62 to drive the connecting rod 62 to drive the two top plates 5 to move up and down.

[0036] In this embodiment, the lifting mechanism 6 utilizes the crankshaft transmission mechanism 63 to realize the reciprocating up and down movement of the connecting rod 62 and the top plate 5. The operation process is relatively stable, and the structural design is simple and convenient.

[0037] The above-mentioned crankshaft transmission mechanism 63 is a prior art, which specifically includes a motor and a crank-connecting rod pair. The motor is connected to the crank in the crank-connecting rod pair. The crank-connecting rod assembly in the crank-connecting rod pair is sleeved on the connecting rod 62. The motor drives the crank to rotate, so that the crank-connecting rod assembly can drive the connecting rod 62 and the top plate 5 to move up and down along the vertical rail 61.

[0038] It should be noted that the two top plates 5 can be replaced by other push members, and should not be limited to the design of two split plates in this embodiment.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
