Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging machines, in particular to a cigarette packet replenisher. Background Art

[0002] The replenisher device of the ZB55 transparent forming machine is an important part of the equipment and is used to supplement the cigarette packets missing due to equipment rejection at the conveying station during the production process. There are two replenishing methods: ordinary type: the upper end of the lowermost cigarette packet to be replenished in the replenishing warehouse is restricted in the replenishing warehouse, and the lower end always abuts against the cigarette packet in the conveying wheel or the die box. When an empty die box to be replenished appears, the lowermost cigarette packet to be replenished will directly fall into the die box to be replenished; clamping type: the lowermost cigarette packet to be replenished is clamped and fixed in the replenishing warehouse. When the photoelectric detector detects an empty die box to be replenished, the clamping is controlled to be released, and the lowermost cigarette packet to be replenished can fall into the die box to be replenished.

[0003] In order to facilitate the smooth falling of the cigarette packets in the replenishing warehouse, the gap between the front and rear of the cigarette packets in the replenishing warehouse is relatively large during normal production. When the cigarette packets fall into the die box to be replenished, the cigarette packets are likely to collide with the inner wall of the die box to be replenished, resulting in blockage, and phenomena such as jamming and misalignment are likely to occur during operation. Troubleshooting such faults is very troublesome. Once the above situation occurs, troubleshooting takes a long time, seriously affecting the efficiency of the equipment.

[0004] The patent document with the publication number CN216581213U discloses a side replenishing device for a packaging machine, including a side cigarette warehouse, a pushing component and a driving device; the side cigarette warehouse is arranged on the outer edge of the replenishing station of the output wheel of the packaging machine, a cigarette packet platform is arranged at the bottom of the side cigarette warehouse, a cigarette packet to be replenished is arranged on the cigarette packet platform, and the upper surface of the cigarette packet platform is flush with the upper surface of the die box in the replenishing station; the cigarette packet platform is clamped between the output wheel and the pushing component, and the driving device drives the pushing component, and the pushing component makes a reciprocating motion along the radial direction of the output wheel.

[0005] The prior art replenishes cigarettes by pushing the cigarette packets into the die box from the side. Although it can solve the adverse factors such as the position deviation and friction between the cigarette packets to be replenished and the output wheel during the falling process, it is necessary to adjust the installation position of the cigarette warehouse, add structures such as a pushing component and a driving device, and there are problems of inconvenient transformation and high transformation cost. Utility Model Content

[0006] The utility model aims to solve the above problems and provides a cigarette packet replenisher with convenient transformation and low transformation cost.

[0007] The technical solution for the present utility model to solve the problem is to provide a cigarette pack replenisher, which includes a replenishing bin for accommodating the cigarette packs to be replenished. An outlet is provided at the bottom of the replenishing bin through which the cigarette packs to be replenished can pass and fall into the mold box to be replenished. The replenishing bin includes a pair of opposite forming plates, and there is a gap between the cigarette pack to be replenished and at least one of the forming plates. At least one of the forming plates includes a solid part and a through-hole part. The cigarette pack replenisher further includes a control member, which includes a fixed seat and a guide plate hinged to the fixed seat. The guide plate includes a working part located in the replenishing bin after passing through the through-hole part. When no replenishment is needed, the cigarette pack to be replenished abuts against the upper surface of the working part. When replenishment is needed, the guide plate rotates around the fixed seat so that a limiting through-port is formed between the end of the working part and the forming plate opposite thereto.

[0008] As a preference of the present utility model, the distance between the horizontal plane where the limiting through-port is located and the horizontal plane where the top surface of the mold box to be replenished is located is less than the height of the cigarette pack to be replenished.

[0009] As a preference of the present utility model, it further includes a positioning part. When replenishment is needed, the guide plate rotates around the fixed seat until it abuts against the positioning part.

[0010] As a preference of the present utility model, it further includes an adjusting part for adjusting the position of the positioning part in the direction of the two forming plates.

[0011] As a preference of the present utility model, it further includes a fixing plate, which includes a mounting part mounted on the solid part and a suspended part located in the through-hole part. A screw is threadedly connected to the suspended part, and the end of the screw forms the positioning part.

[0012] As a preference of the present utility model, it further includes a locking member, which includes a spring bolt provided on the fixed seat and a pin hole provided on the guide plate. When no replenishment is needed, the spring bolt is inserted into the pin hole.

[0013] As a preference of the present utility model, the fixed seat is mounted on the solid part.

[0014] As a preference of the present utility model, the end of the working part is arc-shaped.

[0015] As a preference of the present utility model, a lubricating layer is provided at the end of the working part.

[0016] As a preference of the present utility model, a sensor for detecting the mold box to be replenished is provided at the bottom of the replenishing bin.

[0017] The beneficial effects of the present utility model:

[0018] 1. In this application, a control component is added to the cigarette replenishment bin. When cigarette replenishment is not required, it can support the cigarette packs to be replenished, and compared with the ordinary cigarette replenishment device in the prior art, it can prevent the cigarette packs to be replenished from contacting the conveying wheel and being damaged by friction; compared with the clamping type cigarette replenishment device in the prior art, it can cancel the clamping structure to reduce costs and avoid the clamping damage to the cigarette packs to be replenished by the clamping structure. When cigarette replenishment is required, the rotation angle of the guide plate can be adjusted to adjust the size of the limiting through-hole, and the position of the cigarette outlet of the cigarette pack to be replenished is restricted through the limiting through-hole, avoiding the position deviation of the cigarette pack to be replenished in the horizontal direction and ensuring that the cigarette pack to be replenished accurately falls into the cigarette mold box to be replenished.

[0019] 2. This application only needs to set a through-hole part and install a control component on the existing cigarette replenishment bin, which has the advantages of simple transformation, few required parts and low cost. Brief Description of the Drawings

Detailed Description of the Embodiment

[0026] The following are the detailed embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the drawings, but the present invention is not limited to these embodiments.

[0027] A cigarette pack replenishment device, as Figures 1-3 shown, includes a cigarette replenishment bin 2 erected above the conveying wheel. A number of cigarette packs 1 to be replenished are stacked vertically in the cigarette replenishment bin 2. The bottom of the cigarette replenishment bin 2 is provided with an outlet through which the cigarette packs 1 to be replenished can pass so that the cigarette packs 1 to be replenished fall into the cigarette mold box 3 to be replenished on the conveying wheel. Matching the shape of the cigarette packs 1 to be replenished, the cigarette replenishment bin 2 is square and is composed of four forming plates 21.

[0028] Generally speaking, the size of the inner cavity of the cigarette replenishment bin 2 does not exactly match the size of the cigarette pack 1 to be replenished. If it does, the cigarette pack 1 to be replenished will be stuck in the cigarette replenishment bin 2 due to friction and unable to fall for replenishment. Therefore, there is a gap between the cigarette pack 1 to be replenished and at least two non-opposite inner walls of the cigarette replenishment bin 2. The existing cigarette replenishment methods are as follows: Ordinary type: The upper end of the lowermost cigarette pack 1 to be replenished in the cigarette replenishment bin 2 is restricted inside the cigarette replenishment bin 2, and the lower end always abuts against the cigarette pack on the conveying wheel or in the die box. Clamping type: The lowermost cigarette pack 1 to be replenished is clamped and fixed inside the cigarette replenishment bin 2. When an empty die box 3 to be replenished appears, the lowermost cigarette pack 1 will directly or, after releasing the clamp, naturally fall into the die box 3 to be replenished. However, due to the existence of the gap between the cigarette pack 1 to be replenished and the inner wall of the cigarette replenishment bin 2, the falling position of the cigarette pack 1 to be replenished will deviate, causing the cigarette pack 1 to be replenished to be hooked on the edge of the die box 3 to be replenished and unable to fall in place, resulting in problems such as blockage and jamming when the output wheel continues to rotate.

[0029] Therefore, in this application, a limiting through-port 22 with a size consistent with that of the cigarette pack 1 to be replenished but a very short stroke, which will not cause the cigarette pack 1 to be replenished to be stuck, is formed at the outlet of the cigarette replenishment bin 2, so that the falling position of the cigarette pack 1 to be replenished corresponds to the position of the die box 3 to be replenished, ensuring that the cigarette pack 1 to be replenished accurately falls into the die box 3 to be replenished.

[0030] Specifically: First, adjust the structure of the cigarette replenishment bin 2 to prepare for subsequent installation. As Figure 4 shown, a forming plate 21 includes a solid part 211 and a through-hole part 212. This forming plate 21 is preferably one of the two forming plates 21 arranged in sequence along the tangential direction of the conveying wheel. This is because generally, the die box 3 to be replenished is closed on three sides and open on one side, that is, the side away from the center of the conveying wheel along the radial direction. The distance between the two sides along the tangential direction of the conveying wheel is fixed, and it is easier to have the problem of not falling in place. Therefore, it is necessary to adjust the size of the outlet of the cigarette replenishment bin 2 along the tangential direction of the conveying wheel to correspond to it. The structure of other forming plates 21 is not restricted. For example, according to the design method of this embodiment, the forming plate 21 on the right includes two solid parts 211, which are respectively connected to the front and rear forming plates 21, and a through-hole part 212 is naturally formed between the two solid parts 211; other forming plates 21 are closed. It should be noted that, in essence, the existing cigarette replenishment bin 2 already has this structure, and the through-hole part 212 is for facilitating a person's hand or a machine to reach into the cigarette replenishment bin to clamp the cigarette pack. The modification to the cigarette replenishment bin 2 itself in this application is relatively small.

[0031] Secondly, a control member is added. As Figures 1-3 shown, the control member includes a fixed seat 41 and a guide plate 42 hinged to the fixed seat 41. The installation position of the fixed seat 41 is not restricted, and it can be fixedly installed near the cigarette replenishment bin 2. In some embodiments, as Figure 4As shown, it is preferable to install both ends of the fixed seat 41 to the two solid parts 211 by screws respectively, reducing its floor area. The way of hinging the guide plate 42 and the fixed seat 41 is not limited. In some embodiments, the part of the fixed seat 41 located in the through-hole part 212 is provided with a notch, a pin shaft is arranged in the notch, and a movable seat is rotatably sleeved on the pin shaft. Just connect the movable seat with the guide plate 42. The length direction of the guide plate 42 is perpendicular to the axial direction of the pin shaft. In addition, grooves should be provided on the top surface and side surface of the fixed seat 41 to ensure that the guide plate 42 can rotate to the horizontal position and the vertical position. Then control one end of the guide plate 42 to pass through the through-hole part 212 and be located in the supplementary cigarette bin 2 to form a working part 421, and the other end is located outside the supplementary cigarette bin 2 to form a control part.

[0032] As Figure 1 shown, when the guide plate 42 is in the horizontal state, the cigarette packet to be supplemented 1 abuts against the upper surface of the working part 421. At this time, it is the state without cigarette supplement. The working part 421 can support the cigarette packet to be supplemented 1. Compared with the ordinary cigarette supplementer, it can avoid abutting against the conveying wheel and being damaged by friction; compared with the clamping type cigarette supplementer, the clamping structure can be cancelled and the clamping damage to the cigarette packet to be supplemented 1 by the clamping structure can be avoided.

[0033] As Figure 2 shown, when the guide plate 42 rotates counterclockwise, the working part 421 no longer supports the cigarette packet to be supplemented 1, and a limiting through-port 22 is formed between the upper left corner of its end and the left forming plate 21. By controlling the rotation angle of the guide plate 42, the position of the end of the working part 421 can be controlled, and thus the size of the limiting through-port 22 in the left-right direction can be controlled to be applicable to cigarette packets to be supplemented 1 of different sizes. Among them, the changes of the cigarette packet to be supplemented 1 in this process can refer to Figure 1 , Figure 3 , Figure 2 of this application in sequence. Specifically: when the working part 421 rotates from the Figure 1 horizontal state to the Figure 3 inclined state expressed by the solid line, the cigarette packet to be supplemented 1 first falls vertically, and then its lower right end abuts against the solid line working part 421. At this time, other parts of the cigarette packet to be supplemented 1 are not supported and are unbalanced. Therefore, it tilts and its upper left end abuts against the forming plate 21, forming the Figure 3 cigarette packet to be supplemented 1 in the solid line state. Then the working part 421 continues to rotate counterclockwise to the state expressed by the dotted line. Then, based on its own weight center, the cigarette packet to be supplemented 1 will return to the vertical state, such as the Figure 3 state expressed by the dotted line. Thus, the cigarette packet to be supplemented 1 originally located at the center of the supplementary cigarette bin 2 in Figure 1 is transformed into the state where its left side abuts against the forming plate 21 in Figure 3 . Subsequently, it continues to fall in this state, that is, the state in Figure 2 is formed.The cigarette pack 1 to be replenished, when the cigarette pack 1 to be replenished is in the limiting through opening 22, its opposite two sides are respectively in contact with the forming plate 21 and the working part 421, so that the cigarette pack 1 to be replenished will not shift. After the cigarette pack 1 to be replenished passes through the limiting through opening 22, it can replenish cigarettes into the cigarette mold box 3 to be replenished.

[0034] In some embodiments, the distance between the horizontal plane where the limiting through opening 22 is located and the horizontal plane where the top surface of the cigarette mold box 3 to be replenished is located should not be too large, otherwise the cigarette pack 1 to be replenished may shift during the natural falling process. Preferably, the distance is controlled such that when the upper end of the cigarette pack 1 to be replenished is still in the limiting through opening 22, the lower end has already entered the cigarette mold box 3 to be replenished; that is, the distance between the horizontal plane where the limiting through opening 22 is located and the horizontal plane where the top surface of the cigarette mold box 3 to be replenished is less than the height of the cigarette pack 1 to be replenished. This adjustment can be achieved by lengthening the length of the working part 421 or reducing the installation height of the fixed seat 41, so that the end of the working part 421 can pass through the outlet of the cigarette replenishment bin 2 and be located outside the cigarette replenishment bin 2, thereby realizing this adjustment; thus, without adjusting the installation position of the cigarette replenishment bin 2, the distance between the horizontal plane where the limiting through opening 22 is located and the horizontal plane where the top surface of the cigarette mold box 3 to be replenished can be reduced.

[0035] Since in the limiting through opening 22, the cigarette pack 1 to be replenished is in contact with the end of the working part 421, especially the included angle between the upper surface and the side surface, in some embodiments, the end of the working part 421 is arc-shaped. In some embodiments, the end of the working part 421 is provided with a lubricating layer, preferably a flexible material with a low coefficient of friction, such as a polytetrafluoroethylene layer.

[0036] In some embodiments, in order to determine and maintain the rotation angle of the guide plate 42 during cigarette replenishment, a positioning part 5 is further included. When cigarette replenishment is required, the guide plate 42 rotates around the fixed seat 41 until it abuts against the positioning part 5. In order to adapt to different rotation angles of the guide plate 42, the position of the positioning part 5 in the direction where the two forming plates 21 are located, that is, Figure 1 the left-right direction in Figure 4 should be adjustable. Its adjustment method is not limited. Preferably, in this embodiment: a fixing plate is further included. As Figure 1 shown, the fixing plate includes an installation part installed on the solid part 211 and a suspended part located in the through hole part 212. A screw is threadedly connected to the suspended part. The axial direction of the screw is the direction where the two forming plates 21 are located, that is,

[0037] the left-right direction in Figure 5As shown in the figure, the locking member includes a spring bolt 61 provided on the fixed seat 41 and a pin hole 62 provided on the guide plate 42. When no supplementary smoking is required, the guide plate 42 is in a horizontal state. At this time, the positions of the spring bolt 61 and the pin hole 62 correspond to each other, and the spring bolt 61 is inserted into the pin hole 62, so that the guide plate 42 cannot rotate, thus being able to support the cigarette pack 1 to be supplemented with smoke. When supplementary smoking is required, the spring bolt 61 is pulled out of the pin hole 62 manually or mechanically. After the guide plate 42 rotates, the pin hole 62 on the guide plate 42 no longer corresponds to the position of the spring bolt 61. Among them, the mechanical control method of the spring bolt 61 can be a cylinder, and the piston rod of the cylinder can be connected to the spring bolt 61.

[0038] During supplementary smoking, the inner cavity of the cigarette supplementing die box 3 should correspond to the limiting through port 22. As a preference of the present invention, a sensor for detecting the cigarette supplementing die box 3 is further provided at the bottom of the cigarette supplementing warehouse 2. The sensor is electrically connected to a buzzer or the cylinder for driving the spring bolt 61. When the cigarette supplementing die box 3 is detected, the buzzer emits a sound to remind the operator to control the rotation of the guide plate 42, or sends a signal to the cylinder to control the spring bolt 61 to be pulled out of the pin hole 62, and the guide plate 42 rotates naturally under the action of gravity.

[0039] Among them, the sensor is not limited, and a commonly used sensor in the prior art can be adopted. For example, it can be two sets of photoelectric sensors, and the first photoelectric sensor is electrically connected to the second photoelectric sensor. The first photoelectric sensor is electrically connected to a buzzer or a cylinder. The first photoelectric sensor includes a first light emitter, a first light receiver, and a first photoelectric switch; the second photoelectric sensor includes a second light emitter, a second light receiver, and a second photoelectric switch. At the bottom of the left forming plate 21 of the cigarette supplementing warehouse 2 opposite to the forming plate 21 where the control member is located, that is Figure 1 the bottom of the left forming plate 21, a first light emitter is provided, and a second light emitter is provided to emit light sources. A first light receiver is provided on the left top surface of each die box, and a second light receiver is provided in the inner cavity of each die box. When no supplementary smoking is required, the second light receiver is blocked by the cigarette pack in the die box and cannot receive light, so that the second photoelectric switch outputs a closed signal to the first light emitter, making the first photoelectric sensor in a closed state. When the second light receiver can receive light, it indicates that there is a cigarette supplementing die box 3. The second photoelectric switch outputs an open signal to the first light emitter, and the first light emitter emits a light source. When the first light receiver receives the light, it outputs an open signal to the buzzer or the cylinder.
