Description

Technical Field

[0001] The invention relates to the field of beverage packaging production equipment, and in particular to a bottle separation mechanism and a bottle separation method for beverage packaging. Background Art

[0002] In the beverage packaging production process, beverage bottles filled with beverages need to be packed into packaging boxes. The processes of the automatic packaging production line that completes this process are generally divided into bottle feeding, bottle separation, bottle rushing, and packaging bottles into packaging boxes; among them, bottle separation is a more important process. The efficiency of bottle separation, whether the bottle feeding structure is reasonably designed, and whether the bottle separation can be effectively carried out after bottle feeding are directly related to the progress of subsequent processes.

[0003] For existing beverage packaging machinery and equipment, the main problem with its bottle separation mechanism is that the bottle separation claw of the bottle separation mechanism does not provide continuous and linear support to the beverage bottle body in the horizontal direction. The horizontal bar drives the bottle separation claw to do reciprocating motion, and the motion trajectory of the horizontal bar is limited by the single fixed track embedded at both ends of the horizontal bar. The embedded single fixed track must ensure that the entire device rotates clockwise and counterclockwise smoothly, which causes the bottle separation claw to sometimes not provide continuous and linear support to the beverage bottle body in the horizontal direction, especially when the track changes, such as at the bend of the track, the bottle separation claw changes from the horizontal state to the vertical state, or the bottle separation claw changes from the vertical state to the horizontal state. Conversely, the beverage bottle body will also have a reaction force in the opposite direction to the bottle separation claw. When the bottle separation claw does not provide continuous and linear support to the beverage bottle body in the horizontal direction, the beverage bottle body is prone to tipping over and the bottles are not placed evenly after separation. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a bottle separation mechanism for beverage packaging, which can provide stable and strong support for the beverage bottle body during the entire stage of bottle separation, and the lateral support force for the beverage bottle body is continuous and linear, so that the task of bottle separation of the beverage bottle body can be completed better and faster.

[0005] Another object of the present invention is to provide a bottle dispensing method for beverage packaging.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A bottle separation mechanism for beverage packaging, comprising a left guard plate, a right guard plate, and one or more bottle separation components arranged between the left guard plate and the right guard plate; and also comprising motion tracks arranged on the left guard plate and the right guard plate;

[0008] The bottle separation assembly is used to separate the orderly flow of beverage bottles after the bottle feeding process in the horizontal direction;

[0009] Each of the motion tracks comprises a main cam motion track and an auxiliary cam motion track; both ends of each crossbar are fixedly connected to supporting feet, and the supporting feet are provided with main cam rollers and auxiliary cam rollers;

[0010] The main cam motion track is a completely closed annular or quasi-annular track; the auxiliary cam motion track is arranged inside a bent portion at one end of the main cam motion track and is an arc-shaped track with two open ends, and the straight lines where the two open ends are located are basically parallel to the horizontal section at the top of the main cam motion track;

[0011] When the support leg moves to the bending part where both the main cam motion track and the auxiliary cam motion track exist, the support leg is located in the sandwich layer between the plane where the main cam motion track and the plane where the auxiliary cam motion track are located, and the main cam roller and the auxiliary cam roller on the support leg are respectively placed in the main cam motion track and the auxiliary cam motion track;

[0012] When the movement reaches other positions where the main cam motion track exists but the auxiliary cam motion track does not exist, the main cam roller on the support foot is placed in the main cam motion track, and the auxiliary cam roller is suspended in the air.

[0013] Each of the bottle dividing components comprises a cross bar, one side of which is provided with one or more chain pins, and another opposite side of the cross bar is provided with a slot, in which one or more bottle dividing fingers are provided, and the bottle dividing fingers can move freely in the slot and can self-lock after being fixed in position; both ends of the cross bar are fixedly connected with a Y-shaped support leg comprising a first support leg and a second support leg, wherein the first support leg and the second support leg form an opening of the Y-shaped support leg, and the opening direction faces away from the slot; the main cam roller is installed on a side of the first support leg away from the cross bar, and the auxiliary cam roller is installed on a side of the second support leg close to the cross bar.

[0014] There are two auxiliary cam rollers, two auxiliary cam motion tracks, and two auxiliary cam rollers are respectively placed in the two auxiliary cam motion tracks, and the auxiliary cam motion track relatively close to the outside partially overlaps with the main cam motion track at the same position in the upper horizontal section, and the auxiliary cam motion track relatively close to the inside has a larger bending curvature in the middle section than the auxiliary cam motion track relatively close to the outside. The purpose of such a setting is to make the lateral support force of the bottle-splitting finger of the bottle-splitting mechanism on the beverage bottle body more continuous and linear through the limiting effect of the two auxiliary cam rollers and one main cam roller, especially the auxiliary cam motion track relatively close to the inside has a larger bending curvature in the middle section than the auxiliary cam motion track relatively close to the outside, which can further expand this advantage.

[0015] The relatively inner auxiliary cam motion track is opened at the bottom and tilted downward along the motion direction in the track. The purpose of such arrangement is to facilitate the auxiliary cam roller to enter the auxiliary cam motion track.

[0016] The chain pins are fixedly connected to the motor chain, and the cross bars of more than one bottle separation assembly are fixed to the motor chain through chain pins at different positions to form dislocation.

[0017] A tensioning mechanism is arranged on the inner side of the lower part of the closed loop formed by the motor chain, which can further ensure the tension of the motor chain, thereby further strengthening the support force of the bottle separation assembly on the beverage bottle body just entering the orderly bottle flow of the beverage bottle body.

[0018] There is one auxiliary cam roller and one auxiliary cam motion track. When there is only one auxiliary cam motion track, it cooperates with the main cam motion track to basically achieve the purpose: compared with before, the bottle separation mechanism can provide more stable and powerful support for the beverage bottle body during the entire stage of bottle separation.

[0019] The bottle separation mechanism for beverage packaging also includes parallel partition plates. The number of rows of beverage bottles formed by the partition plates is consistent with the number of rows of beverage bottles after the bottle feeding process is completed.

[0020] Another object of the present invention is achieved by the following technical solutions:

[0021] A bottle separation method for beverage packaging, comprising the following steps:

[0022] After the bottle feeding process, the beverage bottle enters the bottle separation process. The beverage bottle is placed on a conveyor belt with a gap. The conveyor belt carries the beverage bottle forward at a speed of V1. At the same time, the transmission mechanism (motor and motor chain) is fixedly connected to the bottle separation assembly (the motor chain is fixed to the chain pin of the cross bar), thereby driving the bottle separation assembly to move at a speed of V2. The movement direction is consistent with that of the beverage bottle. The parts of the bottle separation assembly that are in direct contact with the plastic bottle body (more than one bottle separation finger is provided in the cross bar slot) also move at a speed of V2.

[0023] When the support leg moves to the bending part where both the main cam motion track and the auxiliary cam motion track exist, the support leg is located in the sandwich layer between the plane where the main cam motion track and the plane where the auxiliary cam motion track are located, and the main cam roller and the auxiliary cam roller on the support leg are respectively placed in the main cam motion track and the auxiliary cam motion track;

[0024] The movement continues, and the parts of the bottle separation assembly that are in direct contact with the plastic bottle body (one or more bottle separation fingers are provided in the crossbar slot) extend to the plane where the conveyor belt is located through the gap of the conveyor belt, and V1 is greater than V2. Due to the speed difference, the beverage bottles on the conveyor belt are blocked by the parts of the bottle separation assembly that are in direct contact with the plastic bottle body (one or more bottle separation fingers are provided in the crossbar slot), thereby completing the orderly bottle flow separation of the beverage bottles;

[0025] Similarly, the conveyor belt on the same bottle separation station is staggered and fixedly connected to the bottle separation assembly through different transmission mechanisms (motor and motor chain) (the motor chain and the cross bar are fixed with chain pins at different positions), so as to achieve continuous bottle separation with smaller time intervals.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] The present invention provides an auxiliary cam motion track and a main cam motion track. An auxiliary cam roller is arranged in the auxiliary cam motion track at a bending portion at one end of the main cam motion track, and cooperates with a main cam roller arranged in the main cam motion track to jointly limit the motion track of the bottle dividing assembly, and at the same time strengthen the support force of the bottle dividing assembly on the beverage bottle body when the bottle dividing assembly just enters the orderly bottle flow of the beverage bottle body.

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0039] like Figures 1 to 8 , a bottle separation mechanism for beverage packaging, comprising a left guard plate, a right guard plate, and one or more bottle separation components arranged between the left guard plate and the right guard plate; and also comprising motion tracks arranged on the left guard plate and the right guard plate;

[0040] The bottle separation assembly is used to separate the orderly flow of beverage bottles after the bottle feeding process in the horizontal direction;

[0041] Each of the motion tracks comprises a main cam motion track and an auxiliary cam motion track; both ends of each crossbar are fixedly connected to supporting feet, and the supporting feet are provided with main cam rollers and auxiliary cam rollers;

[0042] The main cam motion track is a completely closed annular or quasi-annular track; the auxiliary cam motion track is arranged inside a bent portion at one end of the main cam motion track and is an arc-shaped track with two open ends, and the straight lines where the two open ends are located are basically parallel to the horizontal section at the top of the main cam motion track;

[0043] like Figure 2 Each of the bottle dividing components comprises a cross bar, one side of which is provided with one or more chain pins, and another opposite side of the cross bar is provided with a slot, in which one or more bottle dividing fingers are provided, and the bottle dividing fingers can move freely in the slot and can self-lock after being fixed in position; two ends of the cross bar are fixedly connected with a Y-shaped support leg comprising a first support leg and a second support leg, wherein the first support leg and the second support leg form an opening of the Y-shaped support leg, and the opening direction faces away from the slot; the main cam roller is installed on a side of the first support leg away from the cross bar, and the auxiliary cam roller is installed on a side of the second support leg close to the cross bar.

[0044] The shape of the bottle separating finger may vary according to the shape of the beverage bottle and the size and height of the bottle diameter.

[0045] At this time, after the bottle feeding process is completed, the beverage bottle body moves from left to right on the conveyor belt. The auxiliary cam motion track of the right guard plate is set on the inner side of the left end bend of the main cam motion track, and the auxiliary cam motion track is not set on the right end bend of the main cam motion track. The motor drives the cross bar to reciprocate clockwise through the motor chain. The setting method of the main cam motion track and the auxiliary cam motion track of the left guard plate is a mirror image of the setting method of the right guard plate. Similarly, if the beverage bottle body moves from right to left on the conveyor belt after the bottle feeding process is completed, the auxiliary cam motion track is set on the inner side of the right end bend of the main cam motion track, and it is not necessary to set the auxiliary cam motion track on the left end bend of the main cam motion track.

[0046] When the support leg moves to the bending part where both the main cam motion track and the auxiliary cam motion track exist, the support leg is located in the sandwich layer between the plane where the main cam motion track and the plane where the auxiliary cam motion track are located, and the main cam roller and the auxiliary cam roller on the support leg are respectively placed in the main cam motion track and the auxiliary cam motion track;

[0047] When the movement reaches other positions where the main cam motion track exists but the auxiliary cam motion track does not exist, the main cam roller on the support foot is placed in the main cam motion track, and the auxiliary cam roller is suspended in the air.

[0048] There are two auxiliary cam rollers, two auxiliary cam motion tracks, and two auxiliary cam rollers are respectively placed in the two auxiliary cam motion tracks, and the auxiliary cam motion track relatively close to the outside partially overlaps with the main cam motion track at the same position in the upper horizontal section, and the auxiliary cam motion track relatively close to the inside has a larger bending curvature in the middle section than the auxiliary cam motion track relatively close to the outside. The purpose of such a setting is to make the lateral support force of the bottle-splitting finger of the bottle-splitting mechanism on the beverage bottle body more continuous and linear through the limiting effect of the two auxiliary cam rollers and one main cam roller, especially the auxiliary cam motion track relatively close to the inside has a larger bending curvature in the middle section than the auxiliary cam motion track relatively close to the outside, which can further expand this advantage.

[0049] The relatively inner auxiliary cam motion track is opened at the bottom and tilted downward along the motion direction in the track. The purpose of such arrangement is to facilitate the auxiliary cam roller to enter the auxiliary cam motion track.

[0050] The chain pins are fixedly connected to the motor chain, and the cross bars of more than one bottle separation assembly are fixed to the motor chain through chain pins at different positions to form dislocation.

[0051] A tensioning mechanism is arranged on the inner side of the lower part of the closed loop formed by the motor chain, which can further ensure the tension of the motor chain, thereby further strengthening the support force of the bottle separation assembly on the beverage bottle body just entering the orderly bottle flow of the beverage bottle body.

[0052] The bottle separation mechanism for beverage packaging also includes parallel partition plates. The number of rows of beverage bottles formed by the partition plates is consistent with the number of rows of beverage bottles after the bottle feeding process is completed.

[0053] A bottle separation method for beverage packaging, comprising the following steps:

[0054] After the bottle feeding process, the beverage bottle enters the bottle separation process. The beverage bottle is placed on a conveyor belt with a gap. The conveyor belt carries the beverage bottle forward at a speed of V1. At the same time, the transmission mechanism (motor and motor chain) is fixedly connected to the bottle separation assembly (the motor chain is fixed to the chain pin of the cross bar), thereby driving the bottle separation assembly to move at a speed of V2. The movement direction is consistent with that of the beverage bottle. The parts of the bottle separation assembly that are in direct contact with the plastic bottle body (more than one bottle separation finger is provided in the cross bar slot) also move at a speed of V2.

[0055] When the support leg moves to the bending part where both the main cam motion track and the auxiliary cam motion track exist, the support leg is located in the sandwich layer between the plane where the main cam motion track and the plane where the auxiliary cam motion track are located, and the main cam roller and the auxiliary cam roller on the support leg are respectively placed in the main cam motion track and the auxiliary cam motion track;

[0056] The movement continues, and the parts of the bottle separation assembly that are in direct contact with the plastic bottle body (one or more bottle separation fingers are provided in the crossbar slot) extend to the plane where the conveyor belt is located through the gap of the conveyor belt, and V1 is greater than V2. Due to the speed difference, the beverage bottles on the conveyor belt are blocked by the parts of the bottle separation assembly that are in direct contact with the plastic bottle body (one or more bottle separation fingers are provided in the crossbar slot), thereby completing the orderly bottle flow separation of the beverage bottles;

[0057] Specifically:

[0058] like Figure 3 At this time, the main cam roller is in the main cam motion track, and the first secondary cam roller and the second secondary cam roller are about to enter the first secondary cam motion track and the second secondary cam motion track.

[0059] like Figure 4 At this time, the main cam roller is still in the main cam motion track, the first auxiliary cam roller and the second auxiliary cam roller have just entered the first auxiliary cam motion track and the second auxiliary cam motion track respectively, and the second leg of the Y-shaped leg is in the sandwich layer between the plane where the main cam motion track is located and the plane where the auxiliary cam motion track is located.

[0060] like Figure 5At this time, the main cam roller, the first auxiliary cam roller and the second auxiliary cam roller continue to move on the main cam motion track, the first auxiliary cam motion track and the second auxiliary cam motion track respectively, the second leg of the Y-shaped leg is still in the sandwich layer between the plane where the main cam motion track is located and the plane where the auxiliary cam motion track is located, and the bottle separating finger begins to extend above the plane where the conveyor belt is located.

[0061] like Figure 6 At this time, the main cam roller continues to move on the main cam motion track, and the main cam roller is in the interlayer between the plane where the main cam motion track is located and the plane where the auxiliary cam motion track is located, that is, the first leg of the Y-shaped leg is in the interlayer between the plane where the main cam motion track is located and the plane where the auxiliary cam motion track is located, the first auxiliary cam roller and the second auxiliary cam roller have left the first auxiliary cam motion track and the second auxiliary cam motion track, and the bottle dividing finger has been completely extended above the plane where the conveyor belt is located.

[0062] like Figure 7 At this time, the bottle separating finger blocks the beverage bottle body and continues to move forward, and the main cam roller continues to move on the main cam motion track; the first auxiliary cam roller and the second auxiliary cam roller have left the first auxiliary cam motion track and the second auxiliary cam motion track and are in a suspended state.

[0063] like Figure 8 At this time, a beverage bottle separating action is completed, and the bottle separating finger rotates clockwise downward at the bent portion at the other end where the auxiliary cam motion track is not set, and the main cam roller continues to move on the main cam motion track; the first auxiliary cam roller and the second auxiliary cam roller have left the first auxiliary cam motion track and the second auxiliary cam motion track and are in a suspended state.

[0064] Similarly, the conveyor belt on the same bottle separation station is staggered and fixedly connected to the bottle separation assembly through different transmission mechanisms (motor and motor chain) (the motor chain and the cross bar are fixed with chain pins at different positions), so as to achieve continuous bottle separation with smaller time intervals.

[0065] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
