Description

Technical Field

[0001] The utility model relates to the field of cartoning machines, in particular to a compression cartoning machine. Background Art

[0002] When the existing cartoning machine packs hard packaging such as plastic medicine bottles and glass bottles, the rigid push rod can directly push the packaging into the box. Figure 1 The schematic diagram of the existing cartoning machine for packing packages is presented. Figure 1 , the prior art cartoning machines include:

[0003] The carrier 1 has a guide groove 13 formed on its top, the guide groove 13 is used to place the package 22 and can guide the package 22 to move toward the packaging box 21, and the width of the guide groove 13 is smaller than the inner width of the packaging box 21;

[0004] The push handle 2 is arranged on the opposite side of the packaging box 21 relative to the carrier 1, and is used to push the packaging 22 to move along the guide groove 13 to the inside of the packaging box 21. The push handle 2 is usually driven by a cylinder or a servo push rod.

[0005] Soft packaging materials 22 such as strip packaging, three-side sealed and four-side sealed pouches are relatively soft and usually need to be compressed before being pushed into the packaging box 21. However, the push rod size at the pushing position of the existing cartoning machine is fixed and cannot meet the requirement of compressing the size of the packaged material 22 when being pushed into the paper box.

[0006] Combination Figure 1 The width of the package 22 is greater than the inner width of the packaging box 21 and the width of the guide groove 13, and the width of the guide groove 13 is less than the inner width of the packaging box 21. After passing through the guide groove 13, the package 22 can be compressed to a width less than the inner width of the packaging box 21, so as to be better placed in the interior of the packaging box 21. However, the width of the push handle 2 cannot be greater than the width of the guide groove 13, resulting in the corners of the package 22 overflowing between the push handle 2 and the guide groove 13. As a result, when the package 22 is pushed by the push handle 2, the corners of the package 22 are easily stuck in the gap between the side wall of the push handle 2 and the side wall of the guide groove 13, thereby causing the package 22 to be torn.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The following provides a compression cartoning machine, which aims to solve the technical problem that when a soft package 22 with a width greater than the inner width of a packaging box 21 is compressed by a rigid pusher 2 through a guide groove 13 with a width less than the inner width of the packaging box 21 and then pushed into the packaging box 21, the corners of the package 22 overflow between the pusher 2 and the guide groove 13.

[0037] (First embodiment)

[0038] Figure 2 The schematic diagram of the box packing operation of the first embodiment is shown. Figure 2 .

[0039] Compression cartoning machine includes:

[0040] A carrier 1, used for placing packaging 22;

[0041] A guide groove 13 is formed on the carrier 1 and passes through the carrier 1 along the box loading direction, and is used to guide the package 22 to move toward the packaging box 21;

[0042] The first pushing portion 3 is disposed on the opposite side of the packaging box 21 relative to the carrier 1, and is used to push the packaging 22 to move along the guide groove to the inside of the packaging box 21. The width of the first pushing portion 3 is smaller than the width of the guide groove;

[0043] in,

[0044] The guide groove 13 includes a first compression section 14, and the first compression section 14 has two ends with different widths. The width of the end of the first compression section 14 close to the packaging box 21 is smaller than the inner width of the packaging box 21, and the width of the end of the first compression section 14 away from the packaging box 21 is larger than the outer width of the packaging 22.

[0045] The second pushing parts 4 are attached to both sides of the first pushing part 3 in the width direction. When there is no external force, the distance between the ends of the two second pushing parts 4 that are away from each other is greater than the outer width of the packaging 22. The ends of the second pushing parts 4 that are away from each other can move in line with the side wall of the first compression section 14.

[0046] The first pushing part 3 and the second pushing part 4 constitute an improved push handle 2, which can adjust its width automatically according to the width of the first compression section 14, so that the corners of the package 22 are difficult to overflow between the push handle 2 and the guide groove.

[0047] Specifically:

[0048] The carrier 1 is moved to the side of the packaging box 21 by a conveyor (not shown).

[0049] The guide groove 13 at least includes a bottom wall for supporting the bottom of the package 22 , and side walls erected on both sides of the bottom wall for clamping the package 22 .

[0050] The first pushing portion 3 is fixedly connected to the actuator of the cylinder or servo push rod (not shown in the figure) to perform the actions of pushing the packaging object 22 and resetting.

[0051] The second pushing part 4 can be connected to the first pushing part 3 through a variety of structures to achieve the purpose of changing the width of the pushing handle 2. For example, the first pushing part 3 and the second pushing part 4 are connected by a sliding pair 5, so that the second pushing part 4 can slide along its own width direction, and the second pushing part 4 moves toward the first pushing part 3 when moving along the first compression section 14; or, the second pushing part 4 is a compressible flexible material, and the second pushing part 4 compresses itself when moving along the first compression section 14.

[0052] Among them, preferred:

[0053] The first pushing portion 3 and the second pushing portion 4 are connected via a sliding pair 5 , and the first pushing portion 3 and the second pushing portion 4 are located in the same plane toward one side of the packaging box 21 .

[0054] This design allows the middle and corners of the packaging 22 to be pushed into the interior of the packaging box 21 at the same time.

[0055] The guide groove 13 also includes a top wall that presses down the top of the package 22 so that the height of the package 22 is smaller than the inner height of the packaging box 21 .

[0056] This design allows the package 22 whose outer height is greater than the inner height of the package box 21 to be compressed and placed inside the package box 21. The carrier 1 that implements this design includes a bottom plate 11, side plates 12 and a top plate. The top plate is not shown in the figure. The top plate can move up and down relative to the bottom plate 11, so that the distance between the top wall and the bottom wall of the carrier 1 can be adjusted to achieve the purpose of compressing the outer height of the package 22.

[0057] The guide groove 13 also includes a second compression section 15. The first compression section 14 and the second compression section 15 are connected along the box loading direction and pass through the carrier 1. The second compression section 15 includes two ends with the same width. The second compression section 15 is arranged on a side of the carrier 1 close to the packaging box 21. The length of the second compression section 15 in the box loading direction is greater than the length of the first compression section 14.

[0058] After the packaging material 22 is compressed by the first compression section 14 to a width smaller than the inner width of the packaging box 21, it continues to move along the second compression section 15, so that the packaging material 22 is continuously compressed by the longer second compression section 15, so that the packaging material 22 is shaped, thereby reducing the speed of width rebound after the packaging material 22 enters the interior of the packaging box 21, thereby reducing the difficulty of pushing the packaging material 22 into the interior of the packaging box 21.

[0059] On the other hand, in order to achieve the purpose that the second pushing part 4 can reset itself when the pushing handle 2 moves in the opposite direction to the box loading direction, preferably: the first pushing part 3 and the second pushing part 4 are connected by an elastic member, the first pushing part 3 is connected with a stop member 7, the stop member 7 is at least arranged on the side of the second pushing part 4 away from the first pushing part 3, and the stop member 7 is used to prevent the second pushing part 4 from completely separating from the first pushing part 3.

[0060] When the push handle 2 moves in the opposite direction to the box loading direction, the design allows the second push portion 4 to reset itself by the elastic force of the elastic member, and the reset action is completed when the second push portion 4 contacts the stopper 7.

[0061] Other embodiments that can enable the second pushing part 4 to reset itself: a slider is installed at the end of the second pushing part 4, and the side walls of the first compression section 14 and the second compression section 15 are provided with slide rails, and the slider and the slide rails are slidably connected; or, a magnet is installed at the end of the second pushing part 4, and the side walls of the first compression section 14 and the second compression section 15 are provided with iron bars, and the magnet and the iron bars are magnetically adsorbed and connected.

[0062] When the push handle 2 moves in any direction, these two embodiments allow the end of the second pushing portion 4 to always follow the side walls of the first compression section 14 and the second compression section 15 , without the need for an elastic member and a stopper 7 .

[0063] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 The specific structure of using the elastic member and the stopper 7 to automatically reset the second pusher 4 is as follows.

[0064] The first pushing part 3 is an integral part formed by casting, and the second pushing part 4 is an integral part formed by sheet metal.

[0065] The first pushing portion 3 includes: a first plate 31 and a second plate 33, wherein the second plate 33 is symmetrically arranged on both sides of the first plate 31 and fixedly connected to the first plate 31;

[0066] The second pushing part 4 includes: a third plate 41 and a fourth plate 43, and the third plate 41 and the fourth plate 43 are vertically connected;

[0067] The fourth plate 43 is connected to the first plate 31 through the sliding pair 5 and the elastic member, the stopper 7 is arranged on the second plate 33, the fourth plate 43 is located between the first plate 31 and the stopper 7, and an opening for avoiding the second plate 33 is formed on the fourth plate 43;

[0068] The fourth plate 43 is used to determine the position of the third plate 41 . The first plate 31 , the second plate 33 and the third plate 41 are located on the same plane on one side facing the packaging box 21 , and are used together to push the packaging object 22 .

[0069] Other things that need to be explained are:

[0070] A through hole 32 is provided at the center of the first plate 31 and passes through the first plate 31 along the box loading direction. The through hole 32 is used to connect the actuator of the cylinder or the electric push rod.

[0071] The sliding pair 5 includes a guide sleeve 51 fixedly connected to the first plate 31 , and a guide post 52 fixedly connected to the fourth plate 43 . The guide sleeve 51 and the guide post 52 are plugged into each other and are clearance-matched.

[0072] The elastic member includes a spring 6 sleeved on the guide post 52 , and two ends of the spring 6 abut against the first plate 31 and the fourth plate 43 respectively.

[0073] A fifth plate 35 is also provided between the first pushing portion 3 and the second pushing portion 4. The fifth plate 35 is in contact with the side wall of the first plate 31 in the width direction. One end of the spring 6 away from the fourth plate 43 rests on the fifth plate 35. The guide column 52 passes through the fifth plate 35 and is inserted into the interior of the guide sleeve 51.

[0074] The fifth plate 35 functions to disperse the thrust of the spring 6 so that the thrust of the spring 6 does not directly act on the guide sleeve 51 but is dispersed to the first plate 31 through the fifth plate 35 .

[0075] On the other hand, a positioning portion 42 is formed at one end of the third plate 41 away from the first plate 31 and protrudes toward the side wall of the guide groove 13. A positioning groove 16 is formed on the guide groove 13 and is loosely matched with the positioning portion 42. The positioning groove 16 passes through the carrier 1 along the box loading direction.

[0076] The positioning portion 42 and the positioning groove 16 have the function of limiting the height change of the end of the second pushing portion 4 away from the first plate 31 during the operation of the push handle 2 , thereby preventing the first pushing portion 3 from rotating around the axis of the through hole 32 .

[0077] (Second embodiment)

[0078] In the first embodiment, long-term friction between the second pushing portion 4 and the carrier 1 easily causes one of them to wear out. The second embodiment aims to solve this problem.

[0079] Figure 3 The front view of the push handle 2 of the second embodiment is shown, combined with Figure 3 .

[0080] On the basis of the first embodiment, each second pushing portion 4 is connected to a rolling portion 71, and the rolling portion 71 can rotate around its own axis. The axis of the rolling portion 71 is parallel to the side wall of the guide groove 13, and the distance between the farthest ends of the two rolling portions 71 is greater than the distance between the farthest ends of the two second pushing portions 4.

[0081] This design enables the rolling portion 71 to contact the guide groove 13 while the second pushing portion 4 cannot contact the guide groove 13 , and the second pushing portion 4 moves following the rolling portion 71 , thereby reducing the friction between the push handle 2 and the carrier 1 .

[0082] (Third Embodiment)

[0083] In the second embodiment, since the overall size of the push handle 2 is relatively small, the connection structure among the first pushing part 3, the second pushing part 4, the elastic member and the rolling part 71 is relatively compact, which is not convenient for production and assembly. The third embodiment aims to solve this problem.

[0084] Figure 4 Shown Figure 3 The cross-sectional view in the AA direction, Figure 5 A three-dimensional diagram of a push handle 2 of the third embodiment is shown. Figure 6 A three-dimensional diagram of the first pusher 3 of the third embodiment is shown. Figure 4 , 5 、6.

[0085] On the basis of the first embodiment, guide parts are provided on both sides of the first pushing part 3, and each stopper 7 is slidably connected to a guide part, and the guide part is used to move the stopper 7 along the width direction of the first pushing part 3 within a specified stroke.

[0086] Each stopper 7 is connected to a rolling portion 71 which can rotate around its own axis. The axis of the rolling portion 71 is parallel to the side wall of the first compression section 14 . The distance between the farthest ends of the two rolling portions 71 is greater than the distance between the farthest ends of the two second push portions 4 .

[0087] This design enables the stopper 7 and the rolling portion 71 to occupy the same position in space, and there is no need to design separate installation positions for the two, thereby making the structure of the push handle 2 more compact.

[0088] Preferably, the guide portion is an oblong hole 34 provided on the second plate 33 , the stopper 7 is a cylinder inserted into the oblong hole 34 , the rolling portion 71 is a bearing, the stopper 7 is interference fit with the inner ring of the bearing, and the outer ring of the bearing fits the fourth plate 43 .
