Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bag production technology, and in particular to a plastic bag packing mechanism. Background Technology
[0002] After the plastic bags are produced, they are arranged linearly on the conveyor line. The plastic bags need to be picked up manually and put into boxes to hold them. The production line needs to be monitored manually, which is costly. When a plastic bag transfer mechanism is used to pack the plastic bags into boxes, the full boxes still need to be replaced manually and the empty boxes placed in the corresponding workstations. The separation of boxes also requires manual operation, making the process quite cumbersome. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the above-mentioned technical deficiencies by providing a plastic bag packing mechanism. It adopts two sets of drive mechanisms in cooperation with the stacking and separating mechanism. After the stacking and separating mechanism separates the stacked boxes, the boxes are transferred to the corresponding position of the plastic bag transfer mechanism that needs to be packed. Then, the box full of plastic bags is discharged by another drive mechanism. This realizes the replacement of plastic bag boxes without manual intervention, speeds up the production process, and reduces the pressure on the staff.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a plastic bag transfer mechanism, a box packing station corresponding to the plastic bag transfer mechanism, and an empty box station on one side of the box packing station; a box stacking and separating mechanism is provided above the empty box station; it also includes a first driving mechanism for transferring boxes from the empty box station to the box packing station; and a second driving mechanism for transferring boxes out of the box packing station, wherein the movement paths of the first driving mechanism and the second driving mechanism for moving boxes are arranged to intersect.
[0005] To further optimize this technical solution, the first driving mechanism includes a first push rod disposed corresponding to the side of the box and a driving component for driving the first push rod to move.
[0006] To further optimize this technical solution, the second drive mechanism includes a second push rod disposed corresponding to the side of the box and a drive assembly for driving the second push rod to move.
[0007] To further optimize this technical solution, the driving component is a telescopic cylinder.
[0008] Further optimizing this technical solution, the stacking box separation mechanism includes box-separating columns arranged opposite to each other on both sides of the stacked boxes; and a box-separating drive mechanism that drives the box-separating columns to rotate; the box-separating columns are arranged along the stacking direction; the box-separating columns have a box-supporting part and a separation part circumferentially arranged on their protruding outer surfaces, and the separation part is arranged to gradually expand towards the stacking direction along the rotation direction; the separation part has a head and a tail with a gradually increasing thickness along the axial direction; the box-supporting part is arranged lower than the head of the separation part.
[0009] To further optimize this technical solution, the upper surface of the frame section is lower than the upper surface of the tail section of the separation section, and the upper surface of the head section of the separation section is lower than the upper surface of the tail section of the separation section.
[0010] To further optimize this technical solution, the separation section is expanded on both sides along the stacking direction of the boxes.
[0011] To further optimize this technical solution, the dividing columns on both sides of the box are symmetrically arranged; the dividing columns on both sides rotate in opposite directions when they rotate.
[0012] To further optimize this technical solution, the distance between the head of the racking section and the head of the separation section is greater than the height of the upper edge of the box when a single box is placed on the racking section, but less than the distance between the edges of two stacked boxes near the separation column.
[0013] To further optimize this technical solution, the box-splitting drive mechanism is a rack and pinion motion mechanism driven by a motor or cylinder.
[0014] Compared with the prior art, this utility model has the following advantages: by using two sets of drive mechanisms in conjunction with the stacking box separation mechanism, the stacked boxes are separated by the stacking box separation mechanism, and then the boxes are transferred to the corresponding position of the plastic bag transfer mechanism that needs to be packed. Then, the boxes filled with plastic bags are discharged by another drive mechanism, realizing the replacement of plastic bag boxes without manual intervention, speeding up the production progress and reducing the pressure on the staff.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0022] Detailed implementation method: combined with Figure 1-5 As shown, a plastic bag packing mechanism includes a plastic bag transfer mechanism 1, a packing station 2 corresponding to the plastic bag transfer mechanism 1, and an empty box station 3 on one side of the packing station 2; a stacking and separating mechanism 4 is provided above the empty box station 3; it also includes a first driving mechanism 5 for transferring boxes from the empty box station 3 to the packing station 2; and a second driving mechanism 6 for transferring boxes out of the packing station 2. The movement paths of the boxes driven by the first driving mechanism 5 and the second driving mechanism 6 are intersected. The plastic bag transfer mechanism 1 is a clamping plate structure for gripping or grasping plastic bags.
[0023] The first drive mechanism 5 includes a first push rod 7 corresponding to the side of the box and a drive assembly for moving the first push rod 7; the second drive mechanism 6 includes a second push rod 8 corresponding to the side of the box and a drive assembly for moving the second push rod 8. The drive assembly is a telescopic cylinder.
[0024] The stacking box separation mechanism 4 includes box-separating columns 9 arranged opposite to each other on both sides of the stacked boxes; and a box-separating drive mechanism that drives the box-separating columns 9 to rotate; the box-separating columns 9 are arranged along the stacking direction of the boxes; the box-separating columns 9 are circumferentially provided with a box-supporting part 10 and a separation part 11 protruding from their outer surface, and the separation part 11 is arranged to gradually expand along the rotation direction towards the stacking direction of the boxes; the separation part 11 has a head and a tail with a gradually increasing thickness along the axial direction; the box-supporting part is arranged lower than the head of the separation part 11.
[0025] The upper surface of the box-standing section 10 is lower than the upper surface of the tail of the separating section 11, and the upper surface of the head of the separating section 11 is lower than the upper surface of the tail of the separating section 11. The separating section 11 expands on both sides along the stacking direction of the boxes. The separating columns 9 on both sides of the box are symmetrically arranged; the separating columns 9 on both sides rotate in opposite directions when they rotate. The distance between the head of the box-standing section 10 and the separating section 11 is greater than the height of the upper edge of the box when a single box is placed on the box-standing section 10, and less than the distance between the edges of two stacked boxes near the separating column 9. The box-separating drive mechanism is a rack and pinion mechanism driven by a motor or cylinder.
[0026] Combination Figure 1-5 As shown, in operation, initially, neither the empty box station 3 nor the packing station 2 has any boxes. The bottommost box of the stack is separated by the rotation of the box-separating column 9 of the stacking and separating mechanism 4 and falls to the empty box station 3. The first push rod 7 of the first drive mechanism 5 pushes the empty box to the packing position, and plastic bags are put into the empty box of the packing mechanism of the plastic bag transfer mechanism 1. After packing is completed, the second push rod 8 of the second drive mechanism 6 pushes the box with plastic bags out of the packing station 2. Then, the stacking and separating mechanism 4 separates the next empty box, and the cycle is repeated to improve the operating efficiency.
[0027] Combination Figure 1-5 As shown, the specific working process of the stacked box separation mechanism 4 is as follows: the stacked boxes are placed between the two side box separation columns 9. The boxes are supported by the separation part 11 outside the two side box separation columns 9. When the boxes need to fall one by one, the separation column 9 is driven to rotate by the drive mechanism, so that the two sides of the bottom box fall from the separation part 11 to the box support part 10. At this time, the head of the separation part 11 faces the side gap between the two adjacent boxes and continues to rotate, so that the head of the separation part 11 is inserted into the gap between the two adjacent boxes. The boxes on both sides are separated by the gradually expanding shape of the separation part 11. At the same time, the bottom box lacks the support of the box support part 10. The top of the bottom box is pushed down by the separation part 11 and separated from the top box, so that the bottom box can fall freely. At the same time, the top box is supported by the top of the separation part 11 to complete one working cycle. The difference between using a motor or a telescopic cylinder to drive the compartment column 9 to rotate is that the cylinder drives the compartment column 9 to rotate in both directions, while the motor drives the compartment column 9 to rotate in one direction. Both methods can achieve the same result of dropping the box from the separation section 11 to the box rack section 10.
[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0029] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
