Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a bag-taking device with an adjustable suction cup mechanism. Background Technology

[0002] The bag-picking device is the core mechanism of the automatic bag feeding system in a packaging machine. The flatness of the packaging bag directly affects the success rate of bag picking and is also an important indicator of the overall production efficiency of the packaging unit. Generally, the suction cup of the bag-picking mechanism is designed to be perpendicular to the packaging bag based on the angle at which the packaging bag is placed. For example, patent publication number CN 221316920 U discloses a bag-picking device in the field of food packaging machinery technology. It includes a worktable for placing stacked packaging bags, a support, a vertical telescopic component installed on the support, a negative pressure suction cup, a flexible connecting belt with one end connected to the frame and the other end connected to the negative pressure suction cup, and a moving mechanism for driving the support to move horizontally to the bag-supporting mechanism. The output end of the vertical telescopic component is vertically upward, and the upper end of the output end of the vertical telescopic component contacts the lower side of the middle of the flexible connecting belt. The negative pressure suction cup is located directly above the worktable.

[0003] While the aforementioned bag-picking device effectively solves the problem of displacement caused by squeezing the packaging bag during suction cup bag picking, when there are many stacked packaging bags, the bottom of the bag holder will be set in a raised state to ensure that the upper layer of packaging bags are flat. At the same time, as the number of bags decreases, the lower layer of bags will bulge in the middle and tilt downwards on both sides. Therefore, the suction cup cannot be perpendicular to the bag when picking up the bag, which will lead to bag picking failure and reduce the production efficiency of the packaging unit.

[0004] Therefore, how to ensure that the bag-removing suction cup adapts to the perpendicularity of the packaging bag surface to improve bag-removing stability is the problem that this utility model needs to solve. Utility Model Content

[0005] The purpose of this invention is to overcome the defects and shortcomings of the existing technology and provide a bag-removing device with an adjustable suction cup mechanism, thus solving various problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bag-retrieving device with an adjustable suction cup mechanism includes a bracket, on which a reciprocating bag-retrieving assembly is mounted. The bag-retrieving assembly includes a movable base plate, the guide movement of which is driven by a transmission belt on one side of the bracket. A bag-retrieving cylinder is mounted on the base plate, and a connecting plate is mounted on the piston rod extension end of the bag-retrieving cylinder. Two sets of symmetrically arranged and position-adjustable suction cups are mounted on the connecting plate via a floating joint. The two sets of suction cups form an angle "α" between them, and the angle "α" is adjustable.

[0008] The bracket includes a U-shaped groove component, with end plates welded to both ends of the groove component. Several reinforcing ribs are arranged at intervals inside the groove component. A guide rail is installed on the lower side of the groove component, and a drag chain is installed on the upper side of the groove component.

[0009] A motor mounting plate is installed on the left outer side of the grooved component, and the motor is fixedly mounted on the motor mounting plate. A drive wheel is installed on the output shaft of the motor, and a driven wheel is installed on the right outer side of the grooved component. The drive wheel and the driven wheel are connected by a transmission belt, and a position sensor is installed on the concave plane of the grooved component on the side where the transmission belt is located.

[0010] The base plate is an irregularly shaped plate with two sliders mounted on one side. The sliders slide in a guide rail. A connecting seat is welded to the front of the base plate. The connecting seat is fixedly connected to the transmission belt through a pressure plate. An induction bracket is mounted on the upper side of the pressure plate.

[0011] The guide rod end of the bag-retrieving cylinder is equipped with a connector, the front end of which is connected to the connecting plate. Two guide sleeves are set on both sides of the bag-retrieving cylinder, the bottom end of which is connected to the bottom plate. A guide rod is set through the guide sleeve, and the lower end of which is connected to the connecting plate. A drag chain connecting bracket is installed at the upper end of the bag-retrieving cylinder. The lower end of the drag chain connecting bracket is connected to the moving end of the drag chain.

[0012] Several floating joints are installed on the right side of the connecting plate. The floating joints are installed in a spherical position, and are mounted on the connecting plate using two ball cups. A suction cup is installed at the lower end of the floating joint.

[0013] The angle “ɑ” formed between the two sets of suction cups is 5-15°.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model has a reasonable structural design. It uses a floating joint to install two sets of suction cups, and the angle between the two sets of suction cups can be adjusted as needed. This allows for adjustment based on the condition of the upper surface of the packaging bags on the stack, ensuring that the suction cups are always perpendicular to the packaging bags. This solves the problem of low bag removal rate caused by uneven stack surfaces. Attached Figure Description

[0029] The mechanical component, bracket 1, includes: a U-shaped channel component 100, with a right end plate 101 welded to the right end and a left end plate 102 welded to the left end; several reinforcing ribs 103 welded to the inner side in sections; a guide rail 106 installed on the lower side of the channel component 100; a left limiting block 104 and a right limiting block 105 installed at both ends of the guide rail; a drag chain 107 installed on the upper side of the channel component 100; and a motor mounting plate 1 installed on the outer left end of the channel component 100. 08. The motor 109 passes through the slotted part 100 and is fixed on the motor mounting plate 108. A drive wheel 110 is mounted on the output shaft of the motor 109. A fixed seat 113 is mounted on the right side of the outer side of the slotted part 100. A driven wheel 112 is provided on the fixed seat 113. A transmission belt 111 is mounted on the drive wheel 110 and the driven wheel 112. There are several oblong holes on the concave plane of the slotted part 100, and position sensors 214 are installed in the oblong holes at both ends.

[0030] The bag-retrieving assembly 2 in the mechanical part includes: a base plate 200, which is an irregularly shaped plate mounted on two sliders 206. The sliders 206 are mounted on guide rails 106. Ribs 201, upright plates 202, and end plates 203 are welded to the front side of the base plate 200. The ribs and upright plates are perpendicular to the end plates of the base plate 200 and horizontally positioned at the upper ends of the upright plates and end plates. A transmission belt 111 is fixed to the end plate 203 by a pressure plate 204. A sensing bracket 205 is installed on the upper side of the pressure plate 204. A bag-retrieving cylinder 207 is installed on the upper rear side of the base plate 200. A connector 209 is installed on the guide rod end of the bag-retrieving cylinder 207. The front end of the connector 209 is connected to a connecting plate 210. Two... A guide sleeve 215 is connected to the base plate 200. A guide rod 208 passes through the guide sleeve, and its lower end is connected to the connecting plate 210. A drag chain connecting bracket 213 is installed at the tail of the upper cylinder of the bag-picking cylinder 207. The lower end of the drag chain connecting bracket 213 is connected to the moving end of the drag chain 107. Several floating joints 211 are installed on the right side of the connecting plate 207. The floating joints 211 are installed in a spherical position and are fixed to the lower end of the floating joints 211 by two upper and lower ball cups 216. Suction cups 212 are installed at the lower end of the floating joints 211, and the two sets of suction cups 212 form an angle "α". The angle "α" can be adjusted according to the bag stacking status. The angle of the angle "α" is 5-15°, and the optimal angle is 10°.

[0031] See Figures 1 to 7 In this utility model, a bag-retrieving device with an adjustable suction cup mechanism operates by rotating the motor 109 clockwise under the control of the control system. This rotation drives the drive wheel 110 to rotate, which in turn drives the transmission belt 111 to rotate. The transmission belt 111 then moves the bag-retrieving assembly 2 to the left. Figure 7It can be seen that: the bag-picking assembly 2 is connected to the slider 206 via the base plate 200, and to the transmission belt 111 via the pressure plate 204. When the sensing bracket 205 is in contact with the position sensor 214 on the left, it stops rotating. At the same time, the guide rod of the bag-picking cylinder 207 extends, driving the bag-picking assembly 2 downward until the lower end of the suction cup 212 adheres to the packaging bag and adsorbs it. Simultaneously, the guide rod of the bag-picking cylinder 207 retracts, lifting the bag-picking assembly 2 upward and removing the packaging bag from the bag magazine. When the bag-picking assembly 2 rises to the set height, the motor 109 rotates counterclockwise, driving the transmission belt 111 to rotate counterclockwise, moving the transmission assembly 2 to the right along the guide rail 106 to the bag opening position of the bag feeding machine. At this time, the suction cup 212 places the packaging bag in the bag opening position. Under the control of the program, the above actions are repeated continuously to pick up bags.

[0032] In summary, by adjusting the relative installation positions of the floating connector 211 and the two upper and lower ball cups 216, the included angle between the two sets of suction cups can be adjusted. This allows for adjustment based on the condition of the upper surface of the packaging bags on the stack, ensuring that the suction cups remain perpendicular to the packaging bags. This solves the problem of low bag removal rate caused by uneven stack surfaces.
