Description

Technical Field

[0001] The utility model relates to the technical field of bag stacking clamps, in particular to a bag stacking clamp. Background Art

[0002] The palletizer is a machine that automatically stacks cartons that have been loaded into containers on pallets or pallets (wood, plastic) in a certain arrangement. It can stack multiple layers and then push them out for forklifts to transport them to warehouses for storage. This equipment uses PLC+touch screen control to achieve intelligent operation and management, which is simple and easy to master. It can greatly reduce labor and labor intensity. The palletizer is a machine that automatically stacks bags, cartons or other packaging materials delivered by the conveyor into stacks according to the working method required by the customer's process, and transports the stacked materials.

[0003] In the prior art, when stacking bagged items, hydraulically controlled grippers are often used to grab them. This gripper method is likely to cause the bagged items to fall when transporting the bagged items, and is likely to cause the bagged items to deform when gripping the bagged items, which is not conducive to stacking the bagged items.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] Please refer to 1-3, a bag stacking clamp includes: a supporting sleeve 1, two supporting sleeves 1 are arranged symmetrically, a rack 3 is slidably arranged in the supporting sleeve 1, a clamping claw 2 is arranged on each side of the supporting sleeve 1, and the supporting sleeve 1 and the clamping claw 2 are connected through the rack 3, the rack 3 is meshed with a gear 5, the lower end of the gear 5 is fixedly connected to a screw rod 6, the lower end of the screw rod 6 is threadedly connected to a second nut 8, the bottom end of the second nut 8 is fixedly connected to a stabilizing plate 9, two limit rods 10 are fixedly connected to the stabilizing plate 9, and the two limit rods 10 are slidably arranged on one supporting sleeve 1 respectively.

[0023] Specifically, the rack 3 slides in the supporting sleeve 1, thereby making the supporting sleeve 1 and the clamping jaw 2 integrated, and the supporting sleeve 1 is driven to move by the stacker, thereby changing the position of the clamping jaw 2. The utility model replaces the hydraulic clamp with a parallel sliding clamp, so that the clamping jaw 2 lifts the bag, and no longer uses the squeezing clamping method to avoid bag deformation, and simultaneously drives the two clamping jaws 2 to slide and the stabilizing plate 9 to move in the vertical direction through the gear 5, so that when the bag is lifted by the two clamping jaws 2, it is pressed against the stabilizing plate 9 to complete the fixation of the bag, and the position of the stabilizing plate 9 and the number of rotations of the gear 5 can be adjusted to clamp bags of different specifications, thereby expanding the scope of application of the clamp.

[0024] Furthermore, a force bar 4 is fixedly connected to the clamping jaw 2 , and the force bar 4 is slidably arranged in the supporting sleeve 1 .

[0025] Specifically, the two ends of the two support sleeves 1 are not aligned, but are separated by a distance. Figure 1 Looking down from a high place, the two supporting sleeves 1 are symmetrical about the center of the circle of the gear 5. The two ends of the supporting sleeve 1 are slidably connected with a rack 3 at one end close to the gear 5, and the force bar 4 can be inserted into the end away from the center of the circle of the gear 5. When the gear 5 rotates, the rack 3 is driven to slide in the supporting sleeve 1, and then the two clamping jaws 2 approach each other, so that the force bar 4 fixedly connected to the clamping jaw 2 is inserted into the supporting sleeve 1, so that the clamping jaw 2 and the supporting sleeve 1 are supported by the two racks 3 and the two force bars 4, which greatly increases the load-bearing capacity of the clamping jaw 2 and improves the stability of the clamping jaw 2 when transporting bags.

[0026] Furthermore, an arc-shaped notch 14 is formed on the supporting sleeve 1 , and the gear 5 is meshed with the rack 3 in the arc-shaped notch 14 .

[0027] Specifically, refer to Figure 2 The arc groove 14 is an arc groove opened on the support sleeve 1 around the center of the gear 5. The rack 3 sliding in the support sleeve 1 exposes the tooth groove at the position of the arc groove 14 and meshes with the gear 5, and then the two racks 3 are driven to slide in the support sleeve 1 through the gear 5.

[0028] Furthermore, a limiting sleeve 11 is fixedly connected to the side surface of the supporting sleeve 1 , and the top ends of the two limiting rods 10 respectively pass through a limiting sleeve 11 .

[0029] Specifically, refer to Figure 1 The limiting sleeve 11 is fixedly connected to the side of the supporting sleeve 1, and a slot is opened on the stabilizing plate 9 for the limiting rod 10 to pass through. After the top end of the limiting rod 10 continues to pass through the limiting sleeve 11, the end of the limiting rod 10 is fixed to the stabilizing plate 9 with a screw, so that when the gear 5 rotates, the limiting rod 10 fixes the stabilizing plate 9 and the supporting sleeve 1, thereby preventing the second nut 8 from rotating with the screw rod 6, thereby realizing the vertical movement of the stabilizing plate 9.

[0030] Furthermore, a mounting plate 12 is fixedly connected to the support sleeve 1 , a driving source 13 is mounted on the mounting plate 12 , and an output shaft of the driving source 13 is fixedly connected to the gear 5 .

[0031] Specifically, the gear 5 is powered by a driving source 13 , which includes a motor and a reducer, and can accurately control the rotation direction of the servo motor output shaft, thereby enabling the two clamps 2 to lift and put down the bag.

[0032] In this utility model, reference is made to Figures 1 to 3 , the driving source 13 drives the gear 5 to rotate clockwise, and the gear 5 drives the rack 3 to slide in the supporting sleeve 1, so that the two clamping jaws 2 are close to each other to lift the bag, and at the same time, the screw rod 6 and the second nut 8 are separated, so that the stabilizing plate 9 is pressed against the upper side of the bag, and then the palletizer drives the supporting sleeve 1 to move. When the supporting sleeve 1 is located above the bag stacking, the gear 5 is driven to rotate counterclockwise, so that the two clamping jaws 2 are separated from each other, and the stabilizing plate 9 is gradually close to the screw rod 6, so that the bags are stacked in the bag concentration area.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
