Description

Technical Field

[0001] The utility model relates to a component on a cartoning machine, in particular to a special-shaped gripping head mechanism of the cartoning machine. Background Art

[0002] Cartoning machines are packaging equipment that put daily necessities, industrial products, food, medicine bottles and other materials into paper boxes for packaging. Especially in the packaging process of long strips of materials, it is necessary to grab the materials in the material pile and transfer the materials to the designated location for sorting or direct boxing. The existing way of grabbing materials is through manual grabbing. In the process of mass production, the labor intensity is extremely high, which is difficult for workers to cope with and greatly increases the cost of production. If ordinary robots are used, the materials may fall during the transfer process. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a special-shaped gripping head mechanism of a cartoning machine which can reliably grip strip-shaped materials, thereby improving the cartoning efficiency of the materials.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special-shaped gripper mechanism of a cartoning machine, comprising a connecting head, a fixing seat with an "n"-shaped cross-section connected to the bottom of the connecting head, a bidirectional slide cylinder installed in the inner cavity of the fixing seat, and two sealing plates, the side walls of the fixing seat are respectively connected to a sealing plate through a parallelogram mechanism, so that the sealing plate can be guided up and down, two rotating shafts close to each other and symmetrical are arranged in the fixing seat, rotatable grippers are respectively installed on the two rotating shafts, one side of the two grippers respectively has an arc-shaped hook claw, the number of the hook claws is at least two, the hook claws between the two grippers are staggered, and the other side of the two grippers is respectively provided with a hinged part, the hinged part is transmission-connected to the output end of one side of the adjacent bidirectional slide cylinder through a hinged rod, the output end of the bidirectional slide cylinder is transmission-connected to the adjacent parallelogram mechanism, driving the sealing plate to move up and down, when the output end of the bidirectional slide cylinder outputs, the two grippers embrace each other to form a support ring with an upper opening, and at the same time the sealing plate moves down to block the end opening of the support ring.

[0005] The parallelogram mechanism includes two "7"-shaped connecting rods rotatably mounted on the outer side wall of the fixed seat. The two "7"-shaped connecting rods are vertically arranged up and down. The ends of the two "7"-shaped connecting rods are respectively connected to the sealing plates. The output end of the bidirectional slide cylinder and the bending part of the "7"-shaped connecting rod are movably connected through a hinged connecting rod.

[0006] The beneficial effect of the utility model is that the output ends on both sides of the bidirectional slide cylinder output simultaneously, which will drive the two grippers to grab the strip-shaped materials. At the same time, the sealing plate moves down to block the two side ports of the support ring formed by the two grippers, which can effectively prevent the strip-shaped materials from escaping from the grippers during movement, thereby improving the stability and reliability of material grabbing, thereby improving the efficiency of material boxing.

[0011] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0012] like Figure 1 — Figure 3 As shown, this embodiment discloses a special-shaped gripping head mechanism of a cartoning machine, including a connecting head 1, which is generally connected to a sliding seat of a linear motion module through a lifting cylinder, and a fixed seat 2 with an "n"-shaped cross-section is connected below the connecting head 1. A two-way slide cylinder 3 is installed in the inner cavity of the fixed seat 2. The two-way slide cylinder 3 has two output ends that can be telescoped simultaneously, and each output end has two piston rods, and the piston rods are connected to the slide 31. The two-way slide cylinder 3 is connected to the air pump through an electromagnetic valve, and the electromagnetic valve can control the telescopic action of the two-way slide cylinder 3, and also includes two sealing plates 4. The side walls of the fixed seat 2 are respectively connected to a sealing plate 4 through a parallelogram mechanism 5, so that the sealing plate 4 can be guided up and down to fix. Two mutually close and symmetrical rotating shafts 6 are arranged in the seat 2, and rotatable grippers 7 are respectively installed on the two rotating shafts 6. One side of the two grippers 7 respectively has an arc-shaped hook claw 71, and the number of the hook claws 71 is at least two. The hook claws 71 between the two grippers 7 are staggered with each other, and the other sides of the two grippers 7 are respectively provided with a hinge part 72, and the hinge part 72 is transmission connected with the output end of one side of the adjacent two-way slide cylinder 3 through a hinge rod 73. The output end of the two-way slide cylinder 3 is transmission connected with the adjacent parallelogram mechanism 5, driving the sealing plate 4 to move up and down. When the output end of the two-way slide cylinder 3 is output, the two grippers 7 embrace each other to form a support ring with an upper opening, and at the same time, the sealing plate 4 moves down to block the end opening of the support ring.

[0013] The parallelogram mechanism 5 includes two "7"-shaped connecting rods 8 rotatably mounted on the outer side wall of the fixed seat 2. The two "7"-shaped connecting rods 8 are vertically arranged up and down. The end parts of the two "7"-shaped connecting rods 8 are respectively connected to the sealing plate 4. An articulated connecting rod 9 is movably connected between the output end of the double-sided slide cylinder 3 and the bent part of the "7"-shaped connecting rod 8. One side of the two "7"-shaped connecting rods 8 is connected to the fixed seat 2, and the other side is connected to the sealing plate 4, thus forming the parallelogram mechanism 5. The sealing plate 4 can only move up and down under the restriction of the two "7"-shaped connecting rods 8. After the output end of the double-sided slide cylinder 3 drives one "7"-shaped connecting rod 8 to swing through the articulated connecting rod 9, it will naturally drive the sealing plate 4 to move vertically.

[0014] With the above technical solution, in the initial state, the two grippers are in an open state. When grasping the material, after the output ends on both sides of the double-sided slide cylinder 3 output simultaneously, it will drive the two grippers 7 to grasp the strip-shaped material. At the same time, the sealing plate 4 moves down to block both side ports of the two grippers 7 to form a retaining ring, which can effectively prevent the strip-shaped material from detaching from the grippers 7 during movement, improving the stability and reliability of material grasping, and thus improving the efficiency of material boxing.

[0015] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
