Description

Technical Field

[0001] The utility model relates to the technical field of fixture equipment, and particularly relates to a material gripping device. Background Art

[0002] In the production and processing machinery and equipment of wine gift bags, there are often conveying devices such as conveyor belts to convey the produced gift bags. After several processes, they are finally stacked and sealed in boxes.

[0003] When clamping a stack of gift bags and putting them into a sealed box, if only clamping the two sides of a stack of gift bags, since there is no restriction at the bottom, it may cause the gift bags to fall from the bottom of the clamping device during the clamping process, thus unable to complete the complete boxing of a stack of gift bags. And there is currently no clamping device in the prior art for stably clamping a stack of stacked gift bags. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a material gripping device to solve the deficiencies of the prior art. With this solution, while clamping a stack of gift bags or even two stacks of gift bags through the clamping plates, the bottom of the gift bags can be supported by the lifting plate to achieve stable clamping.

[0005] The utility model is realized through the following technical solutions:

[0006] A material gripping device, comprising:

[0007] A bracket, the top of the bracket is provided with a translation track, and the translation track extends outside the bracket;

[0008] A gripping assembly, the gripping assembly is slidably connected to the translation track. The gripping assembly includes two oppositely arranged clamping plates. The gripping assembly further includes a first control unit for controlling the lifting of the two clamping plates and a second control unit for controlling the two clamping plates to approach or move away from each other;

[0009] The clamping plate is further provided with a third control unit, and a lifting plate is rotatably connected to the bottom of the clamping plate. The third control unit is used to drive the lifting plate to rotate to the inside of the clamping plate and be perpendicular to the clamping plate, or to rotate out of the inside of the clamping plate.

[0010] In the prior art, when clamping a stack of gift bags and placing them into a sealed packing box, if only the two sides of a stack of gift bags are clamped, since there is no restriction at the bottom, it may cause the gift bags to fall from the bottom of the clamping device during the clamping process, thus unable to complete the complete packing of a stack of gift bags. And there is currently no clamping device in the prior art for stably clamping a stack of stacked gift bags. The present utility model provides a material gripping device. With this solution, while clamping a stack of gift bags through the clamping plate, the bottom of the gift bags can be supported by the lifting plate to achieve stable clamping. In a specific solution, it includes a bracket and a translation track at the top of the bracket. The translation track extends outside the bracket. In this way, the gripping assembly moves to the outside through the translation track, clamps the stacked gift bags at the gripping station of the stacking machine outside, and then moves inside the bracket and releases them into the temporarily placed sealed packing box inside the bracket to complete the transfer. A roller conveyor device (not shown in the figure) is installed in the space below the bracket to convey the sealed packing box. The gripping assembly is also equipped with a first control unit and a second control unit. The first control unit drives the two clamping plates to move up and down, and the second control unit drives the two clamping plates to move towards or away from each other. The two clamping plates are in a plate shape. In this way, in the limited space remaining inside the sealed packing box, it is convenient to extend into the sealed packing box to complete the release of the gift bags. A lifting plate is also provided at the bottom of the clamping plate. Under the control of the third control unit, the lifting plate can be driven to rotate towards the inner side of the clamping plate until it is perpendicular to the lifting plate. In this way, the bottom of the gift bags can be supported by the lifting plate, thus completing the stable clamping of the stacked gift bags and preventing the gift bags from falling from the bottom. When the clamping plate extends into the sealed packing box, control the lifting plate to reset and rotate out of the inner side of the lifting plate. At this time, there is no restriction on the bottom of the gift bags, and the release of the stacked gift bags can be completed, and the clamping plate is moved upward and out.

[0011] As a specific structure of the third control unit, the third control unit includes a telescopic cylinder and a vertical rod. The upper end of the vertical rod is connected to the output end of the telescopic cylinder. The lower end of the vertical rod is provided with an installation groove, and a horizontal shaft is arranged in the installation groove. The lifting plate is rotationally connected to the horizontal shaft through a torsion spring. The torsion spring is used to apply a torsion force to the lifting plate to rotate towards the inner side of the clamping plate. Both the vertical rod and the lifting plate are located outside the clamping plate. In this solution, through the telescopic movement of the telescopic cylinder, the vertical rod connected to it moves in the vertical direction, and the vertical rod drives the lifting plate to move. During this movement process, when moving downward, the lifting plate gradually gets out of the restriction of the clamping plate and rotates inward under the drive of the torsion spring until the lifting plate is perpendicular to the clamping plate, and then stop driving. When moving upward, the bottom of the clamping plate abuts against the upper side of the lifting plate and presses the lifting plate downward, causing it to rotate outward until the lifting plate is parallel to the clamping plate. At this time, the clamped gift bags can complete the dropping.

[0012] To reduce the overall thickness of the clamping plate and facilitate its insertion into the sealed box in a limited space, the telescopic cylinder is located above the inner side of the clamping plate, with its output end facing upward, and a transverse rod is connected to the output end of the telescopic cylinder; a vertical through groove is also provided at the upper end of the clamping plate, and the upper end of the vertical rod passes through the vertical through groove and is connected to the transverse rod inside the clamping plate. In this solution, the telescopic cylinder is arranged above the inner side of the clamping plate. In this way, the part of the clamping plate below the telescopic cylinder is used to clamp the gift bag. The output end of the telescopic cylinder faces upward, which is convenient for arranging the transverse rod above the telescopic cylinder. The vertical rod is connected through the transverse rod to facilitate the up and down movement of the vertical rod and the blanking plate within the length range of the vertical through groove.

[0013] To achieve stable clamping of stacked gift bags and be able to grab two stacks of gift bags side by side at the same time, a number of blanking plates are evenly distributed along the clamping width direction of the clamping plate. A vertical rod is connected to each blanking plate, and a vertical through groove is provided at the upper end position of each vertical rod. The upper end of each vertical rod passes through the vertical through groove and is connected to the transverse rod inside the clamping plate.

[0014] To hide the vertical rod inside the clamping plate to reduce the overall thickness of the clamping plate, a vertical sliding groove is also provided on the outer side surface of the clamping plate, and the vertical rod is slidably arranged in the vertical sliding groove.

[0015] To adapt to the width of the grabbed gift bag, side baffles are provided on both sides inside the clamping plate.

[0016] To adjust the distance between the two side baffles, a back plate is also provided on the side baffle. The back plate is arranged outside the clamping plate, and a long slot is provided on the back plate. The long slot is connected to the outside of the clamping plate through bolts.

[0017] As a specific setting method of a grasping and clamping component, a long through hole is provided at the top of the bracket, and the translation track includes a first sliding rail arranged on both sides of the long through hole; the grasping and clamping component further includes an intermediate plate and a fixing plate. The intermediate plate is horizontally slidably arranged on the first sliding rails on both sides of the long through hole; the fixing plate is located below the intermediate plate and the long through hole, and the clamping plate is arranged on the fixing plate; the first control unit is fixed on the intermediate plate and is used to drive the lifting of the fixing plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and do not constitute a limitation to the present utility model.

[0031] Embodiment:

[0032] This embodiment provides a material gripping device, as Figures 1-5 shown, including:

[0033] A bracket 301, with a translation track 302 at the top of the bracket 301, and the translation track 302 extends outside the bracket 301;

[0034] A gripping assembly, which is slidably connected to the translation track 302. The gripping assembly includes two oppositely arranged clamping plates 303. The gripping assembly further includes a first control unit for controlling the lifting of the two clamping plates 303 and a second control unit for controlling the two clamping plates 303 to move towards or away from each other;

[0035] The clamping plate 303 is also provided with a third control unit, and a blanking plate 304 is rotatably connected to the bottom of the clamping plate 303. The third control unit is used to drive the blanking plate 304 to rotate inside the clamping plate 303 and be perpendicular to the clamping plate 303, or to rotate out of the inside of the clamping plate 303.

[0036] In the prior art, when clamping a stack of gift bags and placing them into a sealed packing box, if only the two sides of a stack of gift bags are clamped, since there is no restriction at the bottom, it may cause the gift bags to fall from the bottom of the clamping device during the clamping process, thus unable to complete the complete packing of a stack of gift bags. And there is no clamping device in the prior art that can stably clamp a stack of stacked gift bags. The present utility model provides a material gripper device. With this solution, while clamping a stack of gift bags through the clamping plate 303, the bottom of the gift bags can be supported by the lifting plate 304 to achieve stable clamping. In a specific solution, it includes a bracket 301 and a translation track 302 at the top of the bracket 301. The translation track 302 extends outside the bracket 301. In this way, the gripper assembly moves to the outside through the translation track 302, clamps the stacked gift bags at the gripper station of the stacking machine outside, and then moves inside the bracket 301 and releases them into the temporarily placed sealed packing box inside the bracket 301 to complete the transfer. A roller conveyor device (not shown in the figure) is installed in the space below the bracket 301 to convey the sealed packing box. The gripper assembly also has a first control unit and a second control unit. The first control unit drives the two clamping plates 303 to lift and lower, and the second control unit drives the two clamping plates 303 to move closer or farther away from each other. The two clamping plates 303 are plate-shaped. In this way, it is convenient to extend into the sealed packing box to release the gift bags in the limited remaining space inside the sealed packing box. A lifting plate 304 is also provided at the bottom of the clamping plate 303. Under the control of a third control unit, the lifting plate 304 can be driven to rotate towards the inner side of the clamping plate 303 until it is perpendicular to the lifting plate 304. In this way, the bottom of the gift bags can be supported by the lifting plate 304, thus completing the stable clamping of the stacked gift bags and preventing the gift bags from falling from the bottom. When the clamping plate 303 extends into the sealed packing box, control the lifting plate 304 to reset and rotate out of the inner side of the lifting plate 304.

Both the vertical rod 306 and the blanking plate 304 are located outside the clamping plate 303. In this solution, through the telescopic movement of the telescopic cylinder 305, the vertical rod 306 driven by it moves in the vertical direction, and the vertical rod 306 drives the blanking plate 304 to move. During this movement, when moving downward, the blanking plate 304 gradually breaks away from the restriction of the clamping plate 303 and rotates inward under the drive of the torsion spring until the blanking plate 304 is perpendicular to the clamping plate 303, and then the drive stops. When moving upward, the bottom of the clamping plate 303 abuts against the upper side of the blanking plate 304 and presses the blanking plate 304 downward, causing it to rotate outward until the blanking plate 304 is parallel to the clamping plate 303, and at this time, the clamped gift bag can complete the drop.

In this way, the part of the clamping plate 303 below the telescopic cylinder 305 is used to clamp the gift bag. The output end of the telescopic cylinder 305 faces upward, which is convenient for arranging the horizontal rod 308 above the telescopic cylinder 305, and connecting the vertical rod 306 through the horizontal rod 308 to facilitate the up and down movement of the vertical rod 306 and the blanking plate 304 within the length range of the vertical through groove.
