[0021] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides a beer barrel spear automatic fastening device, referring to Figures 1 to 3 As shown, it includes a frame 1, on which a beer keg conveyor belt 2 is provided horizontally. The beer keg conveyor belt 2 is part of the entire beer filling production line, that is, the equipment can be directly installed on the conveyor belt of the production line. Several groups of beer keg fixing devices 3 are provided along the beer keg conveyor belt 2. Each group of beer keg fixing devices 3 is provided with clamping arms 32 on the left and right sides of the beer keg conveyor belt 2. The clamping arms 32 are used to position and clamp the beer kegs conveyed through the beer keg conveyor belt 2 to prevent the kegs from moving and rotating when tightening the beer spears. A beer spear tightening device 4 is provided above the beer keg conveyor belt 2. The specific structure of the beer spear tightening device 4 can be found in the accompanying drawings. Figure 6As shown in the figure, it includes a lifting mechanism 41 arranged on the rack 1. The lifting mechanism 41 can be driven by a motor, a cylinder or hydraulic pressure and move up and down in the vertical direction. A number of vertically downward tightening heads 42 are provided on the lifting mechanism 41. The positions of the tightening heads 42 in the vertical direction should correspond to those of the beer barrel fixing devices 3 respectively, that is, one tightening head 42 is arranged above each group of beer barrel fixing devices 3. The lower end of the tightening head 42 has a vertically downward flared opening. A number of servo motors 43 are provided on the lifting mechanism 41, and each tightening head 42 can be driven by the servo motor 43 to rotate axially. Behind each group of beer fixing devices 3, that is, on the rear side along the running direction of the beer barrel, an automatic barrel blocking device 5 is provided. The automatic barrel blocking device 5 is used to block the beer barrels running with the beer barrel conveyor belt 2 within the working range of the beer barrel fixing device 3. The working process of this device is as follows: The beer barrel runs with the beer barrel conveyor belt 2 to the equipment working area. The automatic barrel blocking device 5 is in the barrel blocking working state. After the beer barrel is blocked, the clamping arms 32 on both sides of the beer barrel conveyor belt 2 move inward to clamp and fix the beer barrel. The lifting mechanism 41 in the spear fastening device 4 drives the tightening head 42 to move downward. The lower end of the tightening head 42 is vertically aligned with the beer barrel spear. The inner surface of the flared opening at the lower end of the tightening head 42 presses against the upper end of the spear from top to bottom. The downward pressing stroke of the lifting mechanism 41 can be preset so that the tightening head 42 can firmly press against the upper end of the spear stably. The servo motor 43 drives the tightening head 42 to rotate, and the tightening head 42 screws the spear into the thread of the barrel neck through the action of friction. In order to increase the friction between the tightening head 42 and the spear, in a preferred embodiment, the inner surface of the tightening head 42 is provided with a non-rigid cushion layer that can increase friction, such as materials like rubberized fiber board or rubber. After the spear is fastened, the lifting mechanism 41 lifts upward, and the clamping arms 32 and the automatic barrel blocking device 5 reset and withdraw from the clamping and barrel blocking states, and the beer barrel continues to be transported backward by the beer barrel conveyor belt 2 for further work. When the number of beer barrel fixing devices 3 and spear fastening devices 4 is multiple groups, sensors and controllers can be set to control the actions of each component. In practical applications, generally one or two groups are set at the same time to avoid interference between their operations.

[0023] The function of the beer barrel fixing device 3 is to position the beer barrel under the tightening head 42 through the clamping arms 31 on both sides of the beer barrel conveyor belt 2 and hold it tightly. The structure of the clamping arm 31 can be in various forms, such as a splint structure that translates from the left and right sides to the middle, a robotic arm with claws, etc. The present invention provides a preferred structure of the beer barrel fixing device 3. Refer to Figure 4 and Figure 5As shown in the figure, on each side of the beer barrel conveyor belt 2, a pair of drive shafts 32 are symmetrically arranged on both left and right sides of each set of beer barrel fixing devices 3. The drive shafts 32 are arranged vertically. Each pair of drive shafts 32 are close to each other and can rotate reciprocally along the axial direction. The two drive shafts 32 in each pair rotate synchronously and in opposite directions. The inner ends of each clamping arm 31 are respectively fixedly connected to the drive shafts 32. The clamping arms 31 connected to each pair of drive shafts 32 are distributed in pairs. The outer ends of each pair of clamping arms 31 extend in a V shape horizontally towards the beer barrel conveyor belt 2. When the drive shafts 32 rotate, they drive the paired clamping arms 31 to close inwards or separate outwards. Since the drive shafts 32 on both sides of the beer barrel conveyor belt 2 are symmetrically arranged, when the drive shafts 32 rotate, the clamping arms 31 on both sides close or separate synchronously. The number of clamping arms 31 connected to each drive shaft 32 is preferably two, and they are distributed parallel to each other vertically, which can make the fixation of the beer barrel more stable. The outer ends of the clamping arms 31 are provided with cylindrical clamping blocks 33 along the vertical direction. The clamping blocks 33 are fixedly connected to the clamping arms 31. When the clamping arms 31 rotate inwards, the clamping blocks 33 press against the outer circumferential surface of the beer barrel. The two clamping arms 31 on both sides act together to fix the beer barrel in the middle. In order to increase the friction between the clamping blocks 33 and the beer barrel, the outer surface of the clamping blocks 33 is provided with a soft cushion layer, such as rubber or other materials.

[0024] In a preferred embodiment, referring to Figure 4 As shown in the figure, at the lower ends of each drive shaft 32, a transmission gear 34 is fixedly connected radially. The transmission gears 34 corresponding to each pair of drive shafts 32 mesh with each other. Each pair of transmission gears 34 includes a driving gear 341 and a driven gear 342. When the driving gear 341 rotates, it can drive the driven gear 342 to rotate synchronously and in opposite directions, thereby driving the clamping arms 32 on the drive shaft 34 to rotate synchronously to the two sides or towards the middle around the drive shaft 34. Further, the driving gears 341 in the two pairs of transmission gears 34 corresponding to the left and right sides of the beer barrel conveyor belt 2 are respectively located at the front side and the rear side. A connecting rod 35 is provided between the two driving gears 341. A clamping cylinder 36 is provided on the frame 1. One of the driving gears 341 is driven by the clamping cylinder 36 to rotate reciprocally, and drives the other driving gear 341 to rotate synchronously and in the same direction through the connecting rod 35. This transmission structure only requires one power source for each set of beer barrel fixing devices 3, and can effectively ensure that the clamping arms 32 on both sides of the beer barrel conveyor belt 2 rotate synchronously and at the same angle, so as to fix the beer barrel better in the middle position.

[0025] In a preferred embodiment, the structure of the automatic barrel blocking device 5 is referred to Figure 2 and Figure 7As shown in the figure, it includes a barrel blocking column 51. There is a gap in the middle of the beer barrel conveyor belt 2. The barrel blocking column 51 can extend upward through the gap from below the beer barrel conveyor belt 2. Specifically, the automatic barrel blocking device 5 includes a rotating shaft 52 that is perpendicular to the running direction of the beer barrel conveyor belt 2 in the horizontal direction. The rotating shaft 52 is located below the beer barrel conveyor belt 2. The barrel blocking column 51 is fixedly connected to the rotating shaft 52 through a connecting plate 53. The rotating shaft 52 is driven by a cylinder to rotate reciprocally. When the rotating shaft 52 rotates, the barrel blocking column 51 extends upward or retracts downward. The rotating shaft 52 rotates reciprocally at a 90° angle. When the barrel blocking column 51 stands up, it blocks the beer barrel. When the barrel blocking column 51 lies flat, the beer barrel is normally conveyed backward on the beer barrel conveyor belt 2. The transmission structure of this automatic barrel blocking device 5 is simple and efficient, and it is easy to cooperate with the actions of other components. To prevent beer barrels from being conveyed into the working area from the front end of the transmission line during the process of fastening the spear, a set of automatic barrel blocking devices 5 can also be set at the front end of the beer barrel conveyor belt 2 to control the front and rear intervals of the beer barrels.

[0026] Compared with the prior art, the automatic beer barrel spear fastening equipment provided by this utility model has a simple structure, reasonable design, and high automation. It can automatically block the barrel, position and fix the beer barrel, and rotate and fasten the spear by friction between the tightening head and the spear under the condition that the beer barrel transmission line runs continuously. It is applicable to the filling production line operation of stainless steel beer barrels, can effectively improve production efficiency and quality, reduce labor costs, and lower safety risks.

[0027] In summary, the automatic beer barrel spear fastening equipment of this utility model can effectively solve the problems of low working efficiency, high labor cost, and inapplicability to automated production line operations in the manual fastening method of the spear of existing stainless steel beer storage barrels. It has high utilization value and practical significance and can be widely promoted and applied.

[0028] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
