Description

Technical Field

[0001] The utility model belongs to the technical field of industrial cup separating equipment, and in particular relates to an industrial cup stacking and cup separating machine. Background Art

[0002] In the field of precision casting, quantitative feeding is the pre-process of the casting process. In the quantitative feeding process, the alloy raw materials need to be placed in the material cup according to the set weight. Each mold casting process requires a feeding cup. The most primitive quantitative feeding method is to use manual weighing and loading, and then neatly place the stacks of filled material cups on the turnover car and push them to the casting workshop. After the casting process is completed, the empty material cups are manually collected, and the cycle is repeated.

[0003] With the continuous improvement of the degree of automation, quantitative combination scales have been introduced to replace manual weighing, but the subsequent processes of cup separation and loading still rely mainly on manual labor. The reason is that the process of "cup separation" is very difficult. Cup separation devices in the prior art are mostly found in the field of food packaging, such as using a vacuum suction method or a fork structure to separate food cups. The vacuum suction method is only limited to loosely stacked cups, and the fork structure is more commonly used in the food industry. For example, the Chinese patent with application number 202220324448.9 provides a vertical pressure mechanism, a cup separation mechanism for beverage packaging, and a filling and sealing machine. The technical solution provides a method of using a fork structure to pull down the cup body at the bottom of the stacked cups, thereby completing the cup separation. There is a huge difference between the cup separation method of the above technical solution and the cup separation method used in the foundry industry: the cup body used for food is often light, thin and disposable, and the cup edge and cup body will have printed and embossed decorative structures, which makes the friction between the cup bodies of the stacked food cups not very large, and they can be separated using a simple fork structure. However, the material cups used in the foundry industry have a certain thickness and strength because they need to hold metal raw materials, and due to frequent turnover, the surface of industrial material cups is often old and rough. In addition, in order to save turnover space and reduce the number of turnovers, workers will press the stacked material cups as hard as possible when stacking them to make as many empty material cups as possible turn over at one time, which will cause the material cups to be pressed particularly tightly and the friction is huge, and it is difficult for ordinary fork structures to separate the cup bodies.

[0004] The stacked cups are separated manually one by one and then put into the weighing plate holes at a time. This is not only labor-intensive but also has low production efficiency, which has become a restrictive factor for the low efficiency of the quantitative feeding section. Summary of the invention

[0005] The utility model aims to provide an industrial cup stacking and separating machine, aiming to solve the technical problem that the prior art cannot be applied to industrial cup stacking and separating and the efficiency of manual cup separation is low.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] An industrial cup stacking and separating machine comprises a feeding assembly, a cup separating assembly and a cup dropping and clamping assembly; the feeding assembly comprises a cup dropping channel, a limiting cylinder, a limiting slide and a limiting slide cylinder connected to the limiting slide for feeding the stacked cups, the limiting cylinder is a hollow structure, and its cavity is arranged below the cup dropping channel; the limiting slide is arranged below the limiting cylinder, the inner diameters of the cup dropping channel and the limiting cylinder are adapted to the caliber of the stacked cups, the stacked cups enter the industrial cup stacking and separating machine through the cup dropping channel, and are restricted by the limiting cylinder and the limiting slide to be fixed at an initial position, and at least three overlapping cup bodies at the bottom of the stacked cups are exposed in the interval between the bottom of the cup dropping channel and the top of the limiting cylinder;

[0008] The cup separation assembly is arranged on the peripheral side of the feeding assembly, the limiting slide is pulled out from the bottom of the stacked cups under the drive of the limiting slide cylinder, and then the cup separation assembly separates the outermost cup body of the stacked cups that falls into the feeding assembly from other cup bodies;

[0009] The cup dropping clamping assembly includes a cup dropping clamping claw and a clamping mechanism cylinder connected thereto. The cup dropping clamping claw is arranged below the limiting slide. When the outermost cup body of the stacked cups is separated from the other cup bodies, the separated cup body falls into the cup dropping clamping claw under the action of gravity and is sent to the subsequent workstation driven by the clamping mechanism cylinder.

[0010] The industrial cup stacking and separating machine in the utility model uses a loading component to limit the stacked cups according to the characteristics of industrial material cups, accurately separates the cup body at the bottom of the stacked cups through the cup separating component, receives the separated dropped cups through the cup dropping clamping component, and then sends the dropped cups to the next process. The industrial cup stacking and separating machine in the utility model realizes the full automation of the cup separation process, and can be used in conjunction with the cup separating machine in the utility model regardless of the quantity and method of stacked cup feeding (automatic cup feeding or manual cup feeding). Furthermore, during the turnover of the material cups, the operator can press the stacked cups as tightly as possible to make as many material cups as possible turn over at one time. The cup separating machine in the utility model can effectively separate the stacked cups without worrying about the problem of difficulty in cup separation, which not only directly improves the efficiency of the cup separation process, but also indirectly reduces the number of turnovers of the material cups, realizing fully automated production and manufacturing.

[0011] Preferably, the cup drop channel comprises a U-shaped channel and a hollow cylindrical channel connected to each other. The cup inlet end of the cup drop channel is set as an open U-shaped channel, which is convenient for inserting the stacked cups into the channel, and the hollow cylindrical channel immediately following ensures that the stacked cups fall into the initial position.

[0012] Preferably, the cup separation assembly comprises a first clamping block chute, and a first clamping block group arranged in the first clamping block chute, the first clamping block group comprises two clamping blocks arranged oppositely along the stacked cups to be separated, and when the cup separation assembly is working, the first clamping block group slides in the first clamping block chute; the first clamping block chute is connected to the pressing cylinder through a pressing transmission column, and can make reciprocating motion in the vertical direction under the drive of the pressing cylinder;

[0013] The cup separation assembly also includes a second clamping block slide groove, and a second clamping block group arranged in the second clamping block slide groove, the second clamping block group includes two clamping blocks arranged opposite to each other along the stacked cups to be separated, and when the cup separation assembly is working, the second clamping block group slides in the second clamping block slide groove; the second clamping block slide groove is connected to the push-pull cylinder through the push-pull cylinder connecting block, and can perform reciprocating motion in the horizontal direction under the drive of the push-pull cylinder.

[0014] The cup-separating assembly in the present invention adopts a structure of two connected clamping blocks and clamping block slideways, and the clamping blocks are all limited in the clamping block slideways and reciprocate under the drive of their respective power mechanisms. A pair of clamping blocks (i.e., clamping block groups) are arranged on both sides of the cup body, and the two clamping blocks are symmetrically positioned and move in a mirror image, which is completely different from the fixed-size fork structure in the prior art. In the present invention, the cup-separating assembly can be adapted to stacked cups of different sizes by simply adjusting the movement trajectory of the clamping blocks.

[0015] Preferably, the non-slip surfaces of the two clamping blocks of the second clamping block group are provided with protrusions, and the non-slip surfaces of the two clamping blocks of the first clamping block group are provided with grooves that are compatible with the shape and position of the protrusions. The first clamping block group and the second clamping block group are buckled in the initial position through the protrusion-groove structure.

[0016] In the cup separation structure, the first clamp block group directly removes the cup body at the bottom of the stacked cups, making it separate from the stacked cups, completing the cup separation action, and the second clamp block group is used to clamp the other stacked cups on the separated cup body to prevent other cup bodies from being pulled. The two groups of clamp blocks have different functions, ensuring that only one cup body is removed each time the cup is separated.

[0017] Preferably, the lower part of the first clamping block slide groove is fixedly connected to the upper slider group, the circumferential side of the limiting cylinder is provided with a matching lower slider group at a position relative to the upper slider group, and the lower slider of the lower slider group and the corresponding upper slider of the upper slider group are provided with matching parallel movable sliding surfaces. The upper slider group and the lower slider group are provided to limit the horizontal movement of the first clamping block group.

[0018] Preferably, a spring assembly is provided on the side of the upper slider, and the spring assembly includes an upper slider fixing block and a spring, one end of the upper slider fixing block is fixedly connected to the first clamping block slot in the vertical direction, and the other end is gap-connected to the upper slider in the horizontal direction, and a spring is sleeved between the upper slider and the upper slider fixing block. On the one hand, the spring structure is used to limit the horizontal movement of the first clamping block group, ensuring the activity trajectory of the first clamping block group after it is separated from the second clamping block group (the horizontal movement has a limited distance, and it can be reset after moving upward). On the other hand, the function of the first clamping block group is to buckle off the cup body at the bottom. When the cup body is buckled off, the force on the first clamping block group will change significantly. The provision of a spring structure can, to a certain extent, mitigate the bounce and impact of the force change on the first clamping block group.

[0019] Preferably, the stacked cup is an industrial plastic charging cup with a thickness greater than or equal to 1 mm, and the number of stacked cups fed is not less than 3. The material cup suitable for the industrial stacking cup dispensing machine in the utility model is preferably an industrial plastic material cup with a certain thickness and strength.

[0020] In order to more effectively separate cups, the shape of the cup ends of the clamping block components needs to be optimized so that the clamping block component cup ends can fully apply the buckling force and clamping force to the stacked cups. Preferably, the end of the first clamping block of the first clamping block group for separating cups is in the shape of an inverted inclined step, including a contoured portion that is contoured to the cup wall of the bottom cup of the stacked cups and a buckling portion buckled at the top of the cup edge of the bottom cup;

[0021] The end of the second clamping block of the second clamping block group for dividing cups is in the shape of an inverted inclined step, and the inverted inclined step-shaped structure is similar to the shape of the outer cup wall of the second to last and third cup bodies stacked at the bottom.

[0022] Preferably, the limiting structure of the clamp block-clamp block slideway structure used in the present invention is a limiting structure that is disassembled and assembled using a fixed block: a fixedly connected clamp block limiting block group is provided on the first clamp block slideway, and the clamp block limiting block group clamps the position of the first clamp block group in the vertical direction so that it can only reciprocate horizontally along the slideway in the first clamp block slideway;

[0023] A fixedly connected clamp block limit block group is provided on the second clamp block slide slot, and the clamp block limit block group clamps the position of the second clamp block group in the vertical direction so that it can only reciprocate horizontally along the slide slot in the second clamp block slide slot.

[0024] The clamping block-clamping block slideway structure of the utility model is not only convenient for installation, but also can make each clamping block and the limit block into a standard product, which is beneficial to the industrialized batch production of the cup dividing machine.

[0025] The industrial cup stacking and separating machine of the utility model can be used as a component of a casting quantitative feeding device to realize full automation of casting quantitative feeding.

[0026] The automatic cup separation method using the cup separation machine of the utility model comprises the following steps:

[0027] S1, push a stack of at least 3 cups into the cup drop channel for feeding, and the stacked cups are fixed at the initial position under the limiting action of the limiting cylinder and the bottom limiting slide;

[0028] S2, turn on the push-pull cylinder to drive the second clamping block group to move inward in the horizontal direction, so as to press the side of the cup body between the bottom of the cup drop channel and the top of the limiting cylinder. The movement state of the second clamping block group is transmitted to the first clamping block group by the convex column-groove structure, so as to drive the first clamping block group to press the side of the cup body at the same time;

[0029] The positions at this time are: the first clamping block group is clamped on the cup body at the bottom of the stacked cups, and the buckle and pull part of the first clamping block is located at the upper end of the cup edge of the bottom cup body; the second clamping block group is clamped on the second to third cup bodies from the bottom of the stacked cups;

[0030] S3, turning on the downward pressure cylinder to drive the first clamping block group to move downward in the vertical direction until the buckling structure of the boss-groove structure is disengaged, and then the first clamping block group is disengaged from the second clamping block group; during the downward movement of the first clamping block group, the buckling part of the first clamping block group buckles the cup edge of the cup body at the bottom of the stacked cup and moves downward;

[0031] At the same time, the limit cylinder is started to drive the limit slide to move to the side, so that the cup body at the bottom of the stacked cups falls into the cup dropping clamp;

[0032] S4, start the downward pressure cylinder again to drive the first clamping block group to move upward in the vertical direction. Due to the locking of the spring structure and the relative sliding of the upper slider and the lower slider, the first clamping block group is re-engaged with the second clamping block group;

[0033] The push-pull cylinder is started again to drive the two clamping block groups to move outward in the horizontal direction, thereby driving the first clamping block group and the second clamping block group to return to their initial positions.

[0034] The industrial cup stacking and separating machine provided in the utility model realizes effective separation of the stacked cups in a compressed state by utilizing the design of the clamping block group according to the characteristics of the industrial material cups, realizes full automation of the cup separation process in industrial production, and makes full automation of the quantitative feeding process possible.

[0035] The industrial cup stacking and separating machine of the utility model also has wide applicability, and can be used in conjunction with the cup separating machine of the utility model regardless of the quantity and method of feeding the stacked cups (automatic feeding or manual feeding).

[0036] Furthermore, the cup separating machine in the utility model can effectively separate the stacked cups without worrying about the problem of difficulty in separating the cups. Therefore, during the turnover of the material cups, the operator can press the stacked cups as tightly as possible to make as many material cups as possible turn over at one time, which not only directly improves the efficiency of the cup separation process, but also indirectly reduces the number of turnover times of the material cups, greatly improving the efficiency of the casting feeding process.

[0047] In order to make the purpose, technical scheme and technical effect of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model is clearly and completely described. The embodiments described below are part of the embodiments of the utility model, not all of the embodiments. In combination with the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. If the specific conditions are not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer; the reagents or instruments used without indicating the manufacturer are all conventional products that can be purchased commercially.

[0048] In the description of the present invention, "at least one" means one or more, and "plurality" means two or more. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c", can all represent: a, b, c, ab (i.e. a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0049] In addition, unless the context clearly uses otherwise, the expression of the singular form of a word should be understood to include the plural form of the word. The term "includes" or "having" is intended to specify the existence of a feature, quantity, step, operation, element, part or combination thereof, but is not used to exclude the existence or possible addition of one or more other features, quantities, steps, operations, elements, parts or combinations thereof.

[0050] The utility model provides a fully automatic industrial cup stacking and separating machine, as shown in the attached Figures 1 to 7 shown.

[0051] It should be noted that in the description of the attached drawings of the present invention, some component names are followed by (left) or (right). The above (left) or (right) is only used to distinguish the components that appear in groups in the structure of the embodiment of the present invention. (Left) or (right) is only used to better understand the relative positions of the components in the embodiment of the present invention by comparing with the drawings, rather than limiting the absolute positions of the components. Similarly, the "vertical direction" and "horizontal direction" mentioned in the present invention are also only used to illustrate the relative directions of the movement of the components, rather than to absolutely limit the movement directions of the components.

[0052] Specifically, the industrial cup stacking and cup separating machine in the embodiment of the utility model includes three major components: a feeding assembly, a cup separating assembly, and a cup dropping and clamping assembly. The feeding assembly includes a cup dropping channel 101 for feeding stacked cups, a limiting cylinder 126, a limiting slide 113, and a limiting slide cylinder 112 connected to the limiting slide. The limiting slide 113 is connected to the limiting slide cylinder 112 through a slide connecting block 117, and the slide assembly is fixed to the equipment frame through a slide cylinder fixing block 114. The limiting slide cylinder 112 is the power mechanism of the limiting slide 113, which enables it to reciprocate in the horizontal direction. The limiting slide cylinder 112 is provided with a slide rail 129 and a slide connecting block 130 connected in sequence, which are used to control the movement trajectory of the limiting slide 113.

[0053] The limiting cylinder 126 is a hollow structure, and its cavity is arranged below the cup dropping channel 101. The limiting slide 113 is arranged below the limiting cylinder 126. The inner diameter of the cup dropping channel 101 and the limiting cylinder 126 is adapted to the diameter of the stacked cups. Preferably, the inner diameter of the cup dropping channel 101 and the limiting cylinder 126 is slightly larger than the diameter of the stacked cups. The stacked cups are in a state of unobstructed self-rotation but unable to move in the horizontal direction. The stacked cups enter the industrial cup stacking and separating machine from the cup dropping channel 101, and are restricted by the limiting cylinder 126 and the limiting slide 113 and fixed at the initial position (such as the attached Figure 2 The stacked cup position shown in FIG. 1 ). At least three stacked cup bodies at the bottom of the stacked cup are exposed in the interval between the bottom of the cup drop channel 101 and the top of the limiting cylinder 126, and the interval is convenient for cup separation. The cup separation assembly is arranged on the peripheral side of the feeding assembly, and the limiting slide 113 is pulled out from the bottom of the stacked cup under the drive of the limiting slide cylinder 112, and then the cup separation assembly separates the outermost cup body (the first cup body 115) of the stacked cup that falls into the feeding assembly from the other cup bodies.

[0054] The cup dropping clamping assembly includes a cup dropping clamping claw 137 and a clamping mechanism cylinder 116 connected thereto. The cup dropping clamping claw 137 is arranged below the limiting slide 113. When the outermost cup body 115 of the stacked cups is separated from the other cup bodies, the separated cup body 115 falls into the cup dropping clamping claw 137 under the action of gravity and is sent to the subsequent workstation under the drive of the clamping mechanism cylinder 116.

[0055] By the attached Figure 1 It can be seen that the cup dropping channel preferably includes a connected U-shaped channel and a hollow cylindrical channel. The cup inlet end of the cup dropping channel is set as an open U-shaped channel, which is convenient for inserting the stacked cups into the channel, and the hollow cylindrical channel immediately following ensures that the stacked cups fall into the initial position.

[0056] The following is combined with Figure 1 ~Attached Figure 5The cup separation structure is described in more detail. The cup separation assembly includes a first clamping block slot 121, and a first clamping block group arranged in the first clamping block slot 121. The first clamping block group includes two clamping blocks arranged relatively along the stacked cups to be separated, namely, a first clamping block (left) 119 and a first clamping block (right) 120. When the cup separation assembly is working, the first clamping block group slides in the first clamping block slot 121, and the first clamping block slot 121 is connected to the pressing cylinder through the pressing transmission column: the pressing transmission column (left) 133 is connected to the pressing cylinder (left) 102 through the pressing linkage plate (left) 132, and the pressing transmission column (right) 135 is connected to the pressing cylinder (right) 103 through the pressing linkage plate (right) 134. The first clamping block slot 121 can make reciprocating motion in the vertical direction driven by the pressing cylinder. The pressing cylinder (left) 102 and the pressing cylinder (right) 103 are respectively mounted on the upper fixing plate 118 through the pressing cylinder fixing seat (left) 104 and the pressing cylinder fixing seat (right) 105. The upper fixing plate 118 and the base 131 are stable supports in the frame structure of the cup dispensing machine of this embodiment. In the cup dispensing machine of this embodiment, the upper fixing plate 118 also serves as a slide groove of the second clamping block.

[0057] The cup separation assembly also includes a second clamping block chute 118, and a second clamping block group arranged in the second clamping block chute 118, and the second clamping block group includes two clamping blocks arranged opposite to each other along the stacked cups to be separated, namely, a second clamping block (left) 108 and a second clamping block (right) 109. When the cup separation assembly is working, the second clamping block group slides in the second clamping block chute 118, and the second clamping block chute 118 is connected to the push-pull cylinder through the push-pull cylinder connecting block: the push-pull cylinder connecting block (left) 138 is connected to the push-pull cylinder (left) 106, and the push-pull cylinder connecting block (right) 139 is connected to the push-pull cylinder (right) 107, and the second clamping block group can perform horizontal reciprocating motion driven by the push-pull cylinder.

[0058] As attached Figure 3 The non-slip surfaces of the two clamping blocks of the second clamping block group are provided with a boss 140, and the non-slip surfaces of the two clamping blocks of the first clamping block group are provided with a groove whose shape and position are adapted to the boss 140. The first clamping block group and the second clamping block group are buckled in the initial position through the boss-groove structure.

[0059] The lower part of the first clamping block slot 121 is fixedly connected to the upper slider group, and the side of the limit cylinder 126 is provided with a matching lower slider group at the relative position of the upper slider group. As shown in the attached figure, the lower slider 123 of the lower slider group and the upper slider 122 of the corresponding upper slider group are provided with matching parallel movable sliding surfaces. Figure 3 As shown, the lower slider (right) 123 is connected to both sides of the limiting cylinder 126 through the lower slider fixing block 125.

[0060] The upper slider 122 is also provided with a spring assembly on its side, the spring assembly comprising an upper slider fixing block and a spring. Figure 3The upper slider fixing block (left) 110 and the spring 124 are shown in FIG. One end of the upper slider fixing block (left) 110 is fixedly connected to the first clamping block sliding groove 121 in the vertical direction, and the other end is gap-connected with the upper slider (left) 122 in the horizontal direction. The spring 124 is sleeved between the upper slider (left) 122 and the upper slider fixing block (left) 110. The upper slider fixing block (right) 111 has the same structure as the left side, which is not repeated here.

[0061] Furthermore, in order to better complete the action of dividing the cups, as shown in the attached Figure 4 The end of the first clamping block (left) 119 of the first clamping block group for separating cups is in the shape of an inverted inclined step, including a profiling portion that is shaped like the cup wall of the bottom cup body of the stacked cups and a buckling portion that is buckled on the top of the cup edge of the bottom cup body. The end of the second clamping block (left) 108 of the second clamping block group for separating cups is in the shape of an inverted inclined step, and the inverted inclined platform-like structure is similar to the shape of the outer cup wall of the second to last and third cup bodies (second cup body 127, third cup body 128) stacked at the bottom, so as to better separate the cup body that does not need to be separated from the first cup body 115.

[0062] Attached Figure 6 This is an exploded view of the clamp block-clamp block slide structure. Figure 7 The schematic diagram of the clamp block-slideway structure connection is shown in the figure. Figure 6 , 7 To further explain the clamp block-slideway structure, the first clamp block slideway 121 and the second clamp block slideway 118 are both provided with a clamp block limit block group 136 that is fixedly connected, and the clamp block limit block group 136 clamps the first clamp block group and the second clamp block group in the vertical direction, so that the clamp block can only reciprocate horizontally along the slideway in the clamp block slideway.

[0063] As attached Figure 7 In the connection structure shown, the clamp block 22 is installed in the clamp block slide groove 21, and the clamp block 22 is limited in the vertical direction by the clamp block limit block (left) 23 and the clamp block limit block (right) 24, and the limit block is fixed to the clamp block slide groove by the fixing screw (left) 25 and the fixing screw (26), so that the clamp block can only reciprocate horizontally along the slide groove in the clamp block slide groove.

[0064] The industrial cup stacking and separating machine of the utility model is suitable for using industrial plastic charging cups with a thickness greater than or equal to 1 mm, and the number of stacked cups fed is not less than 3.

[0065] The method of using the industrial cup stacking and separating machine in this embodiment is as follows:

[0066] S1, push a stack of at least 3 cups into the cup drop channel 101 for feeding (such as the attached Figure 2 ), the stacked cups are fixed at the initial position under the limiting action of the limiting cylinder 126 and the bottom limiting slide 113. The "initial position" is as follows: Figure 2 The middle part shows the position where the stacked cups fall into the cup dropping channel and are fixed on the limiting slide 113 , rather than the position of the first cup body 115 .

[0067] S2, open the push-pull cylinders 106, 107, drive the second clamp block group 108, 109 to move inward in the horizontal direction, so as to press the side of the cup body between the bottom of the cup drop channel and the top of the limiting cylinder, and the movement state of the second clamp block group is transmitted to the first clamp block group 119, 120 by the boss-groove structure, so as to drive the first clamp block group to press the side of the cup body at the same time.

[0068] From the attached Figure 4 You can see it more clearly in Figure 4 for Figure 2 Schematic diagram of the structure before the outermost cup body 115 of the middle stacked cup is buckled and separated. At this time, the position is: the first clamping block group is clamped on both sides of the cup body 115 at the bottom of the stacked cup, and the buckling part of the first clamping block 119 is located at the upper end of the cup edge of the bottom cup body 115 (the buckling part of the first clamping block 120 is at the upper end of the cup edge on the other side of the cup body 115, this structure is symmetrical with the clamping block 119 and is not Figure 4 ), the second clamp block group 108, 109 (not shown in Figure 4 The middle logo) is clipped on the second to third cup bodies from the bottom of the stacked cups.

[0069] S3, open the downward pressure cylinders 102 and 103, drive the first clamping block group to move downward in the vertical direction until the buckling structure of the boss-groove structure is disengaged, and then the first clamping block group is disengaged from the second clamping block group. During the downward movement of the first clamping block group, the buckling part of the first clamping block group buckles the cup edge of the bottom of the stacked cup and moves downward. Figure 5 The connection method and working method of the downward pressure cylinder and the clamping block group are clearly given.

[0070] At the same time, the limiting slide cylinder 112 is started, and the limiting slide 113 is driven to move sideways through the slide rail 129 and the slide connecting block 130 , so that the cup body 115 at the bottom of the stacked cups falls into the cup dropping clamp 137 .

[0071] S4, start the downward pressure cylinders 102 and 103 again, driving the first clamping block group to move upward in the vertical direction. Due to the locking of the spring structure 124 and the relative sliding of the upper slider 122 and the lower slider 123, the first clamping block group is re-engaged with the second clamping block group.

[0072] The push-pull cylinders 106 and 107 are started again to drive the two clamping block groups to move outward in the horizontal direction, thereby driving the first clamping block group and the second clamping block group to return to their initial positions.

[0073] It can be seen from the above embodiments that the industrial cup stacking and separating machine provided in the utility model realizes effective separation of the stacked cups in a compacted state by utilizing the design of the clamping block group according to the characteristics of the industrial material cups, and realizes full automation of the cup separation process in industrial production, making full automation of the quantitative feeding process possible. The cup separating machine in the utility model can effectively separate the stacked cups without worrying about the problem of difficulty in cup separation. Therefore, during the turnover of the material cups, the operator can compact the stacked cups as much as possible to make as many material cups as possible turn over at one time, which not only directly improves the efficiency of the cup separation process, but also indirectly reduces the number of turnovers of the material cups, greatly improving the efficiency of the casting feeding process.

[0074] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
