(overview)
Hereinafter, some embodiments included in the frozen object striking device will be described based on the drawings. In this embodiment, as an example of the frozen butter striking device, a frozen butter striking device that destroys frozen butter by striking a package containing frozen butter with a hammer will be described. In the drawings for explaining the present embodiment, the same parts are generally denoted by the same reference numerals, and repeated explanations thereof will be omitted.

(Configuration of frozen butter striking device)
1, 2 and 3, a frozen butter striking device 10 is shown. The frozen butter striking device 10 includes a support base 11, a plurality of columns 12, a receiving plate 13, a butter hammer 14, a plurality of pipe guides 15, a weight 16, a rodless cylinder 17, and a rodless cylinder bracket ( (hereinafter abbreviated as "bracket") 18, a bracket arm 19, a weight support mechanism 20, and a cover 21.

The support stand 11 is an element that supports other elements and mechanisms that constitute the frozen butter striking device 10, and also supports the package 23 containing the frozen butter 22. Frozen butter 22 is butter that has been frozen to increase its hardness. The support stand 11 is placed at a use location 25 via a plurality of level adjuster bolts 24. The plurality of level adjuster bolts 24 are provided to support the support stand 11 and to adjust the height of the support stand 11 with respect to the usage location 25 in the vertical direction. Vertical direction means the direction of action of gravity. The support stand 11 is made of, for example, a metal plate, and the support stand 11 is kept substantially horizontal by a plurality of level adjuster bolts 24. As shown in FIG. 3, when the support base 11 is viewed in plan from directly above in the vertical direction, the outer peripheral shape of the support base 11 is, for example, a substantially quadrangular shape.

As an example, four pillars 12 are provided. Each of the plurality of pillars 12 is made of a square metal pipe. The plurality of pillars 12 are fixed to the upper surface of the support base 11, respectively, in a vertically erected state. The four pillars 12 are arranged at different positions on the upper surface of the support base 11. Specifically, when the support base 11 is viewed from above, the pillars 12 are arranged at positions corresponding to four corners of a quadrilateral, for example, a rectangle.

The receiving plate 13 is an element that supports the butter hammer 14, the plurality of pipe guides 15, etc., and the receiving plate 13 is fixed to the four pillars 12. The receiving plate 13 is made of, for example, a metal plate, and is held substantially horizontally by the four pillars 12. As shown in FIG. 5, a plate 26 is fixed to the upper surface of the receiving plate 13. Further, a hole 27 is provided that vertically passes through the plate 26 and the receiving plate 13.

The butter hammer 14 is an element that transmits the impact force received from the weight 16 to the package 23 and the frozen butter 22. Specifically, the butter hammer 14 is an element that strikes the package 23 containing the frozen butter 22. The butter hammer 14 is made of metal, for example, and is supported by the receiving plate 13 via a hammer support mechanism 28. The butter hammer 14 has a protrusion 29 that projects downward in the vertical direction while being supported by the hammer support mechanism 28 .

The butter hammer 14 is supported by a hammer support mechanism 28 so that it can move within a predetermined range in the vertical direction with respect to the receiving plate 13. The hammer support mechanism 28 includes a plurality of bolts, a nut attached to each bolt, and a tension coil spring attached to each bolt. The compression coil spring can be expanded and contracted in the vertical direction. The predetermined range in which the butter hammer 14 can move in the vertical direction is determined depending on the mounting position of the nut relative to the bolt in the vertical direction, the spring constant of the tension coil spring, and the like. Further, a metal receiving ring 30 is placed on the plate 26 of the receiving plate 13.

A plurality of pipe guides 15, specifically three pipe guides 15, are provided to protrude from the upper surface of the plate 26 in the vertical direction. The three pipe guides 15 are elements that prevent the weight 16 from moving in a direction intersecting the vertical direction. The three pipe guides 15 are made of metal. As shown in FIG. 3, when the receiving plate 13 is viewed from above, the three pipe guides 15 are arranged at equal intervals on the same circumference centered on the reference position A1.

The weight 16 is an element for applying a striking force to the butter hammer 14, and is made of metal, for example. The weight 16 has a cylindrical shape, and an engagement groove 31 is provided in the upper part of the weight 16. The engagement groove 31 is provided in an annular shape around the entire circumference of the weight 16. Further, a protrusion 32 that comes into contact with the butter hammer 14 is provided at the lower end of the weight 16. The weight 16 is arranged above the butter hammer 14 in the vertical direction, as shown in FIGS. 4 and 5.

The weight 16 can move along the vertical direction, that is, can move up and down. The weight 16 can be lowered, that is, dropped by gravity, and can be raised and lowered along the virtual line B1 shown in FIG. 4 while being supported by the rodless cylinder 17. The virtual line B1 is a straight line extending in the vertical direction, and the virtual line B1 passes through the reference position A1 shown in FIG. 3. As shown in FIG. 3, when the receiving plate 13 is viewed from above, the engagement groove 31 and the protrusion 32 are arranged around the reference position A1. When the weight 16 is raised or lowered, the protrusion 32 can move into and out of the receiving ring 30 and the hole 27. When the weight 16 descends and the protrusion 32 enters the hole 27, the tip of the protrusion 32 reaches below the receiving plate 13 in the vertical direction and strikes the butter hammer 14.

The weight 16 is arranged between the three pipe guides 15 in the space above the receiving plate 13. When the weight 16 comes into contact with the three pipe guides 15, movement of the weight 16 in a direction different from the vertical direction is restricted. As shown in FIG. 3, when the receiving plate 13 is viewed from directly above, the outer peripheral surface of the weight 16 has a circular shape centered on the reference position A1, and the weight 16 is arranged centered on the reference position A1. There is.

The rodless cylinder 17 is provided on the support base 11. The rodless cylinder 17 has the function of raising and lowering the weight 16. As shown in FIG. 3, the rodless cylinder 17 includes a linear guide 33, a slider 34, a cylinder tube, a first air chamber 80, a second air chamber 81, a piston 82, and the like. The linear guide 33 is a rail provided along the vertical direction. The slider 34 is attached to the linear guide 33. A first air chamber 80, a second air chamber 81, and a piston are provided in the cylinder tube, and the first air chamber 80 and the second air chamber 81 are partitioned by the piston 82. Compressed air is supplied to either the first air chamber 80 or the second air chamber 81, and compressed air is discharged from the other. The piston 82 is connected to the slider 34, and the slider 34 and the piston 82 are moved in the vertical direction along the linear guide 33. When the air pressure in the first air chamber 80 is increased, the piston 82 and the slider 34 are raised, and when the air pressure in the second air chamber 81 is increased, the piston 82 and the slider 34 are lowered. In this way, the slider 34 is reciprocated and stopped between the top dead center and the bottom dead center. In the vertical direction, the top dead center is higher than the bottom dead center.

Further, a rodless cylinder bracket (hereinafter abbreviated as "bracket") 18 is fixed to the slider 34. Furthermore, two bracket arms 19 are fixed to the bracket 18. In a plan view of the rodless cylinder 17, the two bracket arms 19 are arranged in parallel, and the two bracket arms 19 can support the weight 16 via the receiving ring 30. The rodless cylinder 17 and the two bracket arms 19 are operated in the vertical direction together with the slider 34. Therefore, when the slider 34 rises along the linear guide 33 with the two bracket arms 19 supporting the weight 16, the weight 16 also rises. When the slider 34 descends along the linear guide 33 with the two bracket arms 19 supporting the weight 16, the weight 16 is also descended.

The weight support mechanism 20 is provided to support the weight 16 lifted by the rodless cylinder 17 at the top dead center in the vertical direction. When the weight 16 is supported at the top dead center, the lower end of the weight 16 is stopped at a position higher than the receiving plate 13 by a predetermined amount, for example, 1.5 m or more. As shown in FIGS. 3 and 6, the weight support mechanism 20 includes an upper plate 35 and a lower plate 36 fixed to the pipe guide 15, a cylinder bracket 37 fixed to the lower plate 36, and a cylinder bracket 37 provided on the cylinder bracket 37. It has an air cylinder 38, a drive ring 39 interposed between an upper plate 35 and a lower plate 36, and an insertion/extraction lever 40 connected to the drive ring 39.

The upper plate 35 is arranged above the lower plate 36 in the vertical direction. As shown in FIG. 3, when the receiving plate 13 is viewed from above, the upper plate 35 and the lower plate 36 are formed in an annular shape centered on the reference position A1. Lever guide pins 69 and 70 are fixed to the upper plate 35 and the lower plate 36. Drive ring 39 is arranged between upper plate 35 and lower plate 36. As shown in FIG. 3, when the receiving plate 13 is viewed from above, the drive ring 39 is arranged in an annular shape centered on the reference position A1. The drive ring 39 is movable with respect to the upper plate 35 and the lower plate 36 within a predetermined angular range about the reference position A1. The insertion/extraction lever 40 is attached to the drive ring 39 so as to be operable about a support shaft 41 . A plurality of, for example, two, insertion/extraction levers 40 are provided, and the support shafts 41 are arranged on the same circumference centered on the reference position A1 in a plan view of the receiving plate 13.

The air cylinder 38 has a plunger 42 that can be reciprocated, and the plunger 42 is connected to a drive ring 39 . The plunger 42 is pushed by a compression spring (not shown), and the drive ring 39 is urged counterclockwise in FIG. 3. When the compressed air is discharged from the air cylinder 38, the plunger 42 is stopped at the forward position pushed by the compression spring. Further, the insertion/extraction lever 40 comes into contact with the lever guide pin 69 and is stopped. Therefore, when the weight 16 is located at the top dead center, the tip of the insertion/extraction lever 40 enters the engagement groove 31 of the weight 16 and stops. That is, the insertion/extraction lever 40 is engaged with the weight 16, and the weight 16 is held at the top dead center.

On the other hand, when compressed air is supplied to the air cylinder 38 while the insertion/extraction lever 40 holds the weight 16 at the top dead center, the plunger 42 retreats from the forward position against the force of the compression spring. The drive ring 39 is rotated clockwise within a predetermined angle range. When the drive ring 39 is rotated clockwise, the insertion/extraction lever 40 contacts the lever guide pin 70, operates clockwise around the support shaft 41, and stops. Therefore, the tip of the insertion/extraction lever 40 exits from the engagement groove 31 of the weight 16. That is, the insertion/extraction lever 40 is released from the weight 16, and the weight 16 can descend from the top dead center.

The cover 21 is a structure that covers the space above the receiving plate 13. The cover 21 is attached to the support column 12, and the operator can open and close the cover 21. In the space covered by the cover 21, three pipe guides 15, a weight support mechanism 20, a weight 16, etc. are arranged. The cover 21 is made of metal, for example, and has a window 43 opened therein. The window 43 is covered with a transparent or translucent member 44. The light-transmitting member 44 includes glass or synthetic resin. The operator can visually observe the inside of the cover 21 from the outside of the cover 21 through the light-transmitting member 44 . An operation panel 45 is provided on the cover 21. The operation panel 45 is provided with various operation buttons operated by the operator, such as a start button 45A, a stop button 45B, an automatic button 45C, a run button 45D, and an end button 45E. When the operation panel 45 is operated, the supply state of compressed air to the rodless cylinder 17 and the supply state of compressed air to the weight support mechanism 20 are controlled.

(Various detection mechanisms)
A metal stay 46 is provided upright on the upper surface of the receiving plate 13. A bracket 47 is attached to the stay 46, and a mechanical valve 48 and a valve switch fitting 49 are attached to the bracket 47. The valve switch fitting 49 is provided to be operable, and the state of the valve switch fitting 49 is switched between on when it is in contact with the weight 16 and off when it is separated from the weight 16. Note that the valve switch fitting 49 can also be turned on and off manually by the operator.

Further, bracket contact switches 50 and 83 shown in FIG. 7A are provided. When the bracket contact switches 50 and 83 are brought into contact with or separated from the bracket 18, their operating states are switched depending on the position of the bracket 18 in the vertical direction. The bracket contact switch 50 is contacted when the bracket 18 is located at the bottom dead center, and is separated when the bracket 18 is located above the bottom dead center. The bracket contact switch 83 is brought into contact when the bracket 18 is located at the top dead center, and is separated when the bracket 18 is located below the top dead center. Furthermore, speed controllers 51 and 84 shown in FIG. 7A are provided. The speed controller 84 supplies air to the first air chamber 80 of the rodless cylinder 17 and discharges air from the first air chamber 80. Further, the speed controller 84 adjusts the flow rate of compressed air discharged from the first air chamber 80 to be less than the flow rate of compressed air supplied to the second air chamber 81. The speed controller 51 supplies air to the second air chamber 81 of the rodless cylinder 17 and discharges air from the second air chamber 81. Further, the speed controller 51 adjusts the flow rate of compressed air discharged from the second air chamber 81 to be less than the flow rate of compressed air supplied to the first air chamber 80. Since the speed controller 51 adjusts the flow rate of compressed air discharged from the second air chamber 81, the speed at which the bracket 18 rises can be adjusted. Since the speed controller 84 adjusts the flow rate of compressed air discharged from the first air chamber 80, the speed at which the bracket 18 descends can be adjusted.

A package detection switch 52 shown in FIG. 5 is provided. The package detection switch 52 is provided, for example, between the support stand 11 and the butter hammer 14. The package detection switch 52 is activated when it comes into contact with the package 23 placed on the support stand 11 . If the package 23 is not on the support base 11, the package detection switch 52 will not operate.

(circuit diagram)
FIG. 7A is a circuit diagram schematically showing a compressed air supply system in the frozen butter battering device 10. An air compressor 56, which is an example of an air machine that sucks in air and discharges compressed air, is provided. A passage 53 is connected to a discharge port of the air compressor 56. A passage 90 is connected to the passage 53, and the passage 90 is connected to a mechanical valve 91. The state of the mechanical valve 91 is switched depending on the operating state of the bracket contact switch 50, that is, the position of the bracket 18 in the vertical direction. Mechanical valve 91 is connected to passage 92 . Mechanical valve 91 has an input port 93, an output port 94, a drain port 95, a plunger, and a compression spring. The state of the mechanical valve 91 is switched by operating a plunger.

As shown in FIG. 7D, when the bracket 18 is located at the bottom dead center, the mechanical valve 91 connects the input port 93 and the output port 94 and closes the drain port 95. Therefore, compressed air discharged from the air compressor 56 is supplied to the input port 93 through the passages 53 and 90, and is also supplied to the passage 92 from the output port 94. The mechanical valve 91 connects the output port 94 and the drain port 95 and closes the input port 93 when the bracket 18 is positioned above the bottom dead center as shown in FIG. 7G. Therefore, the compressed air in the passage 92 is discharged from the drain port 95.

Further, as shown in FIG. 7A, a mechanical valve 100 is provided whose state is switched depending on the operating state of the bracket contact switch 83, that is, the position of the bracket 18 in the vertical direction. Mechanical valve 100 is connected to passages 101 and 102. Passage 101 is connected to passage 53. Mechanical valve 100 has an input port 103, an output port 105, a drain port 104, a plunger, and a compression spring. Input port 103 is connected to passage 101 and output port 105 is connected to passage 102. The state of the mechanical valve 100 is switched by operating a plunger.

When the bracket 18 is located at the top dead center as shown in FIG. 7C, the mechanical valve 100 connects the input port 103 and the output port 105 and closes the drain port 104. Therefore, the compressed air in the passage 101 is supplied to the passage 102 from the output port 105. When the bracket 18 is located below the top dead center as shown in FIG. 7B, the mechanical valve 100 connects the output port 105 and the drain port 104 and closes the input port 103. Therefore, the compressed air in the passage 102 is discharged from the drain port 104.

As shown in FIGS. 4 and 5, the mechanical valve 48 is connected to a valve switch fitting 49, and the state of the mechanical valve 48 is switched depending on the position of the weight 16 in the vertical direction. As shown in FIG. 7A, mechanical valve 48 is connected to passage 92 and passage 96. The mechanical valve 48 has an input port 97, an output port 98, a drain port 99, a plunger, a compression spring, and the like. Input port 97 is connected to passage 92 and output port 98 is connected to passage 96. The state of the mechanical valve 48 is switched by operating a plunger. As shown in FIG. 7F, when the weight 16 is located at the bottom dead center, the mechanical valve 48 connects the input port 97 and the output port 98, and closes the drain port 99. Therefore, the compressed air supplied to the passage 92 is supplied to the passage 96 from the output port 98. As shown in FIG. 7B, when the weight 16 is located above the bottom dead center, the mechanical valve 48 connects the output port 98 and the drain port 99 and closes the input port 97. Therefore, the compressed air in the passage 96 is discharged from the drain port 99.

Furthermore, as shown in FIG. 7A, a passage 106 is connected to the passage 53. An air operated valve 60 connected to the passages 96, 102, 106, 113, and 114 is provided. The air operated valve 60 has a function of switching and supplying compressed air discharged from the air compressor 56 to the first air chamber 80 and the second air chamber 81. The air operated valve 60 has an input port 107, output ports 108 and 109, a drain port 110, operating pressure (signal pressure) ports 111 and 112, and a plunger. Input port 107 is connected to passage 106 and output port 108 is connected to passage 113. The passage 113 is connected to the first air chamber 80 , and a speed controller 84 is provided in the passage 113 . Output port 109 is connected to passageway 114. The passage 114 is connected to the second air chamber 81, and the speed controller 51 is provided in the passage 114. Operating pressure port 111 is connected to passage 96 and operating pressure port 112 is connected to passage 102.

The operating state of the air operated valve 60 is switched depending on the difference between the pressure of compressed air supplied to the operating pressure port 111 and the pressure of compressed air supplied to the operating pressure port 112. In the air operated valve 60, when the pressure of the operating pressure port 111 and the pressure of the operating pressure port 112 are the same, the plunger does not operate and the state is maintained. In the air operated valve 60, when the pressure in the operating pressure port 111 exceeds the pressure in the operating pressure port 112, the input port 107 and the output port 108 are connected, and the output port 109 and the drain are connected, as shown in FIG. 7B. Port 110 is connected. Therefore, the compressed air in the passage 106 is supplied to the first air chamber 80 via the output port 108 and the passage 113. Further, the compressed air in the second air chamber 81 is discharged from the drain port 110 via the passage 114. Therefore, the bracket 18 and piston 82 rise.

On the other hand, if the pressure in the operating pressure port 112 exceeds the pressure in the operating pressure port 111, the input port 107 and the output port 109 are connected, and the output port 108 and the drain port are connected, as shown in FIG. 7C. 110 is connected. Therefore, the compressed air in the passage 106 is supplied to the second air chamber 81 via the output port 109 and the passage 114. Further, the compressed air in the first air chamber 80 is discharged from the drain port 110 via the passage 113. Therefore, the bracket 18 and the piston 82 are lowered. Note that the speed at which the bracket 18 and the piston 82 rise and fall are adjusted by the speed controllers 51 and 84, respectively.

Further, a mechanical valve 86 shown in FIG. 7A is provided, the operating state of which changes depending on the operating state of the package detection switch 52 shown in FIG. 5, that is, the presence or absence of the package 23. Mechanical valve 86 is connected to passages 115 and 116. Passage 116 is connected to passage 106. Mechanical valve 48 has an input port 117, an output port 118, and a drain port 119. Input port 117 is connected to passage 116 and output port 118 is connected to passage 115. When the package 23 is on the support base 11, the mechanical valve 86 connects the input port 117 and the output port 118 and closes the drain port 119, as shown in FIG. 7D. Therefore, compressed air discharged from the air compressor 56 is supplied to the passage 115 through the passages 106 and 116 and the output port 118. When the package 23 is not on the support base 11, the mechanical valve 86 connects the output port 118 and the drain port 119 and closes the input port 117, as shown in FIG. 7B. Therefore, the compressed air in the passage 115 is discharged from the drain port 119.

As in FIG. 7A, passageway 115 is connected to push button valve 120. The state of the push button valve 120 is changed by operating a button provided on the operation panel 45. Push button valve 120 has an input port 121, an output port 122, and a drain port 123. Input port 121 is connected to passage 115 and output port 122 is connected to passage 124. When the automatic button 45C on the operation panel 45 is pressed, the push button valve 120 connects the input port 121 and the output port 122 and closes the drain port 123, as shown in FIG. 7E. Therefore, the compressed air in the passage 115 is supplied to the passage 124. If automatic button 45C is not pressed, push button valve 120 connects output port 122 and drain port 123 and closes input port 121 as shown in FIG. 7D. Therefore, the compressed air in the passage 124 is discharged from the drain port 123.

Furthermore, a cover valve 125 is provided as shown in FIG. 7A. The state of the cover valve 125 changes depending on whether the cover switch 126 shown in FIG. 1 is turned on or off. The cover switch 126 is turned on when the cover 21 is closed, and turned off when the cover 21 is opened. Cover valve 125 has an input port 127, an output port 128, and a drain port 129. Input port 127 is connected to passage 124 and output port 128 is connected to passage 130. When the cover switch 126 is turned on, the cover valve 125 connects the input port 127 and the output port 128 and closes the drain port 129, as shown in FIG. 7E. Therefore, the compressed air in passage 124 is supplied to passage 130. When cover switch 126 is turned off, cover valve 125 connects input port 127 and drain port 129 and closes output port 128. Therefore, the compressed air in the passage 124 is discharged from the drain port 129.

Furthermore, as shown in FIG. 7A, an air operated valve 85 is provided to switch between supplying compressed air to the air cylinder 38 and discharging the compressed air. The air operated valve 85 has an input port 140, an output port 141, a drain port 142, operating pressure (signal pressure) ports 143 and 150, and a plunger. Input port 140 is connected to passage 53 and output port 141 is connected to air cylinder 38 via passage 145. Operating pressure port 143 is connected to passageway 130. Operating pressure port 150 is connected to passageway 146. Furthermore, a passage 147 connected to the operating pressure port 143 is provided. A switching valve 148 is provided to connect the passage 102 to either the passage 146 or the passage 147. The state of the switching valve 148 is switched by the operator operating the select switch 149. When the select switch 149 is turned off, the switching valve 148 connects the passage 102 and the passage 146 and blocks the passage 102 and the passage 147. The switching valve 148 connects the passage 102 and the passage 147 and blocks the passage 102 and the passage 146 when the select switch 149 is turned on.

The operating state of the air operated valve 85 is switched depending on the difference between the pressure of compressed air supplied to the operating pressure port 143 and the pressure of compressed air supplied to the operating pressure port 150. In the air operated valve 85, when the pressure in the operating pressure port 143 and the pressure in the operating pressure port 150 are the same, the plunger does not operate and the state is maintained. When the pressure in the operating pressure port 143 exceeds the pressure in the operating pressure port 150, the air operated valve 85 connects the input port 140 and the output port 141 and closes the drain port 142, as shown in FIG. 7E. It will be done. Therefore, the compressed air in the passage 53 is supplied to the air cylinder 38 via the output port 141 and the passage 145. Therefore, the insertion/extraction lever 40 is released from the weight 16.

On the other hand, when the pressure in the operating pressure port 150 exceeds the pressure in the operating pressure port 143, both the input port 140 and the output port 141 are connected to the drain port 142, as shown in FIG. 7D. Therefore, the compressed air in the air cylinder 38 is discharged from the drain port 142 through the passage 145. Therefore, the insertion/extraction lever 40 is engaged with the weight 16.

(Example of operation)
8 and 9 show an example of the operation of the frozen butter striking device 10 in this embodiment, that is, a frozen butter striking method. In this embodiment, it is assumed that the cover 21 is basically closed and is opened only during maintenance or the like.

(initial state)
The initial state of the frozen butter striking device 10 means a state in which the operation panel 45 is not operated, the air compressor 56 is stopped, and the package 23 is not on the support stand 11. Compressed air is not discharged from the air compressor 56. In the initial state of the frozen butter striking device 10, as shown in FIGS. 7A and 8, the bracket 18 is stopped at the bottom dead center, and the weight 16 is stopped at the bottom dead center while being supported by the bracket arm 19. ing. Therefore, the mechanical valve 91 connects the input port 93 and the output port 94, as shown in FIG. 7A. Further, the mechanical valve 48 connects an input port 97 and an output port 98. Furthermore, the mechanical valve 100 closes the input port 103. Further, the air operated valve 85 connects the input port 140 and the output port 141 and closes the drain port 142. Furthermore, the butter hammer 14 is stopped at the initial position.

(1st step)
The operator operates the start button 45A on the operation panel 45 to start the frozen butter striking device 10. Further, the select switch 149 on the operation panel 45 is turned off. Next, when the operator operates (turns on) the automatic button 45C on the operation panel 45, the air compressor 56 is driven to discharge compressed air. Compressed air discharged from the air compressor 56 is supplied to the operating pressure port 111 through passages 53, 92, and 96, as shown in FIG. 7A. Then, the air operated valve 60 connects the input port 107 and the output port 108, and also connects the output port 109 and the drain port 110. Therefore, the compressed air in the passage 106 is supplied to the first air chamber 80 through the passage 113. Therefore, the rodless cylinder 17 is operated and the bracket 18 and weight 16 are raised from the bottom dead center.

When the bracket 18 is raised from the bottom dead center, as shown in FIG. 7B, the output port 94 of the mechanical valve 91 is closed, and the compressed air in the passage 90 is no longer supplied to the passage 92. Furthermore, when the weight 16 is raised from the bottom dead center, the input port 97 of the mechanical valve 48 is closed, and the output port 98 and drain port 99 are connected. However, while the bracket 18 is located below the top dead center, the state of the mechanical valve 100 is not switched and compressed air is not supplied to the passage 102. Therefore, the air operated valve 60 is maintained in a state in which the input port 107 and the output port 108 are connected, and the output port 109 and the drain port 110 are connected. Therefore, the bracket 18 and weight 16 continue to rise.

Further, while the bracket 18 is located below the top dead center, compressed air is not supplied to the operating pressure port 150 of the air operated valve 85, and the state of the air operated valve 85 is not switched. Therefore, compressed air is supplied to the air cylinder 38 via the passages 53, 145, and the plunger 42 moves from the forward position to the backward position and then stops.

Thereafter, as shown in FIGS. 8 and 7C, when the bracket 18 and the weight 16 reach the top dead center, the mechanical valve 100 connects the input port 103 and the output port 105. The compressed air in the passage 101 is then supplied to the operating pressure port 112 through the passage 102. Therefore, the air operated valve 60 connects the input port 107 and the output port 109, and also connects the output port 108 and the drain port 110. Then, the compressed air in the passage 106 is supplied to the second air chamber 81 through the passage 114, and the compressed air in the first air chamber 80 is discharged from the drain port 110 through the passage 113. Therefore, the bracket 18 is lowered from the top dead center to the bottom dead center.

On the other hand, when the bracket 18 reaches the top dead center, a portion of the compressed air supplied to the passage 102 is supplied to the operating pressure port 150 of the air operated valve 85. Then, the state of the air operated valve 85 is switched, the output port 141 and the drain port 142 are connected, and the input port 140 is closed. Therefore, the compressed air in the air cylinder 38 is discharged to the drain port 142 through the passage 145. Therefore, the plunger 42 of the air cylinder 38 moves from the retracted position to the forward position and then stops. That is, the insertion/extraction lever 40 is engaged with the weight 16 located at the top dead center. In this way, the weight 16 is held at top dead center. After the weight 16 is held at the top dead center as described above, the bracket 18 reaches the bottom dead center and stops as shown in FIGS. 8 and 7D.

(Second process)
After the bracket 18 is stopped at the bottom dead center, the operator places the package 23 containing the frozen butter 22 on the support stand 11 and slides the package 23 under the butter hammer 14. and stop. Here, the weight 16 is held at top dead center, and the butter hammer 14 is lifted upward by the tension coil spring of the hammer support mechanism 28. That is, the mass of the weight 16 and the mass of the butter hammer 14 are not added to the package 23. The work of placing the package 23 on the support stand 11 and sliding it can be performed smoothly. Furthermore, when the package is placed on the support stand 11, the package detection switch 52 is activated. Therefore, mechanical valve 86 connects input port 117 and output port 118 and closes drain port 119. The compressed air in the passage 116 is then supplied to the passage 115.

(3rd step)
When the operator operates the operation button 45D of the operation panel 45 in the third step, the push button valve 120 connects the input port 121 and the output port 122 and closes the drain port 123. Therefore, as shown in FIG. 7E, the compressed air in the passage 115 is supplied to the operating pressure port 143 via the passages 124 and 130. Then, the state of the air operated valve 85 is switched, the input port 140 and the output port 141 are connected, and the drain port 142 is blocked. Therefore, the compressed air in the passage 53 is supplied to the air cylinder 38 through the passage 145, and the plunger 42 is operated from the forward position to the retracted position, and the plunger 42 is stopped.

When the plunger 42 moves to the retreat position, the insertion/extraction lever 40 is released from the weight 16, and the weight 16 descends under its own weight, that is, falls naturally, as shown in FIG. The protrusion 29 of the weight 16 enters the hole 27, and the protrusion 29 hits the butter hammer 14, and the weight 16 stops at the bottom dead center as shown in FIG. 7F. Further, the butter hammer 14 moves vertically downward by a predetermined amount, and the butter hammer 14 strikes the package 23 and the frozen butter 22. Specifically, the protrusion 29 bites into the package 23 and the frozen butter 22, and the frozen butter 22 is destroyed. In other words, the frozen butter 22 breaks. Note that when the package 23 is not placed on the receiving plate 13, the package detection switch 52 is not activated, and compressed air is not supplied to the air cylinder 38 even if the operation button 45D is operated. Therefore, the weight 16 is held at the top dead center.

(4th step)
When the weight 16 reaches the bottom dead center, the state of the mechanical valve 48 is switched, and the compressed air in the passage 92 is supplied to the operating pressure port 111 through the passage 96. Therefore, the state of the air operated valve 60 is switched, and compressed air is supplied to the first air chamber 80 and compressed air is discharged from the second air chamber 81, similarly to the first step. Therefore, the bracket 18 and the weight 16 are raised as shown in FIG. 7G in the same manner as in the first step. Note that since the automatic button 45C is operated in the first step, the bracket 18 and the weight 16 are raised in the fourth step without operating the automatic button 45C in the same way as in the first step.

When the bracket 18 rises from the bottom dead center, the state of the mechanical valve 91 is switched and the input port 93 is closed. Furthermore, when the weight 16 rises from the bottom dead center, the state of the mechanical valve 48 is switched and the input port 97 is closed. However, while the bracket 18 is located below the top dead center, the state of the mechanical valve 100 is not switched and compressed air is not supplied to the passage 102. Therefore, the state of the air operated valve 60 is maintained, and the bracket 18 continues to rise.

When the bracket 18 and the weight 16 reach the top dead center, the state of the mechanical valve 100 is switched in the same manner as described above, and compressed air is supplied to the passage 102. Therefore, the state of the air operated valve 85 is switched in the same manner as described above, the insertion/removal lever 40 is engaged with the weight 16, and the weight 16 is held at the top dead center. After the weight 16 is held at the top dead center, the bracket 18 and bracket arm 19 are lowered based on the same principle as described above. Then, as in the second step, when the bracket arm 19 and the bracket 18 reach the bottom dead center, the bracket 18 is stopped at the bottom dead center.

(5th step)
After the bracket 18 is stopped at the bottom dead center, the operator slides the package 23 on the support stand 11 and changes the position of the butter hammer 14 with respect to the package 23 in plan view of the support stand 11. do. Then, by performing the first to fourth steps, the operator hits the package 23 and the frozen butter 22 again with the butter hammer 14, and then places the package 23 containing the frozen butter 22 on the support stand 11. remove from

(Finishing process 1)
An example in which the operator terminates the use of the frozen butter striking device 10 after removing the package 23 from the support stand 11 will be described based on termination steps 1 to 4. The finishing step 1 shown in FIG. 10A is performed in a state where the weight 16 is held at the top dead center and the bracket 18 is stopped at the bottom dead center, similar to the state shown in FIG. 7D. In the finishing step 1, compressed air is discharged from the first air chamber 80, and compressed air is supplied to the second air chamber 81. Therefore, the bracket 18 is stopped at the bottom dead center. Further, compressed air is discharged from the cylinder 38, and the insertion/removal lever 40 is engaged with the weight 16, so that the weight 16 is held at the top dead center. Further, the passage 102 is not supplied with compressed air.

(Ending process 2)
The operator manually turns on the select switch 149 in finishing step 2 shown in FIG. 10B. Then, the switching valve 148 connects the passage 102 and the passage 147 and blocks the passage 102 and the passage 101. Next, the operator manually turns on the valve switch fitting 49. Then, the state of the mechanical valve 48 is switched, the input port 97 and the output port 98 are connected, and compressed air is supplied to the operating pressure port 111 of the air operated valve 60. Therefore, the state of the air operated valve 60 is switched, the input port 107 and the output port 108 are connected, and the output port 109 and the drain port 110 are connected. Therefore, compressed air is supplied to the first air chamber 80, compressed air is discharged from the second air chamber 81, and the bracket 18 is raised.

When the bracket 18 is raised, the state of the mechanical valve 91 is changed, the input port 93 is closed, and the output port 94 and the drain port 95 are connected. Therefore, compressed air is no longer supplied to the operating pressure port 111. However, while the bracket 18 is located below top dead center, no compressed air is supplied to the passage 102. Therefore, the state of the air operated valve 60 is maintained, and the bracket 18 continues to rise.

(Ending process 3)
When the bracket 18 reaches the top dead center as shown in FIGS. 9 and 10C, the state of the mechanical valve 100 is switched, the input port 103 and the output port 105 are connected, and the drain port 104 is closed. Then, compressed air is supplied from the passage 101 to the passage 102, and a portion of the compressed air in the passage 102 is supplied to the operating pressure port 143 through the passage 147. Therefore, the state of the air operated valve 144 is switched, the input port 140 and the output port 141 are connected, and the drain port 142 is closed. Therefore, compressed air is supplied to the air cylinder 38, the plunger 42 operates against the force of the compression spring, and the insertion/extraction lever 40 is released from the weight 16.

On the other hand, a portion of the compressed air supplied to the passage 102 is supplied to the operating pressure port 112, and the state of the air operated valve 60 is switched. Therefore, compressed air is supplied to the second air chamber 81, compressed air is discharged from the first air chamber 80, and the bracket 18 is lowered from the top dead center. As described above, since the insertion/extraction lever 40 is released from the weight 16, the bracket 18 descends while the bracket arm 19 holds the weight 16.

(Ending process 4)
When the bracket 18 supporting the weight 16 descends from the top dead center, the state of the mechanical valve 100 is switched. Therefore, the compressed air in passage 102 is discharged to drain port 104. While the bracket 18 is lowered, the states of the air operated valves 60, 85 do not change. When the bracket 18 reaches the bottom dead center as shown in FIGS. 9 and 10D, the weight 16 also reaches the bottom dead center. When the bracket 18 reaches the bottom dead center, the state of the mechanical valve 91 is switched. Therefore, input port 93 and output port 94 are connected, and drain port 95 is closed. Note that the valve switch fitting 49 is manually turned off, and even when the weight 16 reaches the bottom dead center, the valve switch fitting 49 is not turned on. After the bracket 18 and the weight 16 are stopped at the bottom dead center in this manner, the operator operates the stop button 45B on the operation panel 45 to stop the air compressor 56 and turn off the select switch 149. When the air compressor 56 is stopped, compressed air is discharged from the air cylinder 38, the plunger 42 moves from the retracted position to the forward position and stops due to the force of the compression spring, and the frozen butter striking device 10 returns to its initial state. .

(Effects of embodiment)
According to the frozen butter striking device 10, the hammer support mechanism 28 connects the butter hammer 14 between the receiving plate 13 and the support base 11 so as to be movable within a predetermined range in the vertical direction. Therefore, when the butter hammer 14 receives a striking force from the weight 16, the butter hammer 14 can be lowered while being in contact with the package 23. Therefore, it is possible to reliably apply a striking force to the frozen butter 22 housed in the package 23, and to destroy, ie, break, the frozen butter 22. Furthermore, when the package 23 containing the frozen butter 22 is placed on the support stand 11, the dimensional difference in the vertical direction between the frozen butter 22 and the package 23 can be absorbed. Furthermore, when the operator places the package 23 on the support stand 11 in the second step and slides the package 23 to enter the package 23 under the butter hammer 14, the weight 16 is held at the top dead center. ing. Further, the butter hammer 14 is lifted upward by a tension coil spring of a hammer support mechanism 28. That is, the mass of the weight 16 and the mass of the butter hammer 14 are not added to the package 23, and the operation of placing the package 23 on the support base 11 and sliding it can be performed smoothly.

Further, the protrusion 32 of the weight 16 is movable in the vertical direction within the hole 27 provided in the receiving plate 13. Therefore, the butter hammer 14 can be reliably struck by the weight 16. Further, a pipe guide 15 is provided that prevents the weight 16 from moving in a direction intersecting the vertical direction. Therefore, the weight 16 can be prevented from moving in a direction intersecting the vertical direction, and the position at which the frozen butter 22 is struck can be prevented from shifting in the plane direction. Further, the weight support mechanism 20 is attached to the pipe guide 15. Therefore, there is no need to provide a dedicated element for supporting the weight support mechanism 20.

Further, as shown in FIG. 3, in a plan view of the receiving plate 13 from directly above, the plurality of support shafts 41 are respectively arranged on the same circumference centered on the reference position A1. Therefore, the timing at which the two insertion/removal levers 40 are engaged with the weight 16 and the timing at which they are released can be synchronized. Therefore, the center of the weight 16 can be prevented from being tilted with respect to the virtual line B1. Further, as shown in FIG. 3, in a plan view of the receiving plate 13 from directly above, the protrusion 32 of the weight 16 is arranged centered on the reference position A1. Therefore, the center of the weight 16 can be prevented from tilting with respect to the imaginary line B1, and the position where the protrusion 32 hits the package 23 and the frozen butter 22 can be prevented from deviating from the reference position A1.
